Abstract: Disclosed is a method for adjusting a displayed image. The method includes obtaining brightness information of a plurality of color channels of a currently displayed image; determining a target color channel with abnormal brightness from the plurality of color channels based on the brightness information; obtaining stimulus information of the target color channel, and determining a target grayscale from a predetermined grayscale interval based on the stimulus information; and determining brightness and chromaticity corresponding to the target grayscale, and adjusting the displayed image based on the brightness and chromaticity corresponding to the target grayscale.

Abstract: A light source module, a liquid crystal display device, and a display apparatus are provided. The light source module disposes a plurality of micro structures disposed at intervals on a light guide surface of a light guide plate and disposes a sum of areas of the micro structures on an unit area on the light guide surface gradually increasing from a light incident side to a light exiting side, which can improve uniformity of light exiting brightness of each region of the light guide plate.

Abstract: A polarizer, a liquid crystal display module, and a simulation method for liquid crystal display compensation are disclosed. A compensation film includes three layers of uniaxial compensation films. Each of the three uniaxial compensation films has a slow axis which is configured at a same slow axis angle and is perpendicular to an absorption axis of a polarizing film, and each of the three uniaxial compensation films has only an in-plane phase difference or an out-of-plane phase difference. In this manner, it only needs to adjust thickness of each layer of the compensation film when simulating a design of the compensation film or preparing the polarizer, so that an in-plane phase difference and an out-of-plane phase difference of the compensation film can be separately set at will.

Abstract: A light source module, liquid crystal display device and display apparatus. The light source module comprises a light guide plate and a light source disposed on the light guide plate side, and a plurality of micro structures are disposed on a light guide surface of the light guide plate. The light source module can provide a reflective liquid crystal display panel with an area light source similar to ambient light to improve light exiting brightness of the reflective liquid crystal display panel such that reflective liquid crystal display panel also has a better display effect in a dark environment and under a condition without ambient light.

Abstract: A polarizer and a display device are provided. In the polarizer, on a basis of using an optical compensation layer to compensate a birefringence of liquid crystal molecules in a liquid crystal layer, a liquid crystal compensation layer is configured to compensate the birefringence of the liquid crystal molecules in the liquid crystal layer. The liquid crystal compensation layer adjusts a compensation value through a refractive index difference and a thickness of the liquid crystal molecules, so an adjustment range is large and a restriction is small, which can be matched with a high phase difference of the display device, and further improves side-view light leakage in a dark state of the liquid crystal display.

Abstract: A display device is provided. In the present application, a liquid crystal compensation layer is provided on both first polarizer and second polarizer, and an improvement of compensation value is not realized by stretching the liquid crystal compensation layer but by adjusting the refractive index difference and thickness of the liquid crystal molecules, so the adjustment range is large, the restriction is small, and it can be matched with the high phase difference of the liquid crystal display panel. Therefore, the dark state side-view light leakage of the liquid crystal display panel and the contrast ratio of the liquid crystal display panel are improved, and the image quality is enhanced.
