The profile middle frame 2' and the back plate 1' are bonded and fixed by glue, and a gap needs to be reserved between the profile middle frame 2' and the back plate 1' to prevent assembly failure due to part tolerance. The profile middle frame 2' and the light guide plate 52' have overlapping areas to prevent the light guide plate 52' from leaning forward or detaching from the profile middle frame 2' in an inclined state, resulting in side light leakage, poor visual effects, and fragmentation of the display panel 3'. There is an assembly gap between the front and the back of this structural form, which affects the overall aesthetic feeling, and the overall strength is relatively poor.

There is no overlapping area between the profile middle frame 2' and the light guide plate 52', and the cushion pad 6' is used to squeeze and fix the end surface to prevent The light guide plate 52' jumps out. In contrast, this structural method is conducive to reducing the thickness of the module, but the same as the previous form, there is an assembly gap between the front and the back, which affects the overall aesthetics, and the overall strength is slightly weaker.

detailed description

In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

As shown in FIG. 3 and FIG. 4 , the ultra-thin side-entry liquid crystal module provided in this embodiment includes a backplane 1 , a middle frame 2 , a display panel 3 , an optical component 5 , and a light bar. A light source, generally an LED lamp bead, is provided on the light bar as an initial light source. The optical component 5 converts the light from the initial light source into a surface light source. The liquid crystal module of this embodiment is a side-entry type liquid crystal module. Therefore, the thickness of the side-type LCD module is thinner than that of the direct-type LCD module. The optical assembly 5 may include a reflective sheet 51 , a light guide plate 52 and an optical film 53 arranged sequentially from the back to the front, and the light emitting surface of the light bar is arranged opposite to the side of the light guide plate 52 . The light emitted by the light source on the light bar enters along the side of the light guide plate 52, part of it is totally reflected by the light guide plate 52, and then exits from the light emitting surface of the light guide plate 52, and the other part is reflected from the light guide plate 52 after being reflected by the reflector 51. The light is emitted from the light-emitting surface, and the light is gradually mixed evenly in the process to form a surface light source. The light emitted from the light guide plate 52 is further adjusted by the optical film 52 to form a relatively uniform surface light source. The middle frame 2 encloses an accommodating space, and the optical assembly 5 and the light bar are accommodated in the accommodating space, and the light bar is located between the side of the optical assembly 5 and the inner wall of the middle frame 2 . The optical component 5 and the light bar are protected by the middle frame 2 in the inner accommodation space. The middle frame 2 is bonded to the front of the backplane 1 , and the back of the middle frame 2 is covered by the backplane 1 . The display panel 3 is bonded to the front of the middle frame 2 , and the front of the middle frame 2 is covered by the display panel 3 . The display panel 3 generally includes upper and lower polarizers, a liquid crystal layer, and a driver integrated circuit. The display panel 3 forms corresponding images or pictures by controlling the passing position and amount of light emitted from the optical component 5 .

The ultra-thin side-entry liquid crystal module of this embodiment uses the back plate 1 and the display panel 3 to cover the front and back of the middle frame 2 respectively, eliminating the gap between the front and the back of the liquid crystal module, and there is no gap caused by uneven gap. The problem is that the way of bonding is also convenient for assembly, which is conducive to automatic assembly and improves assembly efficiency. In addition, after the display panel 3 covers the middle frame 2, a floating visual effect can be formed.

The back plate 1 of this embodiment is made of toughened glass, which has the advantages of high strength and good rigidity, and is more beautiful, and the appearance treatment methods, types, and effects are more diverse. Compared with traditional metal materials, not only in terms of structure but also Both have advantages in appearance.

In this embodiment, the outer edge shapes of the backplane 1, the middle frame 2, and the display panel 3 are the same, for example, they are all set in a rectangular shape, which is convenient for the middle frame 2, the backplane 1, and the display panel 3 to fit together without causing Larger edge distance errors. In this embodiment, the area of the backplane 1 is larger than the area of the display panel 3 to form a stepped structure. The stepped structure can displace the backplane 1 and the display panel 3 in space, more clearly reflecting the ultra-thin visual Effect.

In this embodiment, the light guide plate 52 may be a common light guide plate, such as an acrylic light guide plate, or a glass light guide plate. In order to prevent the optical assembly 5 from leaving the accommodating space, a buffer pad 6 is provided between the side of the light guide plate 52 and the inner wall of the middle frame 2, and the light guide plate 52 and the middle frame 2 respectively press the buffer pad 6 from both sides to keep relatively fixed .

The middle frame 2 can be made of profiles, such as aluminum profiles, etc., which have relatively high structural strength and are relatively light. The back panel 1 and the middle frame 2 can be glued together, and the glue is convenient to dispense, and the glue can be dispensed by a glue dispenser. The display panel 3 and the middle frame 2 can be bonded by the foam double-sided adhesive 4 , the foam double-sided adhesive has strong adhesion, good retention, good waterproof performance, strong temperature resistance, and strong UV protection ability.

The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. limits.
