Detailed Description
The technical solution of the present invention is further described by the specific embodiments with reference to fig. 1 to 6.
In the present invention, the narrow border refers to a narrow black border.
The embodiment of the invention provides a first embodiment of a structure of narrow frames on two sides of a mobile phone touch screen.
As shown in fig. 2 and 5, the structure of the narrow frames on the two sides of the touch screen of the mobile phone comprises a display module, wherein the display module comprises a touch screen (TP)2, COG liquid crystal glass 4 and a backlight support 6, the COG liquid crystal glass 4 is arranged below the touch screen 4, the backlight support 6 is arranged below the COG liquid crystal glass 4, and the two sides of the COG liquid crystal glass 4 are flush with the two sides of the backlight support 6.
In this embodiment, both sides of the backlight bracket 6 and both sides of the COG liquid crystal glass 4 refer to both sides in the width direction. The two sides of the width of the backlight support 6 are parallel and level with the two sides of the width of the COG liquid crystal glass 4, the width of the two sides of the narrow frame A of the two sides of the mobile phone touch screen is reduced, and the screen occupation ratio is improved.
Preferably, the COG liquid crystal glass 4 is attached to the touch screen 2 through OCA glue 3, the COG liquid crystal glass 4 is placed in the middle of the touch screen 2, and the COG liquid crystal glass 4 is symmetrically arranged on the center line of the touch screen 2 in the width direction along the width direction. A screen backlight film 5 is arranged between the COG liquid crystal glass 4 and the backlight support 6, the COG liquid crystal glass 4 is fixedly connected with the backlight support 6 through glue 12, two sides of the bottom surface of the backlight support 6 of the display module are fixedly connected with an injection molding steel sheet 7 in the shell mold through double faced adhesive/foam plastic 13, and the width of the adhesive of the double faced adhesive/foam plastic 13 can be flexibly adjusted according to the requirement, such as widening or narrowing.
Preferably, the width of the touch screen 2 is smaller than the width of the COG liquid crystal glass 4, so that the width of the narrow frames a on the two sides of the mobile phone touch screen can be directly reduced, and the width of the narrow frames a can be flexibly adjusted according to the width of the touch screen 2, as shown in fig. 5. Preferably, decorating parts 8 are arranged on two sides of the touch screen 2, the lower surface of each decorating part 8 is connected with the case 1 through dispensing/foam adhesive 9, and foam 10 is arranged between the lower surface of each decorating part 8 and the COG liquid crystal glass 4.
Because the width dimension of touch-sensitive screen 2 will be less than COG liquid crystal glazing 4's width dimension, in order to solve the problem that COG liquid crystal glazing 4's both sides expose and lead to the outward appearance not pleasing to the eye, this embodiment is provided with decoration 8 in touch-sensitive screen 2's both sides, utilize decoration 8 to push down the exposed part of COG liquid crystal glazing 4 both sides, this decoration can do various different ID process design, can enrich the ID design thinking of cell-phone product, make the positive ID design of cell-phone more nimble and diversified, can change the problem of the positive ID design homogenization of current cell-phone greatly.
The lower surface of the decoration piece 8 is connected with the shell 1 through glue dispensing/foam adhesive 9, and when the width of the decoration piece 8 designed on the ID is narrower, the decoration piece is connected with the shell 1 in a glue dispensing mode; when the width of the decoration 8 on the ID design is wider, it is adhered to the cabinet 1 by means of foam adhesive or double-sided adhesive. Of course, depending on the design of the ID, the ID may be fixed by injection molding or the like together with the housing 1. Foam 10 is arranged between the lower surface of the decoration 8 and the COG liquid crystal glass 4, the COG liquid crystal glass 4 can be pressed auxiliarily by the foam 10, and the decoration 8 can be prevented from crushing the glass of the COG liquid crystal glass 4.
Preferably, the side surface of the decoration 8 is connected with the casing 1, and the side surface of the decoration 8 is connected with the touch screen 2 through a sealant/buffer glue 11. The scheme solves the problems of dust entering, light leakage and the like caused by the gap between the decorating part 8 and the shell 1 and between the decorating part 8 and the touch screen 2. The better compressibility and elasticity of the sealant/cushion rubber 11 can ensure the sealing dustproof requirement and the shading requirement of the casing 1 and the decorating part 8 on the display module, and the sealant/cushion rubber has certain falling buffering capacity and has a protection effect on the display module.
The embodiment of the invention provides a second embodiment of a structure of narrow frames on two sides of a mobile phone touch screen.
Unlike the first embodiment, the width dimension of the touch screen 2 is larger than that of the COG liquid crystal glass 4, and therefore, the decorative member 8 is eliminated, as shown in fig. 3 and 6, and the design is very flexible.
Preferably, the touch screen 2 is connected with the casing 1 through a sealant/buffer glue 11, as shown in fig. 6. The sealant/buffer glue 11 in this embodiment can solve the problems of dust entering, light leakage and the like caused by the gap between the touch screen 2 and the casing 1, and the better compressibility and elasticity of the sealant/buffer glue 11 can ensure the sealing dustproof requirement and the shading requirement of the casing 1 and the touch screen 2 on the display module, and has certain buffer capacity and a protection effect on the display module.
In summary, by adopting the structural design that the two sides of the COG liquid crystal glass 4 are flush with the two sides of the backlight support 6, the width of the narrow frame a on the two sides of the mobile phone touch screen can be reduced no matter the width of the touch screen 2 is smaller than the width of the COG liquid crystal glass 4 or the width of the touch screen 2 is larger than the width of the COG liquid crystal glass 4. And when the width dimension of the touch screen 2 is smaller than that of the COG liquid crystal glass 4 and the decorating parts 8 for pressing the exposed part of the COG liquid crystal glass 4 are arranged on the two sides of the touch screen 2, the structure can enable the width of the narrow frames A on the two sides of the touch screen to meet various ultra-narrow dimension requirements and even achieve the width dimension with narrow limit.
