Abstract

The invention provides a dynamic touching MURA compensation method and an LCD system thereof; the method comprises that: a touching position signal is generated according to a touching position of a touching event of an LCD screen; a signal compensation process of a pixel brightness signal relative to the touching position of an original pixel data is executed according to the touching position, thereby generating a pixel data to be displayed; and the pixel data to be displayed is displayed on the LCD screen. Moreover, the invention discloses an LCD system provided with dynamic touching MURA compensation, which comprises an LCD screen, a touching signal analyzing module, a display data processor, a dynamic MURA compensation unit and a source electrode driver.

Description

technical field [0001] The present invention relates to a display data compensation method and a related liquid crystal display system, in particular to a dynamic data compensation method for touch moiré (MURA) and a related liquid crystal display system. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) is currently the most widely used type of flat panel display, which has the characteristics of light and thin appearance, power saving and no radiation pollution. The working principle of the liquid crystal display device is to change the arrangement state of the liquid crystal molecules in the liquid crystal layer by changing the voltage difference between the two ends of the liquid crystal layer, thereby changing the light transmittance of the liquid crystal layer to display different images. In various electronic products including liquid crystal display devices, such as multimedia players, mobile phones or personal digital assistants (PDA...
