Background

With the development of Display technology, flat panel Display devices such as Liquid Crystal Displays (LCDs) and Organic Light Emitting Diodes (OLEDs) have the advantages of high image quality, power saving, thin body, and wide application range, and thus are widely used in various consumer electronic products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, and desktop computers, and become the mainstream of Display devices.

Most of the existing liquid crystal displays in the market are backlight liquid crystal displays (lcds), which include a liquid crystal display panel and a backlight module (backlight module). The liquid crystal display panel operates on the principle that liquid crystal molecules are filled between a thin film Transistor Array Substrate (TFT Array Substrate) and a color film Substrate (color filter, CF), and driving voltages are applied to the two substrates to control the rotation direction of the liquid crystal molecules, so that light of the backlight module is refracted out to generate a picture.

In order to align the liquid crystal molecules in a specific rotation direction, alignment films are required to be formed on the inner sides of the thin film transistor array substrate and the color filter substrate, and the alignment films can be used for limiting the alignment state of the liquid crystal molecules. In a conventional method for fabricating an alignment film, a PI (Polyimide) solution in which a polymer compound is dissolved is sprayed on a substrate surface on which the alignment film is to be fabricated, and the PI solution is diffused to make the film layer uniform. However, due to the anisotropy of PI, the final position of its diffusion everywhere to the panel edge cannot be predicted. If the PI is diffused to the frame glue area, frame glue defects can be formed, and poor display is caused. Therefore, a transition region with a certain width is reserved on the display panel at present to prevent PI from diffusing to the frame glue region, but the periphery of the display panel is always provided with a black frame visible to naked eyes to influence the display effect of the display panel.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention. In the present application, unless indicated to the contrary, the use of the directional terms "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, and more particularly to the orientation of the figures of the drawings; while "inner" and "outer" are with respect to the outline of the device.

The embodiment of the application provides a display device and a display panel 200 thereof. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

The present application provides a display device that can be mounted in various products having a display function. For example, the electronic product may be a smart terminal, a notebook computer, a photographing apparatus, a wearable apparatus, an electronic scale, a vehicle-mounted display, a television, and the like.

Referring to fig. 1, the display device includes a housing 100 and a display panel 200 installed in the housing 100. Referring to fig. 2 and fig. 3, the display panel 200 includes an array substrate 210 and a color filter substrate 220 disposed opposite to each other, and a polyimide film 230, a retaining wall 240, a sealant 250 and an acrylic film 260 disposed between the array substrate 210 and the color filter substrate 220.

The array substrate 210 includes a display area 201 and a non-display area 202 surrounding the display area 201.

The polyimide film 230 is coated on the display region 201 and diffused toward the non-display region 202 around the display region 201 until a uniform state is achieved.

The retaining wall 240 is disposed in the non-display region 202, surrounding the display region 201, and mainly provides support between the array substrate 210 and the color filter substrate 220. It is understood that the retaining wall 240 is generally formed by a plurality of pillars 241 spaced around the display area 201, and the pillars 241 spaced around the display area 201 can provide more stable and reliable support between the array substrate 210 and the color filter substrate 220. The cylinder 241 may be made of a material such as a photoresist or a Spacer (PS), and may be in a shape of a prism or a cylinder, and in the embodiment of the present disclosure, the cylindrical PS cylinder 241 is taken as an example for explanation. Meanwhile, the interval between the pillars 241 needs to be set between 200 micrometers and 1000 micrometers, when the pillars 241 are needed to bear and block the polyimide, the interval between two adjacent pillars 241 can be narrow, and the effect of blocking part of the polyimide is achieved through a dense arrangement mode.

The sealant 250 is disposed in the non-display region 202 and surrounds the retaining wall 240. Two sides of the sealant 250 are respectively bonded to the array substrate 210 and the color filter substrate 220, so that the array substrate 210 is connected and fixed to the color filter substrate 220.

The acrylic film 260 is disposed in the non-display region 202 and located inside the sealant 250. The acrylic film 260 is disposed around the display region 201 to prevent the polyimide film 230 from diffusing into the sealant 250.

In an embodiment of the disclosure, the acrylic film 260 may be disposed between the retaining wall 240 and the sealant 250, may be disposed on a side of the retaining wall 240 deviating from the sealant 250, and may be disposed at other positions, which is not limited herein. Reference will now be made in detail to specific embodiments.

Referring to fig. 4, in some embodiments of the present disclosure, the acrylic film 260 is disposed between the retaining wall 240 and the sealant 250, and a portion of the polyimide film 230 is blocked by the retaining wall 240 and another portion of the polyimide film passes through the gap between the pillars 241 forming the retaining wall 240 and extends to the acrylic film 260 during the diffusion film forming process on the array substrate 210. The polyimide film 230 is blocked by the acryl film 260 to stop diffusion due to the repulsive property between polyimide and acryl. In the method, the retaining wall 240 blocks part of polyimide from diffusing, and the acrylic film 260 blocks the rest of polyimide from diffusing, so that the situation that the blocking effect of the acrylic film 260 is poor due to too much polyimide in a part of regions is avoided, and the disordered diffusion of the polyimide film 230 is effectively controlled.

