[0010] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0011] The utility model provides Figure 1-2 A double-sided adhesive fixing structure for alleviating stress and light leakage of an IPS screen is shown, comprising an LCD screen;

[0012] Specifically, the LCD screen is rectangular, and each corner and bottom of the LCD screen is fixedly connected to a fixed structure, and the fixed structure includes double-sided tape and flexible PET. The double-sided tape is specifically pasted on the upper and lower surfaces of the flexible PET in an offset manner, wherein the double-sided tape on the upper side of the flexible PET is fixedly connected to the inner upper surface of the flexible PET, and the double-sided tape on the lower side of the flexible PET is fixedly connected to the outer lower surface of the flexible PET, and the corners of the LCD screen are press-fitted to the backlight panel through the fixed structure.

[0013] Specifically, the flexible PET is bent in the dislocation gap of the double-sided adhesive.

[0014] Working principle:

[0015] The flexible PET of this fixed structure is connected to the LCD screen and the backlight panel respectively through double-sided tapes that are offset up and down, and the offset empty position on the flexible PET can be bent up and down. After the fixed structure is pressed, the LCD screen is adhered to the double-sided tape on the inner side of the upper surface of the flexible PET, and the backlight panel is adhered to the outer side of the lower surface of the flexible PET. The offset position of the flexible PET is filled with blank gaps by bending. When the lower surface of the LCD screen or the upper surface of the backlight panel is uneven, this fixing method can effectively solve the light leakage problem and greatly improve the product yield.
