Embodiment Construction

[0048] In the prior art, in order to solve the situation that the smear length of the dynamic image boundary is too long due to the slow response speed of the liquid crystal panel, it is usually to simply adjust the first position where the input grayscale signal changes (that is, the position where the brightness changes). A control voltage for one frame to change the display brightness on the time axis corresponding to the triangular waveform (increase or decrease). However, in fact, the prior art methods cannot completely improve the problem of double borders, and may even cause border brightening or border darkening. The present invention proposes a method for displaying image data, which not only adjusts the control voltage of the first subframe of the first frame at the place where the input grayscale signal changes (that is, the place where the brightness changes), but also adjusts the change of the input grayscale signal. The control voltage of the second subframe of t...

Abstract

The invention discloses a method for improving display image data of dual-border problem. The method comprises correcting sub picture frame of therein two frame data according with received pixel multiple frame data; displaying each sub frame data in multiple frame data in order. The method can be used in various frequency doubling technique including displaying high gray scale sub picture firstly and displaying low gray scale sub picture finally, or displaying low gray scale sub picture firstly and displaying high gray scale sub picture finally, all can improve dual-border and trailing smear phenomenon via the method provided by the invention, and has significant improvement especially in the display picture changing from low gray scale to high gray scale, and the display effect is increased simply and efficiently.

Description

technical field [0001] The invention provides a method for displaying image data, especially a method for displaying image data that can improve the double boundary problem. Background technique [0002] With the maturity of liquid crystal display technology, it has become a trend to use liquid crystal display panels as liquid crystal televisions. Generally, pulse-like image data is often formed by adding sub-frames at present, which is called pulse-like liquid crystal display technology; the common one in the prior art is to add a normally black (normally black) of subframes. see figure 1 . figure 1 Shown are two adjacent pixels 101 and 102, which respectively receive grayscale data A and B, and display them in a frame time Tf. see figure 2 . The first common pulse-like liquid crystal display technology in the prior art is to add a normally black sub-frame (normally black) when the pixels 101 and 102 receive the grayscale data A and B, in conjunction with the image f...