In the embodiment, the distance between the acryl film 260 and the sealant 250 can be controlled within 100 micrometers, and the distance between the acryl film 260 and the retaining wall 240 can also be controlled within 100 micrometers. However, in general, the forming of the acrylic film 260 needs to use the retaining wall 240 as a reference, so the distance between the acrylic film 260 and the retaining wall 240 is smaller than the distance between the acrylic film 260 and the sealant 250. Meanwhile, the width of the molded acrylic film 260 is between 500 micrometers and 1000 micrometers. Therefore, the width of the transition region reserved on the display panel 200 can be reduced from 5.0 mm to 2.0 mm to 3.0 mm, so that the technical problem that the display effect of the display panel 200 is influenced by the fact that a black frame left on the display panel 200 is too wide in the prior art is solved, and the screen occupation ratio of the display device adopting the display panel 200 is improved.

Referring to fig. 5, in other embodiments of the present disclosure, the acrylic film 260 is disposed on a side of the retaining wall 240 away from the sealant 250, i.e., an inner side of the retaining wall 240. In the process of diffusion film formation on the array substrate 210, when the polyimide film 230 extends to the acrylic film 260, due to the repulsion property between polyimide and acrylic, the polyimide film is blocked by the acrylic film 260 and stops diffusion. In the above method, the polyimide diffusion is directly blocked by the acrylic film 260, so that the boundary of the polyimide film 230 can be effectively controlled near the edge of the display region 201, and the width of the transition region is further reduced to be close to 0. Therefore, the purpose of the ultra-narrow frame of the display panel 200 is achieved, the screen occupation ratio of the display device adopting the display panel 200 is improved, and the display effect of the display panel 200 is effectively improved. Meanwhile, in the present embodiment, the distance between the acrylic film 260 and the retaining wall 240 is also controlled within 100 micrometers, and the width of the molded acrylic film 260 is also between 500 micrometers and 1000 micrometers.

Referring to fig. 6, in still other embodiments of the present disclosure, the interval between two adjacent pillars 241 constituting the retaining wall 240 is about 500 to 1000 micrometers, and the acrylic film 260 may also be disposed between two adjacent pillars 241 to fill the gap between the pillars 241. In the process of diffusion film formation of the polyimide film 230 on the array substrate 210, a portion of the polyimide film is blocked by the blocking wall 240, and another portion of the polyimide film diffuses toward the gaps between the pillars 241. However, the acryl film 260 is disposed between the pillars 241, and the polyimide is blocked by the acryl film 260 to stop diffusion due to a repulsive property between the polyimide and the acryl. In the above method, the barrier wall 240 and the acrylic film 260 jointly block the polyimide diffusion, so that the boundary of the polyimide film 230 can be effectively controlled near the edge of the display region 201, and the width of the transition region can be further reduced to be close to 0. Thereby realize the purpose of the super narrow frame of display panel 200, improved the screen that adopts this kind of display panel 200's display device and accounted for the ratio, effectively promoted display panel 200's display effect, set up ya keli membrane 260 the quantity that also can save the ya keli in the manufacturing process between cylinder 241 simultaneously, and then reduce manufacturing cost.

Referring to fig. 7, further, in some embodiments of the present disclosure, the acrylic film 260 may also be disposed around the cylinder 241. In the process of diffusion film formation on the array substrate 210, when the polyimide film 230 extends to the acrylic film 260, due to the repulsion property between polyimide and acrylic, the polyimide film is blocked by the acrylic film 260 and stops diffusion. However, if the polyimide in a certain region is too much to overflow, the blocking wall 240 and the acrylic film 260 between the blocking wall 240 and the plastic frame can block the polyimide. The method forms a plurality of barrier lines for blocking the polyimide diffusion, and can further improve the reliability of the structure for blocking the polyimide diffusion. Meanwhile, the acrylic film 260 surrounding the pillars 241 may be formed on the array substrate 210 prior to the pillars 241 to serve as a positioning mark when the pillars 241 are arranged on the array substrate 210, thereby improving the arrangement accuracy of the pillars 241.

Meanwhile, the thickness of the acrylic film 260 is between 0.5 and 7.0 microns. The acryl film 260 having a thickness of 0.5 to 7.0 micrometers also has advantages of simple structure and low cost, and does not increase the thickness and weight of the finished display panel 200.

The display device and the display panel 200 thereof provided by the embodiments of the present application are described in detail above, and the principles and embodiments of the present application are explained herein by applying specific examples, and the description of the embodiments above is only used to help understand the method and the core idea of the present application; meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
