Technical Field

Background

Liquid Crystal Displays (LCDs) have many advantages such as thin body, power saving, and no radiation, and are widely used, for example: liquid crystal televisions, mobile phones, Personal Digital Assistants (PDAs), digital cameras, computer screens, notebook computer screens, or the like.

Most of the existing liquid crystal displays in the market are Backlight type liquid crystal display devices, which include a Backlight module (Backlight module) and a liquid crystal panel disposed on the Backlight module. Among them, the Liquid crystal panel generally includes a Color Filter (CF) Substrate, a Thin Film Transistor Array (TFT) Substrate, and a Liquid crystal layer (Liquid crystal layer) disposed between the two substrates. The working principle of the existing backlight type liquid crystal display device is that the rotation of liquid crystal molecules in a liquid crystal layer is controlled by applying driving voltage to refract light rays of a backlight module, and the light rays generate color pictures through the color filter substrate.

At present, a common backlight type liquid crystal display product in the market generally does not have a Local Dimming function, and even if a part of liquid crystal Television (TV) models have the Local Dimming function, because the number of backlight partitions is not enough (in the prior art, the number of backlight partitions is 10 to 200), under a special picture, a display defect still exists: the bright area is not bright enough, and the dark area is not dark enough, so that the contrast is poor, and the watching experience of a user is influenced.

In view of the above problems, a dual LCD display panel is gradually developed, and a lower LCD display panel and a backlight module of the dual LCD display panel form a pixel local dim structure together, which is beneficial to normal display of an upper LCD display panel. Namely, two layers of LCD display panels are jointed, and the brightness switch of the corresponding upper LCD pixel can be controlled through the lower LCD, thereby achieving the purpose of pixel-level backlight modulation.

However, the above-mentioned double LCD display panel may be easily subject to interference fringes in the attached region, regardless of whether a single-layer POL or a multi-layer POL is used.

Therefore, it is desirable to provide a display panel to solve the above problems.
