Description

Technical Field

[0001] The utility model belongs to the technical field of IPS screen light leakage prevention, and in particular relates to a double-sided adhesive fixing structure for alleviating stress-induced light leakage of an IPS screen. Background Art

[0002] IPS screen is a technology based on TFT, and its essence is TFT screen. In the display module industry, the IC end of IPS wide-viewing angle liquid crystal film group often has problems with glass or backlight flatness, which leads to uneven force on LCD and light leakage, resulting in poor display effect. In response to this, a double-sided adhesive fixing structure is introduced to alleviate the light leakage of IPS screen, solve the problem of light leakage caused by uneven force, and improve the product yield. Utility Model Content

[0003] The utility model aims to provide a double-sided adhesive fixing structure for alleviating the light leakage caused by the stress on the IPS screen, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-sided adhesive fixing structure for alleviating light leakage of an IPS screen under stress, comprising an LCD screen, wherein the LCD screen is specifically rectangular, and each corner and bottom of the LCD screen is fixedly connected with a fixing structure, wherein the fixing structure comprises double-sided adhesive and flexible PET, and the double-sided adhesive is specifically pasted on the upper and lower surfaces of the flexible PET in an offset manner, wherein the double-sided adhesive on the upper side of the flexible PET is fixedly connected to the inner upper surface of the flexible PET, and the double-sided adhesive 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 with the backlight panel through the fixing structure.

[0005] Preferably, the flexible PET is bent within the dislocation gap of the double-sided adhesive tape.

[0006] The technical effects and advantages of the utility model are as follows: the flexible PET of the fixed structure is connected to the LCD screen and the backlight panel by using double-sided adhesive tape that is offset up and down, and the staggered part of the flexible PET of the connecting part can be bent up and down to balance the uneven force problem caused by the uneven surface of the bottom of the LCD screen or the backlight panel, thereby solving the light leakage problem. The structure is simple, the operation is portable, and the product yield is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 This is a schematic diagram of the structure of the fixed structure of the utility model before pressing;

[0008] Figure 2 It is a schematic diagram of the structure of the utility model after the fixed structure is pressed.

[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.
