Display device

Abstract

The invention discloses a display device. The display device comprises an outer frame, a sheet metal part and a display panel, the outer frame comprises a bottom plate and a side plate surrounding the bottom plate, and a cavity is defined by the bottom plate and the side plate; the sheet metal part is arranged in the cavity, and one end of the sheet metal part is embedded into the bottom plate; and the display panel is arranged in the cavity, and the edge of the display panel is arranged on the surface of the side, away from the bottom plate, of the sheet metal part. The display device has the beneficial effects that the sheet metal part is adopted for bearing the display panel, the flatness of the display panel can be guaranteed, the outer frame is made of the die casting, higher strength is achieved, the service life of the display device is prolonged, and the sheet metal part is embedded into the outer frame and fixed through the fixing part, therefore, the matching stability of the sheet metal part and the outer frame is improved, the frame thickness of the display device is reduced, and the narrow frame requirement is met.

Description

technical field [0001] The present application relates to the field of backlight, in particular to a display device. Background technique [0002] At present, there are more and more designs of vehicle-mounted display screens as floating screens and rotating screens, and the size is getting larger and larger. The traditional sheet metal structure cannot meet the requirements of high strength and high reliability. Generally, die-casting parts will be used as the first choice to design the backlight. The display screen using die-casting parts not only provides higher strength, but also can design complex structural parts to enhance the assembly strength of the module and the whole machine. [0003] During the research and practice of the prior art, the inventors of the present application found that for the backlight design of die-casting parts, the plastic frame in the backlight is usually embedded into the die-casting part through buckles, but with the on-board display Reli...

Problems solved by technology

[0002] At present, there are more and more designs of vehicle-mounted display screens as floating screens and rotating screens, and the size is getting larger and larger. The traditional sheet metal structure cannot meet the requirements of high strength and high reliability. Generally, die-casting parts will be used as the first choice to design the backlight. The display screen using die-casting parts not only provides higher strength, but also can design complex structural parts to enhance the assembly strength of the module and the whole machine

[0003] During the research and practice of the prior art, the inventors of the present application found that for the backlight design of die-casting parts, the plastic frame in the backlight is usually embedded into the die-casting part through buckles, but with the on-board display Reliability requirements are getting higher and higher, especially the high and low temperature composite vibration is more and more important. In this embedded matching method, the compatibility between the plastic frame and the cast aluminum parts is poor, and it cannot be tightly fixed, and the load bearing of the panel cannot be guaranteed. The flatness of the surface, after the composite vibration test, it is easy to appear vibration white spots, film material breakage, uneven color and other undesirable phenomena

In the traditional plastic frame external card method, because the plastic frame is sandwiched between the module cover plate and the cast aluminum part, the fixed bonding surface between the cover plate and the backlight can only be bonded through the plastic frame, and the bonding reliability is not directly bonded to the die-casting part. The connection strength is high, and when using the traditional plastic frame outer card die-casting parts, the buckles of the die-casting parts cannot leak out, and the appearance parts of the customer's whole machine cannot be directly engaged with the display screen
