Description

Technical Field

[0001] This utility model relates to the field of screen technology, and in particular to a non-adhesive screen and terminal device. Background Technology

[0002] Traditional screen mounting methods include using tape, brackets, etc. For example, Chinese patent CN101998798A describes a detachable screen mounting structure that connects a screen and a base, allowing the screen to be quickly and easily fixed to or removed from the base. Utility model patents address screen mounting using brackets but do not involve the mounting technology of the screen itself or touchscreens. Chinese patent CN104238255A describes a screen mounting method that uses several steps—environmental cleaning, screen surface cleaning, fixing, pressing, and cutting—to secure the screen to a frame. Screens mounted this way can be made thinner, reducing footprint. Furthermore, using adhesive strips to fix the screen eliminates concerns about damage during the mounting process. However, the mounting process creates an air layer within the screen, causing light refraction, affecting display quality, and resulting in unclear images. During use, dust can easily accumulate, and the screen may detach, affecting its lifespan and display quality. The overall screen structure is also relatively thick, which is not conducive to the trend of lightweight devices.

[0003] With users' increasing demand for ultra-thin, high-definition display screens, as well as their growing requirements for convenient manufacturing processes and environmental awareness, there is an urgent need to develop a new screen to address current shortcomings and deficiencies. Utility Model Content

[0004] In view of this, the main purpose of this utility model is to provide a non-adhesive screen and terminal device that can achieve the purpose of securing the screen. At the same time, because it is non-adhesive, it is easy to disassemble, convenient to maintain, and easy to recycle.

[0005] To achieve the above objectives, as a first aspect of this utility model, a non-adhesive screen is proposed, comprising a touch screen, an outer frame with a placement slot for placing the touch screen, a middle frame disposed inside the outer frame for fixing the touch screen, and a display screen disposed inside the middle frame. The outer frame and the middle frame have screen connection holes on their side edges, which cooperate with screen fixing holes on the side of the display screen to secure the display screen. The upper and lower frame edges of the outer frame and the middle frame have frame connection holes for securing the outer frame and the middle frame.

[0006] In a second aspect, this utility model provides a terminal device that uses the aforementioned adhesive-free screen for display.

[0007] Based on the above technical solution, it can be seen that the technical solution of this utility model has at least one of the following beneficial effects compared with the prior art: The more compact structure reduces air gaps, thereby improving the screen's durability and structural strength. The adhesive-free screen's structural design reduces the use of adhesives and sealing materials, making the installation process simple and quick. This effectively improves installation efficiency, shortens installation time, reduces installation costs, and makes the screen easier to disassemble and dispose of during recycling. It avoids the scattering and absorption of light by the adhesive material, allowing the screen to display brighter, clearer, and more natural images and text, enhancing the user's visual experience; it will not cause color deviation or color difference problems due to the interaction between the adhesive material and the screen, and can more accurately restore the original colors of images and videos, ensuring color saturation and accuracy, making the displayed content more realistic and vivid; Unaffected by issues such as aging or deterioration of adhesive materials, it can maintain stable performance and display effects under different environmental conditions, such as environments with large variations in temperature and humidity, thus extending the screen's lifespan, reducing the risk of malfunctions and damage caused by environmental factors, and improving the screen's reliability and durability.
