Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] An embodiment of the present invention provides a display module.

[0023] Such as figure 1 As shown, in one embodiment, the display module includes a backlight module 100 and a touch module 200 arranged in layers.

[0024] The backlight module 100 includes a metal frame 101. The metal frame 101 is generally made of iron to provide sufficient strength. Obviously, its material can be selected according to requirements in actual implementation. ...

Abstract

The invention provides a display module and a display device. The display module comprises a backlight module and a touch module which are arranged in a stacked mode, the backlight module comprises ametal frame, the touch module comprises a modulation signal line, and the modulation signal line is connected with a ground wire pin of the metal frame. According to the display module provided by theembodiment of the invention, the metal frame of the backlight module is connected with the modulation signal line of the touch module, so that in the working process of the touch module and when themodulation signal is output, the signals of the building port and the touch signal are the same, the voltage difference between the metal frame and the touch module is reduced, and the produced inverse piezoelectric effect is reduced; therefore, the possibility of a howling phenomenon is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] In the related technology, the display module may have howling phenomenon. Howling refers to the formation of a capacitor between the electrodes of the panel and the backlight iron frame of the backlight module. Poor, and further cause the inverse piezoelectric effect, resulting in vibration, that is, howling phenomenon. Contents of the invention [0003] Embodiments of the present invention provide a display module and a display device to solve the problem that the display module may generate howling. [0004] In the first aspect, an embodiment of the present invention provides a display module, including a stacked backlight module and a touch module, the backlight module includes a metal frame, the touch module includes a modulation signal line, The modulation signal line is connected to the groun...
