Problems solved by technology

However, when the cable P is inserted into a connector 14a of the circuit board 14, or when the cable P is pulled out from the connector 14a, the circuit board 14 will often move relative to the plastic frame 19 due to poor screw locking workability. , so that the circuit board 14 is inclined or bent, which not only easily leads to damage to the connector 14a, but also makes the contact between the cable P and the circuit board 14 poor, and affects the quality of the product

Abstract

The invention discloses a display device. The display device comprises a display panel and a backlight module, wherein the backlight module is arranged on one side of the display panel. The backlight module comprises at least one luminous source, a light source shade and a circuit board. The light source shade is provided with an accommodating part and at least one extended part, wherein the accommodating part is used for accommodating the luminous source and the extended part is positioned on the outer side of the accommodating part. In a method for fixing the circuit board, at least one positioning part of the circuit board is contacted with the extended part to limit the movement of the circuit board.

Description

technical field [0001] The invention relates to a method for fixing a circuit board of a display device and a backlight module, and in particular to a method for fixing a circuit board of a display device and a backlight module applied to a side-emitting backlight module. Background technique [0002] With the rapid progress of flat display panel manufacturing technology and its advantages of light weight, small size, low power consumption and low radiation, flat display panels are widely used in personal digital assistants (PDAs). ), notebook computers, digital cameras, mobile phones, computer screens and flat-screen TVs and other electronic products. Coupled with the industry's active investment in research and development and the adoption of large-scale production equipment, the quality of flat display panels has been continuously improved, and the price has been continuously reduced, thus rapidly expanding the application fields of flat display panels. [0003] Generall...
