Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a liquid crystal display screen capable of rapidly releasing surface static electricity. Background Art

[0002] The liquid crystal display is a flat, thin display device composed of a certain number of color or black and white pixels. It is placed in front of a light source or a reflective surface. It is a type of flat-panel display used for television and computer screen displays. The advantages of this display are low power consumption, small size, and low radiation.

[0003] In the actual product use environment of LCD screens, especially in industrial environments, there is a lot of electromagnetic interference, and LCD screens are products that are susceptible to interference. When products are subject to electromagnetic interference, they will produce abnormal phenomena such as multiple displays and crosstalk. These situations seriously affect the use of terminals, especially in industrial environments, where incorrect displays will lead to incorrect controls, resulting in serious consequences such as production accidents.

[0004] To address this problem, in the prior art, such as the patent document with application number CN202221439349.1, an antistatic structure of a liquid crystal display is disclosed. Antistatic bodies are arranged on all sides to form electrostatic release areas on all sides, thereby effectively releasing static electricity. The antistatic bodies are directly arranged on the glass substrate of the liquid crystal display without being connected to the pins. The structure is simple, and the production difficulty and cost are reduced. The first antistatic component and the second antistatic component arranged at its two ends are combined with the relatively arranged tip portions to form an autonomous tip discharge, and the static electricity is released through the tip portion at the gap, thereby forming an antistatic effect.

[0005] However, the technical solution disclosed in the above patent document still has limitations in use, because static electricity is everywhere, and the surface of the glass is prone to accumulate static electricity. If the static electricity is not discharged in time, it will form an electric field in the upper and lower ITO layers in the LCD box, causing the liquid crystal to flip at an angle, showing a bottom shadow, and even when the static electricity intensity is high, it is easy to damage the driver IC or the ITO wiring on the glass, resulting in damage to the LCD module.

[0053] A display screen main body 1, on which a conductive region is provided;

[0054] A metal layer 2, arranged in the conductive region, and the metal layer 2 can guide the conduction of static charges on the display screen main body 1;

[0056] When the liquid crystal display screen is in use, the metal layer 2 can guide the static charges accumulated on the display screen main body 1 to the guiding member 3, and then the guiding member 3 will export the static charges conducted by the metal layer 2.

[0057] In some specific embodiments, the display screen main body 1 includes a first substrate 4, a second substrate 5 is provided on one side surface of the first substrate 4, and the metal layer 2 is provided on the other side of the first substrate 4;

[0058] The metal layer 2 and the second substrate 5 are both provided with a polarizer 6 on the surface of the side away from the first substrate 4 .

[0059] In some specific embodiments, the conductive area is arranged along the edge of the display screen body 1, and the metal layer 2 is arranged as a closed structure in the conductive area, and a display area 7 is formed in the closed structure.

[0060] In some specific embodiments, a connecting member 8 is provided on a surface of the substrate 1 4 on one side close to the substrate 2 5 , and the guide member 3 is connected to the connecting member 8 .

[0061] In some specific embodiments, the length of substrate 1 4 is greater than the length of substrate 2 5 .

[0062] In some specific embodiments, the guide member 3 includes a connecting member 9, a flexible board 10, a flexible board 2 11 and a flexible board 3 12, which are arranged on the surface of the substrate 1 4 away from the substrate 2 5. The flexible board 10 and the flexible board 2 11 are both arranged on the surface of the substrate 1 4 away from the substrate 2 5 and are both connected to the metal layer 2 through the connecting member 9.

[0063] Flexible board three 12 is arranged on a side surface of substrate one 4 close to substrate two 5 and its end is connected to connector 8. Flexible board one 10, flexible board two 11 and flexible board three 12 are connected at an end away from substrate one 4 and merged into an end point to form an external connection end.

[0064] Please refer to Figure 3 and Figure 4 As shown, the flexible circuit board bound to the liquid crystal screen is divided into three parts, among which the flexible board 10 and the flexible board 2 11 are two binding PADs (i.e., connecting parts 9, PAD is a prior art related to flexible printed circuit boards, mainly used to connect the flexible board 10 with the flexible board 2 11 and the metal layer 2) bound to the substrate 1 4 by heat pressing. The two have the same function, and are connected to the molybdenum aluminum molybdenum metal ring (i.e., metal layer 2, not limited to molybdenum aluminum molybdenum metal rings, but also copper, aluminum, tin, etc. can be selected to be connected to the substrate 1 4 by electroplating. Generally speaking, the substrate 1 4 is a glass substrate) on the upper surface of the substrate 1 4, and one FPC (i.e., flexible board 10 and flexible board 2 11) is bound to the left and right to improve the reliability of the connection between the metal ring and the FPC. For example, if the FPC on one side is blocked or broken, the FPC on the other side can still achieve functional conduction. The flexible board 3 12 is heat pressed and bound to the bottom surface of the substrate 1 4, on the same side as the driver IC (i.e., connecting part 8). The flexible board 1 10 , the flexible board 2 11 and the flexible board 3 12 are finally integrated into one and connected to the terminal device.

[0065] In short, a circle of metal molybdenum aluminum molybdenum is electroplated on the surface of the LCD screen glass, and the metal molybdenum aluminum molybdenum is connected to the VSS of the terminal application device through the FPC. When the surface of the LCD screen is affected by static electricity, the static electricity will be directed to the ground in time through the circle of metal on the surface of the LCD screen to prevent static electricity from accumulating on the LCD screen and affecting the normal display effect of the LCD screen.

[0066] Example 4

[0067] The liquid crystal display screen capable of quickly releasing surface static electricity provided in the above embodiments is further optimized, and a gap exists between the edge of the conductive area and the edge of the display screen body 1, and the connecting member 9 is arranged in the gap.

[0068] In some specific embodiments, the size of the polarizer 6 is not larger than the size of the substrate 2 5 .

[0069] In some specific embodiments, the thickness of the metal layer 2 is not less than the thickness of the flexible board 10 .

[0070] In some specific embodiments, the thickness of the connecting member 8 is no greater than 1 / 2 of the thickness of the substrate 2 5 .

[0071] Since the basic operation process of the utility model is: electroplating a circle of metal molybdenum aluminum molybdenum on the surface of the LCD screen glass, the metal molybdenum aluminum molybdenum is connected to the VSS of the terminal application device through the FPC. When the surface of the LCD screen is affected by static electricity, the static electricity will be directed to the ground in time through the circle of metal on the surface of the LCD screen to avoid static electricity accumulation on the LCD screen and affect the normal display effect of the LCD screen. In this process, the connecting piece 9 is set in the gap to prevent the edge of the connecting piece 9 from exceeding the edge of the display screen body 1, resulting in the overall installation being affected.

[0072] The size of the polarizer 6 is set to be no larger than the size of the substrate 2 5 in order to prevent the edge of the polarizer 6 from exceeding the substrate 2 5 , thereby preventing the edge of the polarizer 6 from being scratched against the flexible board 3 12 .

[0073] The thickness of the metal layer 2 is not less than the thickness of the flexible board 10 in order to prevent the polarizer 6 and the connecting piece 9 from moving relative to each other.

[0074] The thickness of the connecting member 8 is not greater than 1 / 2 of the thickness of the substrate 2 5 in order to prevent the connecting member 8 from being too thick, which may cause the flexible board 3 12 to be lifted up when connected to the flexible board 3 12, causing the flexible board 3 12 to be scratched against the substrate 1 4.
