Method for detecting crosstalk between adjacent pixels of display panel

Abstract

The invention relates to a method for detecting crosstalk between adjacent pixels of a display panel. The method comprises the following steps of: arranging an optical grating in front of the display panel, allowing a luminance meter to receive light emitted from even pixels and preventing the luminance meter from receiving the light emitted by odd pixels; measuring overall brightness of the display panel by the luminance meter and recording the overall brightness as a first brightness value when an odd pixel row and an even pixel row simultaneously display black pictures; measuring the overall brightness of the display panel by the luminance meter and recording the overall brightness as a second brightness value when the odd pixel row displays a white picture and the even pixel row displays a black picture at the same time; and recording a third brightness value obtained by subtracting the first brightness value from the second brightness value, and judging amplitude of the crosstalkbetween the adjacent pixels according to the third brightness value. According to the method, the amplitude of the crosstalk between the adjacent pixels of the display panel can be detected; and the detection method is simple and practical, has no need of complex instruments and the like.

Description

Technical field [0001] The present invention relates to display technology, in particular to a method for detecting crosstalk between adjacent pixels of a display panel. Background technique [0002] The dual-view display technology is a way of setting a grid in front of the display panel to realize the display mode of different images observed at different viewing positions. [0003] figure 1 It is a schematic diagram of the display technology of a dual-view display in the prior art, from figure 1 It can be seen that the dual-view display includes a display panel 1 and a grid 2 arranged in front of the display panel 1, and the above-mentioned display panel 1 includes odd-numbered pixel columns 11 and even-numbered pixel columns 12, and the grid 2 includes light blocking bars and The odd-numbered pixel column 11 displays the first image, and the even-numbered pixel column 12 displays a second image different from the first image. The first image is gathered to the left viewing area...

Problems solved by technology

[0005] Crosstalk between adjacent pixels not only occurs in dual-view displays, but also in general displays. Therefore, in the process of producing displays, manufacturers need to screen out the crosstalk between adjacent pixels from multiple display panels. As small a display panel as possible, but there is currently no way to detect the degree of crosstalk between adjacent pixels
