Technical Field
The application relates to the field of display, in particular to a color filter, a preparation method of the color filter and a display panel.
Background
The oled display technology has advantages of self-luminescence, low power consumption, light weight, and no liquid crystal flowing layer, and thus is widely used in flexible displays. Among them, the flexible organic light emitting diode structure generally includes a thin film transistor based on a flexible substrate, a light emitting layer, an encapsulation layer based on a multi-layer thin film, and a circular polarizer. For the organic light emitting diode device, although the polarizer can reduce the reflectivity of ambient light, increase the contrast ratio thereof and improve the outdoor readability of the organic light emitting diode, about 58% of light is lost, and in addition, the development of dynamically bendable display products is limited due to the characteristics of large thickness and fragile texture, so that the problem is solved by adopting the color filter instead of the polarizer in the conventional organic light emitting diode device.
At present, an ink-jet printing technology is generally adopted to form a color filter, wherein a black matrix is firstly prepared as a blocking unit to form a pixel pit, and then ink is dripped into the pixel pit to cure the ink to form a color resistance unit.
Therefore, how to effectively control the thickness of the color resistance unit in the color filter is a challenge for panel manufacturers all over the world.
