Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a method for quantifying the crosstalk effect of display screens on the human eye. Background Technology

[0002] When a solid-color background on an LCD screen is contrasted with a patch of another color, the brightness of the surrounding areas changes, causing image distortion. This is known as crosstalk. Due to the characteristics of human eye's brightness perception, crosstalk is more easily observed against a mid-grayscale background. In particular, crosstalk is more noticeable around a black square displayed in the center of a white screen.

[0003] Crosstalk is categorized into horizontal crosstalk and vertical crosstalk. When vertical crosstalk occurs, the vertical areas become darker due to the influence of black squares, while horizontal crosstalk causes the horizontal areas to become brighter. Crosstalk typically occurs more frequently in column inversion, frame inversion, and COM inversion modes; it is less common in the currently used dot inversion mode.

[0004] In the TN type, the voltage is higher in the black area in the center and lower in the white area around the edges. When the coupling capacitance between the data line and the pixel electrode is too large, the high voltage in the black area in the center will cause the voltage of the pixel electrodes on the top and bottom sides to be too high, resulting in the color of the top and bottom sides of the image becoming darker.

[0005] In some crosstalk situations, such as Figure 12 The original gray background image was affected by the white block in the middle, resulting in an abnormal display where the top part appeared darker and the bottom part appeared lighter.

[0006] There is currently no method to quantify the effects of crosstalk on the human eye. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are all within the scope of protection of this invention.

[0071] To quantify the effects of crosstalk on the human eye, a method for quantifying the effects of crosstalk on the human eye is proposed.

[0072] Example 1

[0074] Step 100: Compare the crosstalk region in the abnormal image with the normal region to determine the type of crosstalk; Step 200: Obtain the chromaticity and luminance coordinates of the crosstalk region and the adjacent normal region; Step 300: Quantify the difference between the crosstalk region and the adjacent normal region using the chromaticity and luminance coordinates and the deviation method.

[0075] In this embodiment, the normal area is the display area where no crosstalk occurs, for example, in Figure 2 The gray area in the image, and the two areas above and below it that are affected by the white block in the middle, are the crosstalk areas.

[0076] In this embodiment, the deviation method considers the difference in chromaticity and luminance coordinates of a point in the crosstalk region and its adjacent neighboring regions to quantify the human eye effect of the crosstalk region.

[0077] Crosstalk type can be either horizontal or vertical.

[0078] To quantify the visual effects of all crosstalk partitions, the abnormal images are first partitioned. Preferably, this can be implemented as follows:

[0084] The first crosstalk region is the gray-white area below the central white block that is affected by it, and the second crosstalk region is the black area above the central white block that is affected by it. By obtaining the (R, G, B) coordinates of the crosstalk region and its adjacent regions, and transforming them to the xy-plane coordinates through linear transformation and projection, the chromaticity and luminance coordinates are obtained. The difference between the crosstalk region and its adjacent regions is calculated using the deviation method, thus quantifying the effect of crosstalk on the human eye.
