Abstract

The invention provides a display device and a display control method. The display device can be applied to a display panel. The display device comprises an in-panel gate driver (GIP) circuit, a GIP checking circuit and a display driver integrated circuit, the GIP circuit comprises a plurality of shift registers which are connected in series, and the shift registers can generate a plurality of gate driving signals to respectively control operation of a plurality of rows of display units in the display panel. The GIP checking circuit can sequentially check whether a plurality of specific gate driving signals in the gate driving signals are available, and the display driver integrated circuit can generate a checking result according to a signal from the display panel. And selectively adjusting the display data corresponding to the image according to the inspection result so as to enable the display panel to display the adjusted image.

Description

technical field [0001] The present invention relates to display control, in particular to a display device and a display control method applicable to the display device. Background technique [0002] Liquid crystal display (LCD) panels are widely used in various applications such as automotive display panels, and when the gate driving mechanism of the display panel fails, the traditional integrated circuit (IC) of the display driver does not There are no specific solutions to deal with such problems, and there may therefore be some risk of traffic accidents. In some cases, the display panel is not completely damaged, for example, part of it is still functional. Therefore, a novel method and architecture is needed to properly utilize the undamaged part of the gate drive mechanism to improve the safety of car drivers. Contents of the invention [0003] Therefore, an object of the present invention is to provide a display device and a display control method applicable to th...
