Abstract

The embodiment of the invention discloses a display module and a display device. The display module comprises a touch panel and a backlight module which are arranged in sequence. The touch panel comprises a touch sensor layer; the backlight module comprises a metal frame; and a conductive layer, arranged between the touch sensor layer and the metal frame and electrically connected with a grounding end. The conductive layer is arranged in the display module and electrically connected with the grounding end, the conductive layer can generate an electrostatic shielding effect, the potential difference between the touch panel and the backlight module is eliminated, noise generated in the display process can be directly transmitted to the grounding end instead of a touch panel controller, and the purpose of weakening noise is achieved. The anti-static interference capability of transmission of the LTPS module is effectively improved, and the influence of an electric field on use of the LTPS module is weakened, so that the LTPS module is better suitable for data transmission between the mainboard and the LTPS module, and the production yield and the product quality are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] With the wide application of Low Temperature Poly-Silicon (LTPS) displays in multimedia display systems, users have higher and higher requirements for LTPS display effects, such as: resolution, color saturation, high refresh rate, etc. [0003] For the high refresh frequency part, in order to display rich and colorful video information, the system frequency will become higher and higher; when the system frequency exceeds 40MHz, the traditional filter method is used to suppress the electrostatic discharge (Electro-Static discharge) , ESD) technology has also reached its application limit, resulting in different levels of noise problems on LTPS displays. The noise generated by LTPS displays can interfere with the sensing function of capacitive touch screens, and the touch thinning of smartphones exacerbates the ...
