Example Embodiment

[0029] Example 1:

[0030] Such as figure 1 with figure 2 As shown, the curved screen installation structure includes an outer frame 1, a display screen 2, and a rubber ring 3; the outer frame 1 is a ring structure adapted to the outline of the display screen 2, and the top of the outer frame 1 is a fixed surface 101 and a rubber ring 3. Fixed on the fixed surface 101; the top of the rubber ring 3 is provided with a hot-melt adhesive receiving groove 301, the hot-melt adhesive receiving groove 301 extends along the top of the rubber ring 3 one week; the display screen 2 includes a flat portion 201 and the edge of the flat portion 201 The arc-shaped portion 202 extends outward, the bottom of the arc-shaped portion 202 is attached to the top of the rubber ring 3, and the bottom of the arc-shaped portion 202 completely covers the hot melt adhesive receiving groove 301 and closes the hot melt adhesive receiving groove 301; The groove 301 is filled with hot melt glue 4; the bottom o...

Example Embodiment

[0034] Example 2:

[0035] Such as figure 2 According to this embodiment, on the basis of embodiment 1, the bottom cross section of the arc-shaped portion 202 is a circular arc surface A203; the top cross section of the rubber ring 3 is a circular arc surface matching the circular arc surface A203 B302.

[0036] The arc surface A203 and the arc surface B302 are provided to increase the contact area between the display screen 2 and the rubber ring 3, so that the display screen 2 is fixed more firmly.

Example Embodiment

[0037] Example 3:

[0038] Such as figure 2 According to this embodiment, on the basis of the first embodiment, the top outer edge of the rubber ring 3 is rounded to form a rounded surface A303; a gap is formed between the rounded surface A303 and the bottom of the arc portion 202 A304.

[0039] When the rubber ring 3 is deformed by an impact, the gap A304 provides space for deformation at the outer edge of the rubber ring 3 to prevent the rubber ring 3 from directly squeezing the display screen 2 when the rubber ring 3 is deformed by the impact, and prevents the display screen 2 from being damaged under pressure.

Abstract

The invention discloses a curved screen installation structure; the outer frame is a ring structure adapted to the outline of the display screen, the top of the outer frame is a fixed surface, and a rubber ring is fixed on the fixed surface; the top of the rubber ring is provided with hot melt adhesive The accommodation groove, the hot melt adhesive accommodation groove extends for a week along the top of the rubber ring; the display screen includes a flat portion and an arc portion extending outward along the edge of the flat portion, the bottom of the arc portion is attached to the top of the rubber ring, and the arc portion The bottom completely covers the hot melt adhesive storage tank and closes the hot melt adhesive storage tank; the hot melt adhesive storage tank is filled with hot melt adhesive; the bottom of the hot melt adhesive storage tank is evenly opened with multiple holes for the hot melt adhesive to pass through under pressure The diameter of the vertical blind hole is 1 mm; the rubber ring is provided with a cavity connected to the bottom of the vertical blind hole for containing the hot melt adhesive from the vertical blind hole. The invention prevents the impact force from being directly transmitted to the display screen to cause damage to the display screen, and improves the impact resistance of the display screen. The invention has high manufacturing efficiency.

Description

technical field [0001] The invention relates to an image display device. Background technique [0002] In the manufacturing process of mobile terminals, especially mobile phones, the screen is directly assembled on the outer frame. The assembly process is to place hot melt adhesive on the upper surface of the outer frame at intervals, then press the screen on the outer frame, and bond the screen and the outer frame with hot melt adhesive. [0003] The disadvantage of installing the screen in this way is that the screen is in direct contact with the outer frame, and the impact force on the outer frame will be directly transmitted to the screen, causing the screen to break. Especially when the outer frame is made of metal materials, the screen will not have any buffer protection under impact, and the screen is easily damaged during use. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cur...
