Description

Technical Field

[0001] This utility model belongs to the field of liquid crystal display technology, and specifically relates to a mobile phone liquid crystal display with a heat dissipation structure. Background Technology

[0002] The LCD screen is an important component of a mobile phone. The main body of the LCD screen is made of two-stage materials with a liquid solution in between. When electricity is applied to the liquid, the crystals rearrange. With the continuous development of electronic products, the functions of mobile phone LCD screens have become more and more sophisticated, and modern mobile phones and screens are developing towards ultra-thin and widescreen designs.

[0003] The existing technology, patent publication number CN219936241U, describes a mobile phone LCD display with a built-in protective mechanism. By installing an explosion-proof film and an anti-scratch film on the top of the screen, it can provide good protection for the screen below in the event of a fall. Furthermore, the installation of the explosion-proof and anti-scratch films eliminates the need for a tempered glass screen protector. Additionally, the anti-light black border on one side of the explosion-proof and anti-scratch films effectively prevents light leakage. This addresses the issue of poor protection during use. However, in practical use, the following shortcomings remain: In reality, this display mostly relies on thermal silicone to dissipate heat, which is insufficient for timely and rapid heat dissipation. Excessive heat on the phone screen can easily cause damage, and the user experience is poor.

[0004] Therefore, a mobile phone LCD screen with a heat dissipation structure is needed to solve the problems of existing technologies that cannot dissipate heat in a timely and rapid manner, which can easily damage the mobile phone screen due to excessive heat and result in a poor user experience.
