Embodiment Construction

[0049] The present invention will be described with preferred embodiments and viewpoints. Such descriptions are to explain the structure and steps of the present invention, and are only used for illustration rather than to limit the patent scope of the present invention. Therefore, in addition to the preferred embodiment in the description, the present invention can also be widely implemented in other embodiments.

[0050] The present invention discloses a pixel voltage compensation method for a panel. By constructing a pixel voltage compensation table, the timing control unit uses a look-up table method to perform voltage compensation for pixels with wrong display voltages, so as to change the display voltage. The display voltage of the wrong pixel, so that the pixel presents the gray scale to be displayed, and then eliminates the phenomenon of color checkerboard and screen flickering. Applicable panels of the present invention may include, but are not limited to, color s...

Abstract

The invention discloses a method for compensating a pixel voltage of a display panel and framework. The method comprises the following steps: building a pixel voltage compensation table in an inquiry window unit; deciding a compensated gray scale of a pixel to be compensated by a sequential control unit according to the pixel voltage compensation table; transmitting the compensated gray scale to a source electrode controller by the sequential control unit; corresponding the compensated gray scale to a compensated voltage by the source electrode controller; and outputting the compensated voltage to the pixel to be compensated by the source electrode controller.

Description

technical field [0001] The invention relates to a voltage compensation method, in particular to a pixel voltage compensation method of a multi-scanning line multi-open structure display panel. Background technique [0002] Because the traditional liquid crystal display does not emit light by itself, it must use lighting to emit light in places where there is insufficient external light source. For example, the liquid crystal display of a watch uses a simple small light bulb as illumination; the liquid crystal display used in a car ammeter or an OA terminal, etc. is illuminated by a rear lighting source to obtain a clear display. These methods of using a thin white light source on the back are called backlights. A general liquid crystal display uses a color filter to filter the light source, so that a single pixel can display the components of the three primary colors at the same time, so as to display the desired color. In such a liquid crystal display with color filters, ...
