Abstract
Description
Technical Field
[0001] This utility model relates to the field of edge light shielding technology for display modules, and more specifically, to an edge light shielding component for display modules that prevents light leakage. Background Technology
[0002] In existing display technologies, display modules typically consist of a backlight and an LCD display module. The backlight provides background illumination, while the LCD display module displays images. Light leakage issues arise not only from insufficient tightness at the connection between the screen and the bezel, but also from excessively strong light sources in the backlight module causing side leakage. This results in light escaping from the connection between the display and the phone's bezel, causing light leakage at the screen edges. Light leakage not only affects the product's aesthetics but can also, in severe cases, impact usability.
[0003] Chinese patent application CN202122408581.0 discloses a light leakage prevention display screen, comprising a display component, a backlight module, and a back panel stacked sequentially. The edges of the backlight module are wrapped with elastic light leakage prevention components, which cover the edges of the display component, the backlight module, and the back panel. This invention, by using elastic light leakage prevention components and foam strips, creates a relatively sealed space around the display component, backlight module, and back panel, effectively preventing side leakage of the light source.
[0004] However, as can be seen from the accompanying drawings in the instruction manual, the light-shielding film is wrapped around the foam strips located at the edge of the display module and the top and bottom sides of the display module. It can only buffer and protect the sides of the display module from light through the foam strips, but cannot buffer the top and bottom sides of the display module. Furthermore, when the light-shielding film is damaged due to wear at the top and bottom sides of the display module, it will affect the light-shielding effect. Therefore, a light-shielding component for the edge of the display module to prevent light leakage is proposed. Summary of the Invention
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a light-blocking component for the edge of a display module to prevent light leakage, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a light-blocking component for the edge of a display module to prevent light leakage, comprising a support frame disposed on a housing, wherein a display module and a backlight module are disposed in the middle of the support frame, and the support frame wraps and supports the display module and the backlight module. A support platform is fixedly connected to the middle of the support frame, thereby improving the support stability of the display module. A positioning groove is provided on the bottom outer surface of the support frame. A first light-blocking film is symmetrically pasted around the top perimeter of the backlight module. The positioning groove improves the stability of the support frame and the first light-blocking film can block the gap between the backlight module and the display module, thereby preventing light leakage.
[0007] The display module is symmetrically wrapped with a second light-shielding film. A light-shielding adhesive is provided on the outside of the second light-shielding film. A light-shielding bottom film is provided at the bottom of the light-shielding adhesive, and a light-shielding top film is provided at the top of the light-shielding adhesive. By wrapping the display module with the second light-shielding film, light leakage can be prevented from occurring around the display module, and the sealing performance of the display module can be improved. Furthermore, the combination of the light-shielding adhesive, the light-shielding top film, and the light-shielding bottom film increases the strength of the wrapping around the display module, preventing wear and tear from affecting the light-shielding effect. The light-shielding adhesive, located between the second light-shielding film and the light-shielding bottom film, can support and protect the display module when it is placed, and also cushion the display module, thus playing a role in shock absorption and protection.
[0008] Preferably, the display module is disposed on top of the backlight module, and the top of the first light-shielding film is fixedly connected to the bottom wall of the light-shielding bottom film. The first light-shielding film blocks the light from the gap at the side edge between the display module and the backlight module, thus preventing light leakage.
[0009] Preferably, one end of the light-shielding bottom film is fixedly connected to the bottom wall of the display module, and one end of the light-shielding adhesive is located outside the top of the light-shielding bottom film. The bottom end of the light-shielding adhesive is wrapped by the light-shielding bottom film to improve the stability of the bottom end of the light-shielding adhesive. The bottom end of the light-shielding top film covers the top end of the light-shielding bottom film, further improving the light-shielding effect on the edge of the display module and improving the light leakage prevention effect.
[0010] Preferably, the light-shielding adhesive is wrapped around the outside of the second light-shielding film, the display module is set on the top of the support platform, and the bottom wall of the light-shielding bottom film is attached to the top wall of the support platform. By using the light-shielding adhesive, the light-shielding top film, and the second light-shielding film on top of the display module, the light-shielding intensity is increased, the light-shielding thickness is increased, and the anti-wear effect is enhanced.
[0011] Preferably, the cross-sectional shape of the light-shielding adhesive is set to "U" shape, and the cross-sectional shape of the second light-shielding film is set to "U" shape. The light-shielding adhesive improves the wrapping effect and prevents light leakage. At the same time, the thickness of the light-shielding adhesive can increase the anti-collision effect around the display module and improve the protection effect.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model first improves the wrapping effect by using light-shielding adhesive, which also prevents light leakage. At the same time, the thickness of the light-shielding adhesive can increase the anti-collision effect around the display module and improve the protection effect. The second light-shielding film wraps around the display module, which can prevent light leakage around the display module and improve the sealing of the display module. In addition, the combination of light-shielding adhesive, light-shielding top film and light-shielding bottom film increases the strength and thickness of the wrapping around the display module, and prevents the light-shielding effect from being affected by wear.
[0014] 2. This utility model also uses a first light-shielding film to shield the gap between the side edges of the display module and the backlight module to prevent light leakage. The light-shielding adhesive is located between the second light-shielding film and the light-shielding bottom film, which can support and protect the display module when it is placed, and also buffer the display module to play a shock-absorbing and protective role.
[0015] In summary, through the interaction of the above-mentioned multiple functions, the light-shielding thickness can be increased while the display module is shielded from the light. This provides cushioning and shock absorption when the display module is placed, and prevents wear and tear on the top and bottom sides of the display module from affecting the light-shielding effect, thereby improving the light leakage prevention effect.
