Description

Technical Field

[0001] The utility model relates to a liquid crystal screen, and more precisely, an InCell glass static electricity release component. Background Art

[0002] InCell refers to a method of embedding the touch panel function into liquid crystal pixels, that is, embedding the touch sensor function inside the display screen, which can make the screen thinner and lighter. However, for the existing liquid crystal screen with an InCell structure, its FPC is easily interfered by static electricity, affecting the display effect.

[0003] The Chinese utility model patent document CN214151663U discloses a design structure of an Incell broken code touch display screen ITO, which includes a touch screen, a touch control MCU, an active shielding trace, a signal transmission FPC cable, and a touch control signal trace. The touch screen includes an upper ITO glass, a lower ITO glass, and touch electrodes. The touch control MCU is soldered onto the PCB board by surface mounting. The touch control MCU is used to collect and process the magnitude of touch charges. The active shielding trace is connected to the pin of the touch control MCU after being connected in series with a 10KΩ chip resistor. The active shielding trace is mainly used to balance the touch charges and maintain the stability of collecting touch charges. The touch control signal trace is connected to the pin of the touch control MCU after being connected in series with a 1KΩ chip resistor. The signal transmission FPC cable is used to connect the touch screen and the touch control MCU. The upper ITO glass and the lower ITO glass are adhesively connected by frame glue around. On the inner side surfaces of the upper ITO glass and the lower ITO glass, Shield-Ground electrostatic shielding traces are sequentially arranged in a surrounding manner from the outside to the inside. On the lower surface of the upper ITO glass, there is a signal COM-ITO trace corresponding to the display pattern. On the upper surface of the lower ITO glass, there are an active shielding trace, touch electrodes, touch control signal traces, and a signal SEG-ITO trace corresponding to the display pattern. PI alignment films are adhesively bonded to the lower surface of the upper ITO glass and the upper surface of the lower ITO glass, and liquid crystal molecules are provided between the PI alignment films. An ITO conductive film is provided on the upper surface of the upper ITO glass, and there is a region without an ITO conductive film on one side of the upper surface of the upper ITO glass. A filter glass is provided on the upper surface of the ITO conductive film, and a cover glass is connected to the upper surface of the filter glass by OCR full lamination. The model of the touch control MCU is ATtiny1616. The signal transmission FPC cable uses a 10PIN cable. The gold fingers on the signal transmission FPC cable are welded and fixed on the lower ITO glass by a Bonding machine to connect the touch screen and the touch control MCU on the PCB board. The signal SEG-ITO trace corresponding to the display pattern is embedded in the touch electrode. The horizontal distance between the pads of adjacent touch electrodes is 7mm, and the vertical distance is 5.5mm. The designed size of the touch electrode is 14mm*10mm. Obviously, by simultaneously manufacturing both the touch electrodes and the working display pattern SEG-ITO traces on the upper surface of the lower ITO glass inside the liquid crystal screen and embedding the pattern of the touch display button in the area of the touch electrode, the use of a display board and a touch board is eliminated, the screen thickness is reduced, and the thinness and lightness of the screen display device are improved.By designing active shielding traces around the same side of the touch electrode area, connecting the touch signal and the active shielding trace signal to the touch MCU simultaneously through the signal transmission FPC cable, and applying the same signal waveform as the touch electrode to the active shielding trace by the touch MCU, the charge loss of the touch signal is inhibited and slowed down, interference is isolated and shielded, and the improvement of touch sensitivity is achieved. However, this structure cannot solve the existing electrostatic problems.

[0004] The Chinese utility model patent document CN201788332U discloses an anti-static liquid crystal display screen capable of accelerating electrostatic dissipation, which includes two mutually parallel glass substrates. Sealing glue is provided around the two glass substrates. The two glass substrates and the sealing glue are sealed to form a closed inner cavity. The closed inner cavity is filled with liquid crystal. ITO trace electrodes for displaying pixel patterns are provided on the inner sides of the two glass substrates. It is characterized in that: ITO conductive blocks for dissipating static electricity are filled in the blank areas on the inner sides of the two glass substrates, and a gap is provided between the ITO conductive blocks and the ITO trace electrodes. Polarizing films are attached to the outer sides of the two glass substrates. Pad materials are filled in the closed inner cavity formed by sealing the two glass substrates and the sealing glue. The ITO trace electrodes are connected with conductive electrodes. The thickness of the glass substrate is 0.3 - 1.1 millimeters. The ITO conductive blocks filled in these blank areas of this liquid crystal display screen can quickly conduct away and dissipate the accumulated charges, achieving the purpose of anti-static. However, this structure cannot solve the existing electrostatic problems. Utility Model Content

[0029] As described in the background art, for InCell glass in the prior art, InCell refers to a method of embedding the touch panel function into liquid crystal pixels, that is, embedding the touch sensor function inside the display screen, which can make the screen thinner and lighter. However, for the existing liquid crystal display screen with an InCell structure, its FPC is easily affected by electrostatic interference, which affects the display effect.

[0030] To solve this technical problem, the present utility model provides an InCell glass electrostatic discharge component, which includes an InCell glass body 1 and an FPC body 2. The InCell glass body 1 includes a glass surface ITO layer and a CF layer. The CF layer is located above the glass surface ITO layer. A CND ITO layer 11 is provided on the surface of the CF layer. The CND ITO layer 11 forms an electrical connection with the glass surface ITO layer, and the glass surface ITO layer forms an electrical connection with the FPC body 2.

[0031] Through the above structural design, after the FPC body is folded back, it is bonded and connected to the module iron frame by using the second conductive adhesive layer to form an electrical connection structure, and the module iron frame and the stainless steel reinforcement also form an electrical connection structure through the conductive adhesive. At this time, once static electricity is generated on the CND ITO layer of the InCell glass body, these static electricity will quickly flow away through the conductive channels constructed by the first conductive adhesive layer and the second conductive adhesive layer. Since the ground of the FPC body is separated from the ground of the InCell glass body, the FPC body is protected from electrostatic interference, thereby effectively improving the display effect.
