Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal display technology, and specifically to a liquid crystal cell for rapid electrostatic discharge. Background Technology
[0002] LCD technology achieves its display function by applying voltage to liquid crystals through electrodes to control the alignment of the liquid crystals. In areas without display or traces, excess electrodes need to be etched away, while in areas with display and traces, the electrodes are retained. Due to the difference in refractive index between areas with and without electrodes, trace display issues can occur. To improve these trace display problems, electrode filler blocks are added to the corresponding non-layer locations in the trace area for compensation. However, these filler blocks are individual electrodes without grounding. When exposed to external static electricity, static charge easily accumulates and cannot dissipate, creating a potential difference with the corresponding electrode below, forming an electric field. This causes the filler block to be visible and persist for extended periods, severely impacting the user experience. In cases of excessively strong static electricity that cannot dissipate promptly, it can even damage the monitor, affecting its lifespan. Utility Model Content

[0034] The upper conductive layer 2 is a COM conductive layer, and the lower conductive layer 6 is a SEG conductive layer. The upper electrode layer 2 and the lower electrode layer 6 are disposed opposite to each other, and the liquid crystal layer 4 is disposed between the upper electrode layer 2 and the lower electrode layer 6. The frame adhesive 7 is located between the upper electrode layer 2 and the lower electrode layer 6 and surrounds the liquid crystal layer 4, so that the liquid crystal layer 4 fills the sealed space surrounded by the upper electrode layer 2, the lower electrode layer 6, and the frame adhesive 7.
[0035] The alignment layer 3 includes an upper alignment layer 31 and a lower alignment layer 32, which are located on the upper and lower sides of the liquid crystal layer 4, respectively. Specifically, the upper alignment layer 31 is located between the upper electrode layer 2 and the liquid crystal layer 4, and the lower alignment layer 32 is located between the lower electrode layer 6 and the liquid crystal layer 4. The alignment layer 3 is used to guide the liquid crystal molecules to align in an orderly manner in a specific direction, thereby controlling the transmission or blocking of light and realizing the display function.
[0036] Substrate 1 includes an upper substrate layer 11 and a lower substrate layer 12. An upper electrode layer 2 is located between the upper substrate layer 11 and the upper alignment layer 31, while a lower electrode layer 6 is located between the lower substrate layer 12 and the lower alignment layer 32.

Substrate 1 is made of glass and serves as a basic support layer, acting as a carrier for other functional layers and providing mechanical stability, thermal stability, and interface compatibility.
[0037] like Figure 2 As shown, the lower electrode layer 6 is positioned directly below the upper electrode layer 2; the upper electrode layer 2 includes several COM trace electrodes 21 and several first fill electrodes 22; the lower electrode layer 6 includes several SEG trace electrodes 61 and several second fill electrodes 62; the first fill electrodes 22 are configured in a one-to-one correspondence with the SEG trace electrodes 61, and the second fill electrodes 62 are configured in a one-to-one correspondence with the COM trace electrodes 21. That is, the SEG trace electrode 61 is located directly below its corresponding first fill electrode 22, and the second fill electrode 62 is located directly below its corresponding COM trace electrode 21 (in... Figure 2 The upper electrode layer 2 and the lower electrode layer 6 overlap vertically, the SEG trace electrode 61 and the first fill electrode 22 overlap vertically, and the second fill electrode 62 and the COM trace electrode 21 overlap vertically. The upper electrode layer 2 is provided with the first fill electrode 22, and the lower electrode layer 6 is provided with the second fill electrode 62, which can solve the trace display problem.
[0038] The first filling electrodes 22 of the upper electrode layer 2 are electrically connected to each other. Specifically, a COM layer interconnect electrode 23 is provided between two adjacent first filling electrodes 22, and the COM layer interconnect electrode connects the two adjacent first filling electrodes 22. The second filling electrodes 62 of the lower electrode layer 6 are electrically connected to each other.

The ground electrode 9 can also be directly electrically connected to its nearest second filling electrode 62.
[0039] The first filling electrodes 22 are electrically connected to each other and electrically connected to the ground electrode 9 through the conductive element 5. The second filling electrodes 62 are electrically connected to each other and electrically connected to the ground electrode 9. This allows static electricity accumulated on the first and second filling electrodes to be discharged through the ground electrode 9, preventing static electricity buildup from affecting the display effect and lifespan of the LCD. Connecting adjacent first filling electrodes 22 through COM layer interconnection electrode 23 and adjacent second filling electrodes 62 through SEG layer interconnection electrode 63, with the ground electrode 9 electrically connected to the nearest first filling electrode 22 and second filling electrode 62, simplifies the wiring and allows for a minimal wiring layout to electrically connect all first filling electrodes 22 and second filling electrodes 62 to the ground electrode 9.
[0040] Furthermore, the frame adhesive 7 has holes inside or receiving openings on its edges, through which the conductive element 5 connects to the first filling electrode 22 and the grounding electrode 9. The conductive element 5 is disposed within the holes or receiving openings, which helps save wiring space and protects the conductive element 5. Preferably, the conductive element 5 is a conductive adhesive containing conductive gold balls, with the conductive gold balls accounting for 2.5% to 4.5% of the conductive adhesive's mass.
[0041] In this embodiment, the upper electrode layer 2 is further provided with a COM layer fill-out electrode 10 electrically connected to the first fill electrode 22, and the COM layer fill-out electrode 10 is electrically connected to the conductive component 5.

The COM layer fill-out electrode 10 is provided on the upper electrode layer 2 to facilitate the alignment and connection of the conductive element 5 with the COM layer fill-out electrode 10 during assembly.
[0042] Several second filling electrodes 62 are electrically connected to the grounding electrode 9. It should be noted that in some other embodiments, the grounding electrode can also be located on the upper electrode layer, and the several second filling electrodes are connected to the grounding electrode via conductive elements. In some other embodiments, grounding electrodes can also be provided on both the upper and lower electrode layers, with the first filling electrode electrically connected to the grounding electrode of the upper electrode layer and the second filling electrode electrically connected to the grounding electrode of the lower electrode layer. This achieves a grounding design for both the first and second filling electrodes, enabling rapid static electricity discharge. Moreover, according to this implementation scheme, no conductive elements are required.
[0043] Furthermore, the lower electrode layer 6 is also provided with stepped PIN electrodes, including a COM layer PIN electrode 65 and a SEG layer PIN electrode 64. The COM trace electrode 21 is electrically connected to the COM layer PIN electrode 65. Specifically, the COM trace electrode 21 and the COM layer PIN electrode 65 are electrically connected through conductive adhesive, and the interior or edge of the frame adhesive has holes or openings to accommodate the conductive adhesive. The SEG trace electrode 61 is electrically connected to the SEG layer PIN electrode 64.
[0044] In some other embodiments, the stepped PIN electrode can also be disposed on the upper electrode layer, and the SEG trace electrode 61 and the SEG layer PIN electrode 64 are electrically connected by conductive adhesive.
