Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display screen production, in particular to an LCD large-plate structure capable of improving liquid crystal puncture. Background Art
[0002] One of the commonly used materials for mobile phone displays is liquid crystal display, namely TFT-LCD (thin film transistor liquid crystal display). It is composed of an upper glass CF and a lower glass TFT with different functions bonded together into a box by frame glue. The box is filled with liquid crystal. The display forms an electric field through the circuit matrix on the TFT, and then controls the rotation angle of the liquid crystal through this electric field to control the amount of light passing through to form different display images.
[0003] Liquid crystal and frame glue are both polymer materials. After the TFT-LCD is formed, the liquid crystal molecules will penetrate into the interface between the frame glue and the glass to a certain extent. When the frame glue width is too narrow or the pressure inside the box is too high, it is more likely to cause the liquid crystal molecules to pass through the frame glue to the outside of the box, which is the phenomenon of liquid crystal puncture, and then the inside and outside of the liquid crystal box are connected, and the outside air impurities enter, causing the liquid crystal molecules to rotate uncontrollably and form a black mass of liquid leakage. Therefore, the following problems are prone to occur in the production process of LCD screens:
[0004] Since the size of TFT-LCD substrates (i.e. LCD large panels) varies according to the generation line, generally, LCD large panels are designed according to the size of specific small LCD panels to plan the LCD middle panel with reasonable utilization. Usually, LED large panels are cut by a cutter wheel, and a groove of a certain depth is pre-cut between the LED middle panels, and then bent and cracked by machine or manual methods. During the cracking process, the small LCD panels at the edge of the LCD middle panels will be squeezed to a certain extent, which will put a certain pressure on the liquid crystal in the box, prompting the liquid crystal to penetrate out of the frame glue faster, causing leakage and black mass defects, that is, causing the liquid crystal puncture problem.

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0024] See also Figure 1 , Figure 2 and Figure 3 As shown, an LCD large panel structure capable of improving liquid crystal puncture includes: an LCD large panel body 100 and a frame glue, wherein a plurality of LCD middle panels 110 are divided and formed on the LCD large panel body 100, and a plurality of small liquid crystal panels 111 are formed in each LCD middle panel 110, and a non-functional area is arranged between two adjacent LCD middle panels 110, and the frame glue includes a plurality of sealing frame glues 210 and a plurality of supporting frame glues 220, each sealing frame glue 210 is arranged around the periphery of each small liquid crystal panel 111, each supporting frame glue 220 is respectively arranged on the non-functional area, and each supporting frame glue 220 is respectively arranged around each LCD middle panel 110.
[0025] It should be noted that, in order to improve production efficiency, the LCD display screen is usually processed directly on the large plate, and then cut into single small pieces of liquid crystal panels 111 after completion. In this process, it is also necessary to first cut the LCD large plate into LCD middle plates through a cutter wheel, and a groove of a certain depth will be pre-cut between adjacent LCD middle plates 110, and then bend and split by machine or manual bending. In the process of splitting, the small piece of liquid crystal panel 111 near the edge of the cutting groove of the LCD middle plate 110 will be squeezed to a certain extent, and after squeezing, a certain pressure will be caused to the liquid crystal inside the small piece of liquid crystal panel 111, prompting the liquid crystal to penetrate outside the sealing frame glue, causing leakage black mass. Therefore, in the utility model, by filling and setting the support frame glue 220 in the area where the split groove needs to be cut, that is, filling the support frame glue 220 in the non-functional area, the support capacity is improved by the support frame glue 220, when splitting, the pressure of the bending action on the small piece of liquid crystal panel 111 near the edge of the LCD middle plate 110 can be reduced, avoiding the problem of liquid crystal 300 puncturing outward due to pressure. Specifically, the LCD panel body 100 includes an upper glass panel 100a and a lower glass panel 100b, and the frame glue is located between the upper glass panel 100a and the lower glass panel 100b, that is, the sealing frame glue 210 and the supporting frame glue 220 are both located between the upper glass panel and the lower glass panel, and the supporting frame glue is located in the area where the crack groove needs to be set, that is, the non-functional area. When cracking, the upper glass panel and the lower glass panel are supported by the supporting frame glue. When bending, the squeezing force generated by the upper glass panel and the lower glass panel approaching each other can be reduced, thereby reducing the squeezing force on the liquid crystal, thereby improving the liquid crystal puncture problem.
[0026] In this embodiment, the upper glass plate is CF (color filter) glass, and the lower glass plate is TFT (thin film field effect transistor) glass.
[0027] Preferably, there are six LCD middle panels 110. The six LCD middle panels 110 are distributed in a rectangular array.
[0028] Preferably, the thickness of the sealing sealant is equal to the thickness of the supporting sealant. In this way, it can be ensured that the upper glass plate and the lower glass plate are parallel to each other. In addition, the width of the supporting sealant needs to be matched with the width of the non-functional area. When the non-functional area is wide enough, the width of the supporting sealant is as large as possible to ensure the supporting strength.
[0029] Furthermore, each LCD middle plate 110 is in a rectangular structure. The outer shape structure of the LCD middle plate 110 can be matched and set according to the structure of the small liquid crystal panel 111, with the best layout utilization rate as the standard.
[0030] Furthermore, the small liquid crystal panels 111 are in a rectangular structure, and the multiple small liquid crystal panels 111 formed in the same LCD middle plate 110 are distributed in a rectangular array. The rectangular array distribution can make the layout utilization rate of the small liquid crystal panels higher.
[0031] Furthermore, each sealing glue 210 and each supporting glue 220 is a one-time molding structure. That is, when applying the sealing glue 210, a certain width of supporting glue 220 can be directly applied on the non-functional area to achieve one-time molding of the sealing glue 210 and the supporting glue 220 to improve production efficiency.
[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
