Problems solved by technology

[0002] In the field of flat panel display technology, liquid crystal display technology occupies the mainstream of flat panel display products due to its advantages such as low power consumption and long life. For existing production lines, liquid crystal panels of various sizes are extremely complete and mature. Therefore, liquid crystal display panels The cost is also low. However, the LCD color characteristics of the existing production line are still its shortcoming. It is difficult to break through the NTSC 100% index. In the field of competitions and e-sports, the LCD panel with low response speed will still have smearing. In the large-screen display, the viewing angle of the LCD also needs to be improved.

Embodiment 1

[0052] Such as figure 1 As shown, the structure of the quantum dot liquid crystal display panel is determined to be the backlight LED and the light guide plate uLED from bottom to top, the transverse polarizer, and the lower substrate of the liquid crystal cell (the addressing electrode array is arranged inside the liquid crystal cell, and the addressing electrodes are interlaced in the rows and columns. There are dislocation convex trihedral electrodes), quantum dot liquid crystal molecules (separated by black photoresist array), upper substrate of the liquid crystal cell, vertical polarizer, when the addressing signal selects the pixel module, the nematic liquid crystal is affected The electric field deflects, and the deflection angle is determined by the electric field. The larger the angle, the more light is emitted, and vice versa; when there is no electric field, the liquid crystal state is as figure 2 As shown, at this time, no light passes through the liquid crystal c...

Embodiment 2

[0057] Such as Figure 7 As shown, determine the structure of the display panel of the backlight quantum dot liquid crystal molecules of the white light LED, the materials and parameters are the same as in Example 1, and the electrode part of the liquid crystal cell is adjusted as follows: deposit a whole piece of transparent electrode material on the transparent glass, and deposit the entire transparent electrode material on the electrode. Coat a layer of photoresist, use photolithography to define row and column addressing electrodes and strip electrodes with comb-like dislocation distribution, and then etch. After the substrate is fabricated, clean and dry the substrate, and then spin-coat it The black photoresist is used for the production of the sub-pixel array Bank, and the display panel of the quantum dot liquid crystal molecules can be obtained by pouring the three-color quantum dot liquid crystal molecules for glue sealing and assembly.

Abstract

The invention relates to a display panel based on quantum dot liquid crystal molecules, which is characterized in that it includes a bottom-up light guide plate uLED, a transverse polarizer, a lower substrate of a liquid crystal cell, quantum dot liquid crystal molecules, an upper substrate of a liquid crystal cell, and a vertical direction polarizer; the light guide plate uLED is provided with a backlight LED; the liquid crystal cell is arranged with an address electrode array, and dislocation electrodes are arranged at the intersection of the row and column address electrodes; the quantum dot liquid crystal molecules are processed by black photolithography The glue array is separated; the opening and closing mode of the liquid crystal panel is adjusted by means of dislocation electrodes, and the function of the liquid crystal panel, that is, the display pixel, is realized by controlling whether the backlight source excites the quantum dot liquid crystal. The invention removes the color film layer of the traditional liquid crystal display panel, greatly improves the light utilization efficiency, isolates the crosstalk between the light of each pixel, and simplifies the structure of the liquid crystal display panel.
