Display device and display module thereof

Abstract

The invention discloses a display device and a display module thereof. The display module comprises a frame, a panel, a back cover, a printed circuit board and a flexible printed circuit board, wherein the panel is fixedly arranged on the frame; the back cover is fixed to the frame; the printed circuit board and the panel are arranged in a spaced mode, the printed circuit board is connected with the back cover through fasteners, at least one of the printed circuit board and the back cover is provided with a long kidney-shaped hole, and the fasteners are arranged in the long kidney-shapes holes in a sliding mode; and the flexible printed circuit board is fixedly connected between the printed circuit board and the panel. Through sliding of the fasteners in the long kidney-shaped holes, the back cover and the printed circuit board can move relatively to adapt to structural deformation or tolerance of other components, and therefore the flexible printed circuit board is prevented from bending or bulging.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display module. The invention also relates to a display device with the display module. Background technique [0002] Existing display devices, especially notebook computers, usually have a flexible circuit board (FPC) 3, and the FPC is prone to bending or bulging, such as figure 2 As shown, and the FPC is relatively sensitive, once it bends or bulges, it will obviously affect its display effect, such as causing light leakage from the display screen (LO), thereby affecting the user's viewing quality. [0003] The existing display device usually also includes a printed circuit board (PCB) 1, a back cover (back cover) 5 and a panel (panel) 2, and the PCB and the back cover are usually connected by fasteners, such as screw connections; Panel, FPC and PCB are fixedly connected in turn, refer to figure 1 with figure 2 . There are many reasons for the FPC in the displa...

AI Technical Summary

Problems solved by technology

There are many reasons for the FPC in the display device to bend or bulge, among which the most notable ones are: on the one hand, during the assembly process, due to the existence of component tolerances or operational tolerances, such as the size tolerance of the backcover, the size tolerance of the panel, and the size of the PCB Tolerances or tolerances of the bonding process usually cause misalignment of the mounting holes of the PCB and the back cover for the fastener 4 to pass through during the assembly process, so that the fastener 4 is installed on the two mounting holes After the hole is inserted, it will cause the FPC to bend or bulge; on the other hand, after the display device is assembled, in the later use process, due to changes in itself or other factors such as the temperature of the external environment, the components may be deformed, such as Structural deformation of the PCB or back cover will cause the original straight FPC to deform and cause bending or bulging

In addition, the deformation of the FPC will stress itself, affecting its service life

[0004] The problem of FPC bending or bulging has plagued people for a long time. It has always attracted attention but failed to find a practical solution. It has become a technical problem.
