Description

Technical Field

[0001] The utility model relates to the technical field of display modules, and particularly relates to a display module for a mobile phone liquid crystal display screen. Background Art

[0002] The display module of a mobile phone liquid crystal display screen refers to the liquid crystal screen component used for displaying images and texts in a mobile phone. This component usually includes a liquid crystal panel, a backlight module, and some necessary connecting components. The liquid crystal panel is the core part of the display module, which is composed of two glass substrates and liquid crystal molecules sandwiched in the middle. The backlight module assembly: located behind the liquid crystal panel, provides a uniform light source. The backlight module usually includes components such as a light source (such as an LED lamp) and a light guide plate to ensure that the screen can be normally displayed under various light conditions.

[0003] Currently, an existing device (such as the publication number: CN208861986U) discloses an "LED display module". The device uses the setting of the first encapsulation structure to enclose and protect the light-emitting components. The flat surface of the first encapsulation structure can eliminate the influence of substrate warping. The setting of the second encapsulation structure can, on the one hand, protect the flat surface of the first encapsulation structure, and on the other hand, can adjust the light transmittance of the LED display module by installing different second encapsulation structures, thereby having a better display effect;

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: when the device is in use, since the LED lamp group will generate a large amount of heat during operation, it is difficult for the heat inside the device to dissipate after encapsulation, which is likely to cause the aging of the LED chip and the encapsulation material, resulting in increased light decay and shortened lifespan, and the practicability needs to be improved. Summary of the Utility Model

[0014] Preferably, an LCD screen is provided inside the plastic shell frame, and the LCD screen is located above the LED lamp group.

[0015] (III) Beneficial effects

[0016] First, by providing a special-shaped groove inside the LED panel and arranging a copper special-shaped part inside the special-shaped groove, the heat dissipated by the LED lamp group of the LED panel during operation can be guided to the copper connecting part through the copper special-shaped part for heat dissipation, thereby improving the practicability.
