Embodiment 1

[0020] like image 3 As shown, the method for reducing crosstalk of a dual-view display provided in an embodiment of the present invention includes:

[0021] S1: Obtain the original voltage corresponding to the gray scale to be displayed;

[0022] S2: Obtain the compensation voltage of the original voltage;

[0023] S3: Superimpose the original voltage and the compensation voltage to obtain the compensated voltage;

[0024] S4: Applying the compensated voltage to the pixel electrodes of the sub-pixels.

[0025] Due to the influence of the crosstalk phenomenon, the original voltage will have a deviation, and the function of the compensation voltage is to compensate this part of the deviation, reducing the influence of the crosstalk on the original voltage, and also reducing the deviation of the gray scale displayed on the sub-pixel, improving the display quality, so The technical problem that the display quality is affected due to the crosstalk phenomenon between adjacent su...

Embodiment 2

[0035] This embodiment is basically the same as Embodiment 1, the difference is: as Figure 4 As shown, in this embodiment, the value of the side compensation voltage is obtained according to the original voltage on the pixel electrode and the interference voltage on a certain side of the pixel electrode, specifically:

[0036] S21: Display the first image with a certain grayscale in the right viewing area of ​​the dual-view display, apply the original voltage Va corresponding to the gray scale to the pixel electrodes of the sub-pixels in the right viewing area, and display another gray in the left viewing area For the second image of the gray level, the original voltage Vb corresponding to the other gray level is applied to the pixel electrode of the sub-pixel in the left viewing area;

[0037] S22: Measure the grayscale displayed in the right viewing area, and adjust Va at the same time until the grayscale in the right viewing area reaches normal;

[0038] S23: At this time...

Embodiment 3

[0041] This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, the value of the side compensation voltage is obtained according to the original voltage on the pixel electrode and the interference voltage on a certain side of the pixel electrode, specifically: The value of the compensation voltage is selected from the pre-prepared side compensation voltage table according to the original voltage on the pixel electrode and the interference voltage on a certain side of the pixel electrode.

[0042]How many gray scales can be displayed by a sub-pixel, that is, the number of gray scales is fixed, and corresponds to the same number of different values ​​of the original voltage, usually 64 or 256. Using the calculation method of Vab in Embodiment 1 and Embodiment 2, all n kinds of values ​​of Va and all n kinds of values ​​of Vb can be calculated, and n×n Vabs in all combinations can be used to form the side compensation voltage table, as sho...

Abstract

The embodiment of the invention discloses a crosstalk reduction method of a double-vision display and the double-vision display, and belongs to the technical field of the double-vision displaying. The display quality influence caused by the crosstalk phenomenon between the adjacent sub-pixels of the existing the double-vision display is reduced. The crosstalk reduction method of the double-vision display comprises the steps of: obtaining the original voltage corresponding to the gray scale to be displayed; obtaining the compensating voltage of the original voltage; overlapping the original voltage and the compensating voltage to obtain the compensated voltage; and applying the compensated voltage onto the pixel electrodes of the sub-pixels. The double-vision display comprises an original voltage input circuit and a compensating voltage input circuit, wherein the original voltage input circuit is used for applying the original voltage corresponding to the gray scale to be displayed onto the pixel electrodes of the sub-pixels, the compensating voltage input circuit is used for obtaining the compensating voltage, and the compensating voltage is overlapped with the original voltage to be applied to the pixel electrodes. The crosstalk reduction method and the double-vision display are applied to the crosstalk influence reduction in the double-vision display.

Description

technical field [0001] The invention belongs to the technical field of dual-view display, and in particular relates to a method for reducing crosstalk of a dual-view display and a dual-view display. Background technique [0002] The dual-view display can display two images at the same time, viewed from the left viewing area and the right viewing area of ​​the dual-view display respectively. The parallax barrier method is a common technique to achieve double vision, and its structure is as follows figure 1 As shown, a grating is placed in front of the display unit so that the viewer can only see the display unit through the slit of the grating. When the structures and positions of the grating and the display unit are appropriate, a dual-view effect can be achieved. The specific principle is: the viewer in the left viewing area can only see a part of the sub-pixels on the display unit through the slit; while the viewer in the right viewing area can only see another part of t...
