Problems solved by technology

[0004] The above-mentioned full screen generally needs to be tested for dripping sweat before leaving the factory to detect whether sweat will enter the screen body during actual use and affect the performance of the device in the screen body
However, during the sweat drop test, the metal traces in the above-mentioned screen are easily corroded, resulting in a low pass rate of the sweat drop test of the screen

Embodiment Construction

[0041] As mentioned in the background technology, in the display module in the related art, the metal wiring in the screen body 104 is easily corroded during the sweat drop test, resulting in a low pass rate of the full screen sweat drop test. The inventors found that the reason for this problem is: if figure 1 As shown, due to the existence of the spacer 109 , a triangular gap 107 is formed between the flexible circuit board 106 , the spacer 109 and the corresponding support layer 105 disposed on the backlight side of the screen body 104 . During the sweat drop test, sweat usually drips from the top of the screen body 104 on the edge of the flexible circuit board 106. Since the sweat itself is liquid and has fluidity, the sweat easily enters the gap 107 and accumulates, causing the sweat to be exposed to the surface of the flexible circuit board 106. The edge of the bonding area 1043 of the gap 107 enters the screen body 104, causing corrosion of the metal traces in the scree...

Abstract

The invention provides a display module and a mobile terminal, relates to the technical field of display, and is used for solving the technical problem that the qualified rate of a screen body is relatively low due to the fact that a metal wire in the screen body is easy to corrode in a sweat dropping test process of the display module. The display module comprises a screen body, a supporting layer, a cushion block and a flexible circuit board, wherein the supporting layer, the cushion block and the flexible circuit board are located on the backlight side of the screen body. The screen body is provided with a display area, a bending area and a bonding area, wherein the bending area and the bonding area sequentially extend outwards from the display area, and the cushion block is located between the screen body of the bonding area and the supporting layer. One end of the flexible circuit board is attached to the screen body of the bonding area, the other end of the flexible circuit board is located on the side, away from the bending area, of the cushion block and attached to the supporting layer, and a gap is defined by the flexible circuit board, the cushion block and the supporting layer. A flow guide groove is formed in an opening, close to the gap, of the supporting layer in the extending direction of the gap; and the flow guide groove is used for guiding sweat out of the gap, so that the qualified rate of the screen body during sweat dropping test is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display module and a mobile terminal. Background technique [0002] At present, full screen has become the trend of electronic products, especially smart phone products. Whether it is a display accessory manufacturer or a complete machine manufacturer, they are all working hard to further reduce the width of the mobile phone frame and expand the display ratio. [0003] The mainstream solution adopted by the full screen is the pad part bending solution. The full screen screen body includes a display area, a bending area and a bonding area arranged in sequence. The bonding area of ​​the screen body needs to be bent to the backlight side of the screen body. , so that only the display area is reserved on the display surface of the screen, thereby increasing the screen-to-body ratio of the screen. In the process of bending the bonding area of ​​the screen to the backligh...
