Technical Field

The application relates to the technical field of displays, in particular to a display.

Background

As consumer demand for the appearance of electronic products increases, the bezel of displays such as lcd televisions becomes narrower. To meet the narrow bezel requirements of displays, the black edge width of liquid crystal glass is also gradually reduced, for example, the black edge of mainstream displays is 5mm, and the black edge of high-end displays is 3mm or even 0.9mm. The narrower the black edge width of the liquid crystal glass is, the smaller the size of the support bar for supporting the display panel is, so that the connection and fixation of the support bar and the backboard are more problematic.

Referring to fig. 21, fig. 21 is a schematic cross-sectional view of another embodiment of the optical assembly shown in fig. 2. In some embodiments, the optical assembly 40 includes a display panel 41 and a diffusion plate 42, and a fixing cavity 420 for fixing the display panel 41 is formed on one side surface of the diffusion plate 42, so that the display panel 41 is fixedly connected with the diffusion plate 42.

In the prior art, the display panel 41 and the diffusion plate 42 of the optical assembly 40 are adhered and fixed by glue. However, the glue adheres to and fixes the display panel 41 and the diffusion plate 42, so that the brightness of the light beam passing through the optical assembly 40 is lost by about 10%. Taking liquid crystal electricity of the same optical specification as an example, the number of LEDs in the backlight assembly 50 needs to be increased by 10% or the power of the backlight assembly 50 as a whole is increased by 10%. Compared with the prior art, the embodiment provided by the application provides that the display panel 41 and the diffusion plate 42 are clamped and fixed, so that the brightness loss of light rays is reduced, the materials are saved, and the power consumption is reduced.

Referring to fig. 22, fig. 22 is a schematic cross-sectional view of the light guide assembly shown in fig. 2. The light guide assembly 60 may include a light guide 61 and a reflective sheet 62.

Optionally, the light guide 61 further includes a plurality of light scattering structures 610, and the light scattering structures 610 are disposed on the first surface 6111 and the third surface 6121, so that the light in the light guide 61 is diffusely reflected to uniformly irradiate on the diffusion plate 42.

Further, the light diffusing structure 610 may be a bump fixed on the light guide 61 to reflect the light in the light guide 61 to any angle. In other embodiments, the light scattering structure 610 may be a pit formed on the light guide 61 or an ink dot printed on the surface of the light guide 61 for reflecting the light in the light guide 61. In other embodiments, the light diffusing structures 610 may also be a combination of bumps, pits, or ink dots.

Specifically, the reflective sheet 62 is provided with a first breaking line 6201 and a second breaking line 6202 which are arranged in parallel at intervals, the first breaking line 6201 and the second breaking line 6202 divide the reflective sheet 62 into a first area 621, a second area 622 and a third area 623 which are connected in a bendable manner, wherein the first area 621 corresponds to and is attached to the second surface 6112, the second area 622 corresponds to and is attached to the first surface 6111, and the third area 623 corresponds to and is attached to the third surface 6121, so that the reflective sheet 62 is fully attached to the light guide 61.

Further, the reflective sheet 62 is provided with yellow dots 620 on the area corresponding to the second surface 6112 and the first surface 6111. According to the light source complementation principle, blue light is white after being reflected by the yellow dots, and meanwhile, partial light can be absorbed and scattered by the yellow dots, so that the brightness of the reflected light is reduced, and the phenomenon that blue bright frames appear at the edge of a liquid crystal display screen using a blue LED direct type backlight module due to a short light mixing distance can be effectively improved, so that the optical taste is improved, and the display effect is improved.

The display 100 provided by the application can be clamped and connected with the first clamping part 201 through the first matching part 301 to limit the support bar 30 to move along the first direction relative to the backboard 20, and the second matching part 302 can be clamped and connected with the second matching part 302 to limit the support bar 30 to move along the second direction relative to the backboard 20, so that on one hand, the support bar 30 is more firmly connected with the backboard 20, and on the other hand, the support bar 30 is convenient to detach from the backboard 20. In addition, the light guide assembly 60 is disposed between the support bar 30 and the optical assembly 40, so that the black side of the display screen is smaller.

The foregoing description is only a partial embodiment of the present application, and is not intended to limit the scope of the present application, and all equivalent devices or equivalent process transformations made by using the descriptions and the drawings of the present application, or direct or indirect application to other related technical fields, are included in the patent protection scope of the present application.
