Problems solved by technology

Since the printed circuit board 1 is completely fixed on the backboard by the screws 3, the printed circuit board 1 has no moving space, which easily leads to stress concentration on the second flexible printed board 6, causing the second flexible printed board 6 to be damaged and broken. affect the display effect of the display substrate 18
If a gap is formed between the printed circuit board 1 and the backplane, so that the second flexible printed board 6 has a movable space, this will cause poor contact between the screw 3 and the first electrostatic discharge area 4, thereby causing static electricity on the printed circuit board 1 to fail. It is completely released to the backplane through screw 3, resulting in abnormal display of the display module

Embodiment Construction

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention. It should be noted that, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily if there is no conflict.

[0032] Electrostatic discharge, or ESD (Electro-Static discharge), refers to the phenomenon of charge movement between objects with different potentials. The damage of static electricity to electronic components is fatal. The magnetic field generated around electronic components can cause malfunction of components and even lead to loss of life and property. According to relevant statistics, product failure cannot be ignored in circuit design.

Abstract

The embodiment of the invention provides a display module and a display device.The display module comprises a back plate and a printed circuit board arranged on the back plate, the printed circuit board is connected with the back plate through screws, the printed circuit board is provided with a first electrostatic discharge area and a first electrostatic discharge unit, and the first electrostatic discharge area is connected with the first electrostatic discharge unit. The first electrostatic discharge area is connected with the back plate through the screws to form a first electrostatic discharge channel, and the first electrostatic discharge unit is connected with the back plate to form a second electrostatic discharge channel; and static electricity in the printed circuit board can be completely released.

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] The liquid crystal display device is currently a large-scale display device, which has the advantages of high color gamut, lightness and thinness, fast response time, etc., and has mature technology in theoretical research and practical process. [0003] The liquid crystal display is a commonly used flat panel display at present, and the liquid crystal display module is the core display component in the liquid crystal display. [0004] figure 1 It is a schematic diagram of the structure of the connection between the printed circuit board and the backplane. like figure 1 As shown, the printed circuit board 1 is provided with through holes, and the screws 3 pass through the through holes of the printed circuit board 1 and are fixed on the lugs 5 of the backplane, thereby fixing the printed circuit boar...
