Abstract

The invention relates to a backlight module, a backlight adjusting method and a display device, the backlight module is used for providing backlight for an embedded touch display panel adopting intra-frame touch detection, and the embedded touch display panel adopting the intra-frame touch detection has at least one cross grain area during display; the backlight module comprises a backlight assembly and a driving module, the backlight assembly comprises a substrate and at least one first light-emitting unit arranged on the substrate, and each first light-emitting unit corresponds to each cross grain area; the driving module is connected with each first light-emitting unit and used for adjusting the light-emitting brightness of the corresponding first light-emitting unit according to the picture signal of each cross grain area so as to carry out brightness compensation on each cross grain area. According to the invention, the cross grain phenomenon of the embedded touch display panel adopting intra-frame touch detection during display can be improved, the image display quality is improved, the hardware change is small, and the cost is low.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a backlight module, a backlight adjustment method and a display device. Background technique [0002] With the development of liquid crystal display panel technology, the liquid crystal display panel has developed from a separate display function to an integration of display and touch. In order to improve the portability of the device, the touch and display driver integration (TDDI) method is often used to reduce the thickness of the touch display module, thereby achieving the effect of reducing the overall thickness of the panel. [0003] Current touch detection technologies include an inter-frame touch detection (LVB, Long Vertical Blank) technology and an intra-frame touch detection (LHB, Long Horizontal Blank) technology. The existing in-cell touch panel (In Cell TouchPanel) generally adopts the LHB touch method of TDDI, that is, the display and the touch wor...
