Embodiment Construction

[0039] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0040] figure 1 , shows a schematic side view of a display module in the related art. Such as figure 1 As shown, the display module 100 in the related art includes a display screen 110 and a flexible circuit board 120 .

[0041] The display screen 110 sequentially includes a display layer 111 , a first conductive layer 112 and a light shielding layer 113 from top to bottom along the z-axis.

[0042] Edges of the display layer 111 , the first conductive layer 112 and the light shielding layer 113 form a first stepped shape. The first stepped shape includes a first-level "step" formed by the edges of the first conductive layer 112 and the display layer 111 and a second-level "step" formed by the edges of the light-shielding layer ...

Abstract

The invention discloses a display module and a mobile terminal, and belongs to the field of mobile terminal installation. The display module comprises a display screen and a flexible circuit board; the display screen comprises a display layer, a first conductive layer located below the display layer and a shading layer located below the first conductive layer; a gap is formed between the display layer and the edge of the first conductive layer, so that the edge of the first conductive layer is shielded by the display layer; the flexible circuit board comprises a substrate layer, a second conductive layer located on the substrate layer and a cover film located on the second conductive layer. The first conductive layer and the second conductive layer are electrically connected through the third conductive layer. According to the invention, the edges of the first conductive layer and the display layer are arranged at intervals, the edge of the first golden finger is shielded by the display layer, so that the first golden finger is not exposed outside, the probability that the first golden finger is corroded is reduced, the probability that the display screen cannot work normally is further reduced to a certain extent, and the working stability of the display module is improved.

Description

technical field [0001] The present disclosure relates to the field of mobile terminals, in particular to a display module and a mobile terminal. Background technique [0002] Generally, a display screen of a mobile terminal is electrically connected to a display driver chip and a main circuit board through a flexible printed circuit (FPC). [0003] In related technologies, the display screen of the mobile terminal and the flexible circuit board are electrically connected by setting conductive materials to conduct their respective conductive layers. Since the conductive layer is easily corroded, the display screen may fail to work normally at a certain probability. Contents of the invention [0004] Embodiments of the present disclosure provide a display module and a mobile terminal to solve problems in the display module of mobile terminals in the related art. Described technical scheme is as follows: [0005] In one aspect, a display module is provided, and the display ...
