Fixing method of liquid crystal display component and pcb board

Abstract

The invention is adapted to the technical field of structures of electronic products and discloses a liquid crystal display assembly and a fixing method for PCB plate thereof. The above liquid crystal display assembly comprises a display panel and a backing plate. The bottom of the backing plate is connected with a middle frame. The display panel is mounted to the middle frame. The periphery of the backing plate is connected with a surface frame used for fixing the display panel and the middle frame. The PCB plate is installed on the backing plate and electrically connected with the display panel via a flat cable. A connection assembly, elastically deformable, is arranged between the PCB plate and the backing plate. The liquid crystal display assembly and the fixing method for the PCB plate thereof have following beneficial effects: the PCB plate of the liquid crystal display assembly is installed easily and highly flexible; the flat cable is prevented from being pulled in order to ensure safety of the flat cable during transport and quality of a product; the fixing method for the PCB plate is easily operated and fixed with good stability; and convenience is provided for production and assembly of the liquid crystal display assembly.

Description

technical field [0001] The invention belongs to the technical field of electronic product structures, and in particular relates to a liquid crystal display component and a fixing method for a PCB board thereof. Background technique [0002] Currently, there are two main types of liquid crystal display products on the market. One is the side-light type, that is, the light source is injected from the surroundings, and then the light is guided to the front of the liquid crystal display through the reflector light guide plate. One is the direct type, that is, the light source is directly emitted from the back of the liquid crystal panel and directly shines on the liquid crystal panel. For the latter, the distance between the light source and the LCD panel needs to be more than 15mm, and the surroundings need to transition with a slope of 45 degrees. All LCD panels have PCB boards connected to them through flexible cables to realize photoelectric conversion. The PCB board on th...

Problems solved by technology

[0004] The biggest disadvantage of the first two methods is that the PCB board and the cavity slope are completely integrated, while the liquid crystal panel and the cavity need to have a gap, and there can be a certain amount of activity in the cavity. When the product is in the process of transportation, the liquid crystal panel When moving horizontally, the PCB board cannot follow the movement, causing the LCD panel and the PCB board to be forcibly pulled through the flexible cable, resulting in the loosening of the LCD panel flexible cable, and the product cannot work normally

As for the way of viscose, as time goes by, there is a hidden danger of falling off, which will affect the product quality
