Description

Technical Field

[0002] Mobile phone display module refers to a complete display unit that integrates display panel, touch panel, backlight module and other related components. Mobile phone display module is the core component of mobile phone screen, responsible for displaying all images and interface content, and providing touch interaction function for users. This module is usually composed of multiple sub-components to ensure display effect, touch response and overall performance.

[0003] After searching, it is found that in order to make the screen surface appear smoother and larger, the LCD display module in the prior art hides the front camera module inside the mobile phone, and pushes the front camera module out from the top or other position of the mobile phone when front-facing photography is needed. Although this method can keep the front of the screen smooth and without a camera at ordinary times, after long-term use, dust will inevitably accumulate at the gap at the exit of the camera, and the gap is inconvenient to clean. In the long run, the entry and exit of the camera will become less smooth, affecting the smoothness of use.

[0017] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of this application: 1. In order to solve the problem that the front camera in the prior art occupies the screen area and is easily infringed on the portrait right, the present application sets a lifting drive mechanism and a hidden front camera module adapted thereto, so that the front camera module can be hidden inside the top card cover when front-facing shooting is not required, and with a blowing head that can blow air toward the gap between the front camera module and the dust-proof duct, the dust blocking the gap can be cleaned from the inside to the outside in time while the front camera module is pushed out and retracted, effectively preventing blockage during entry and exit; 2.

When the mobile phone is used, if the corner is accidentally dropped to the ground, it will not cause through-type cracks on the surface of the mobile phone screen, and it plays a certain role in buffering and releasing stress concentration. Even if a destructive collision occurs, it will not cause the screen body to produce shattering cracks, but only cause the corners to break, so that the emergency use of the mobile phone will not be affected in a short time. 3. The concave slot and roughened light-blocking treatment process set on the side of the tempered glass, combined with the side guard tightly connected to the concave slot, can prevent the strip light on the side of the backlight module from emitting from the side, effectively preventing the occurrence of light leakage, and making the four sides of the tempered glass more tightly engaged, making it more difficult for dust to enter the interior; 4. Through such an arrangement, the blowing mechanism can be driven to operate while the lifting drive mechanism is started. Moreover, since the crankshaft journal radius becomes larger, the two piston air barrels can produce a larger stroke, thereby increasing the wind pressure and improving the dust removal effect. In addition to dust removal, the wind force can also dissipate heat for internal heat-generating parts. BRIEF DESCRIPTION OF THE DRAWINGS
