Description

monitor

The novel creation involves the field of optoelectronics, especially a display.

In today's displays, the general rigid circuit board is fixed to the frame by a locking component such as a screw. The locking element partially protrudes from the rigid circuit board to have a high height, which is disadvantageous for reducing the frame of the display. At the same time, when the frame is reduced, the space for locking the screws is reduced, which makes assembly difficult. In addition, the display is connected to the panel module and the rigid circuit board through the flexible circuit board. If the display is applied to a notebook computer or other folded device, when performing the folding hinge test (Hinge Test), because The rigid circuit board is too strong in the force of the screw to the frame, and it is easy to cause the flexible circuit board to be broken when folded.

For this problem, at this stage, it is necessary to fix the rigid circuit board by means of tape sticking instead of the screw locking method. However, due to the soft texture of the tape, when an external force is applied, a large deformation amount is generated, and the rigid circuit board may slip or fall off, causing the flexible circuit board to be broken, and when the impact is large. The rigid circuit board may also collide with the backlight module or the panel module to cause damage to the display.

In order to solve the problems of the prior art, a display is provided herein. The display includes a housing, a panel module, a rigid circuit board, a flexible circuit board, at least one buffer member, and an insulating shield. The housing has a bearing surface. The panel module is disposed on the bearing surface of the housing. The rigid circuit board is located on the outside of the housing. The flexible circuit board connects the panel module and the rigid circuit board. The at least one buffer member is disposed between the housing and the rigid circuit board, and the at least one buffer member has opposite first and second surfaces, and the first surface and the second surface are respectively in contact with the housing and the rigid circuit board. The insulating shield covers the rigid circuit board, the flexible circuit board and the at least one buffer member.

In the display, the buffer member abuts the housing and the rigid circuit board to maintain the gap between the housing and the rigid circuit board, thereby avoiding the rigid circuit board being broken due to the force slip of the rigid circuit board during assembly or transportation. . In addition, since the cushioning member can absorb the impact, the damage to the display when the external force is impacted is reduced, and the service life of the product is improved.
