Display drive circuit and drive method thereof and display device

Abstract

The invention discloses a display drive circuit and a drive method thereof and a display device. An eye tracking module is integrated in a data driven chip, the eye tracking module can determine eye-gaze coordinates according to eye images sent by an eye image acquisition device, a graphics processor processes a to-be-displayed image according to the eye-gaze coordinates sent by the eye tracking module, and finally the data driven chip controls a connected display panel to display according to the to-be-displayed image which is obtained after processing and sent by the graphics processor. Dueto the fact that the eye tracking module is integrated in the data driven chip, that is to say, eye image processing is completed in the data driven chip, in this way, the workload of the graphics processor can be reduced, and then system delay is reduced and the user experience is improved. In addition, compared with design that the eye tracking module is separately arranged in a translation circuit, the circuit integration of the display drive circuit can be improved, and the circuit complexity is lowered.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display driving circuit, a driving method thereof and a display device. Background technique [0002] At present, the common problem faced by virtual reality technology (VR / AR) is that the user's computer hardware cannot meet the display device's demand for high-definition rendering. In order to solve this problem, the most recognized way at present is the local rendering technology combined with eye tracking. In the process of human eye imaging, the central fovea image is clear and the visual acuity is high, while the peripheral image is blurred. Therefore, in the process of image rendering, it is only necessary to render the small area of ​​the fovea, and blur the peripheral field of view. When the eyeball rotates, the high-definition rendering area changes with the change of the gaze point, which not only ensures the image quality but also reduces the load on the Graphics...
