[Previous Technology] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is a type of flat panel display. The panel can be regarded as a liquid crystal sandwiched between two glass substrates, and the upper glass substrate is A color filter is combined, and a lower layer of glass has a transistor mounted thereon. When a current is passed through the transistor to generate an electric field change, causing the liquid crystal molecules to deflect, thereby changing the polarity of the light, and then using a polarizer to determine the light and dark state of the Pixel. In addition, the upper glass is bonded to the color filter and the light sheet, and each of the pixels (Pixel) contains three colors of red, blue and green. These red, blue and green colors form the image on the panel. A schematic diagram of a liquid crystal display shown in Figs. 1A and 1B, wherein Fig. 1A shows the state before the electric field is applied, and Fig. iB shows the application of the electric field. Taking the most common general nematic liquid crystal as an example, an electric field 102 is applied between the upper glass substrate 104 and the lower glass substrate 1〇6, causing the liquid crystal molecules to turn toward 'because the optical axis of the liquid crystal is substantially identical to its molecular axis. , thereby producing an optical effect' and if we properly arrange the arrangement side of the liquid crystal at the beginning of the liquid crystal 1287681:, when the electric field 1〇2 applied to the liquid crystal molecules is removed, the liquid crystal knife 100 will be elastic due to its own And the viscosity, and very quickly restore the state before the electric field 102 was added. The production of thin film transistor liquid crystal displays can be mainly divided into: Array process, (2) panel process, and (7) module (fine e) process. Among them, array fabrication mainly involves forming a plurality of transistors on a glass substrate through a semiconductor-like manufacturing technique (coating, exposure, development, etching, etc.). The panel manufacturing mainly consists of aligning the substrate processed by the array process with the glass substrate bonded to the color filter, and aligning it by the alignment of the inspection machine, and then firing the frame rubber to cut into a predetermined size panel. The liquid crystal is injected, and the polarizing plate is attached and tested. Finally, the panel module is made, mainly to set up the cut panel and external components such as the drive 1C, circuit board, and backlight board. 2 is a view showing a liquid crystal panel and a thin film transistor panel assembled with a κ section 'optical liquid crystal panel 2 2 2 attached with a color light-passing sheet 2 2 and a thin film transistor panel 204 having a transparent display electrode 208 The liquid crystal molecular layer 206 is filled in the middle and sealed with a sealant 216 to prevent liquid crystal molecules from flowing out. On the inner surfaces of the liquid crystal panel 202 and the thin film transistor panel 204, an alignment layer 218 is applied to align the liquid crystal molecular layer 206, and the outer surface is attached with a polarizing plate 214, respectively. A short-circuit transmission conductor 220 is connected to one of the conductive pads 222 on the thin film transistor panel 204, and the other end is connected to the common electrode 2 1 0 on the liquid crystal panel 202. The main purpose is to make the liquid crystal panel 202 and the thin film electrically The crystal panel 204 has a common electrode potential of 1287681. Fig. 3 shows a case where the sealant 21 is applied to the periphery of the thin film transistor panel 204 when the liquid crystal panel 202 and the thin film transistor panel 204 are bonded together. Wherein the thin film transistor panel 204 is a thin film transistor array region 228, and the periphery is a placement region of the gate side integrated circuit 224 and the source side integrated circuit 226, respectively, in the thin film transistor array region 228 and the integrated body. In the circuit 2 2 4, 2 2 6 is the wire arrangement area 2 3 0. There are four further conductive pads 222 on the four sides of the panel for placing short-circuited transfer conductors 220 (not shown). Referring to Figures 4 and 5, an enlarged view of the region 23 2 is a conventional coating of the mask 2 216 in the vicinity of the conductive pad 222. In the coating structure shown in Fig. 4, when the sealant 2 16 is applied, a part of the conductive pad 222 is covered, which results in poor electrical signal transmission and poor display. Conventionally, the coating structure shown in FIG. 5 is modified to avoid the conductive pad 222 in a right-angled manner. However, there is a risk of two degradation cracks in the stress concentration of the sealant at the right angle, and In the case of a right angle, an excessive amount of the sealant 216 is often accumulated at a right angle 234 during coating, causing stress concentration of the sealant 216 to deteriorate and break, resulting in leakage and contamination of the liquid crystal. SUMMARY OF THE INVENTION In view of the above-mentioned background of the invention, the conventional framed coating structure often has a conductive germanium partially covered to cause poor electrical signal transmission, resulting in liquid 1287681.

Traditionally, in order to avoid the conductive pad partially covering the conductive pad, it will cause a frame at a right angle (and the accumulation of the amount of the frame glue, or even a pad of a liquid crystal display, while avoiding the frame glue, therefore, the main purpose of the present invention is The invention provides a frame glue structure, which utilizes a multi-segment curved structure to avoid the conductive pad, and has a large amount of accumulation. The object is to provide a frame cementing of the liquid crystal display. Another structure of the invention can be avoided because the structure of the right angle is not used. The frame glue stress concentration is concentrated and deteriorates and fractures. The liquid crystal display frame glue coating structure of the invention is close to the conductive pad adjacent area, and the multi-stage bending method is used to avoid the conductive pad by means of a straight angle, so as to avoid the frame glue covering the conductive pad; The linear sealant is located at the periphery of the substrate and has at least one fracture region adjacent to the vicinity of the conductive pad, so the linear sealant is not in contact with the conductive pad, and at least one arc structure is used to join and form The invention relates to a multi-section bending frame structure. [Embodiment] Without limiting the spirit and application scope of the present invention In the following, the embodiment of the present invention will be described by way of an embodiment; those skilled in the art, after understanding the spirit of the present invention, can apply the frame seal structure of the present invention to various liquid crystal displays which are not related to 1287681. The invention does not have a multi-section bending/adhesive structure of a right-angled structure to avoid the conductive pad, and avoids the conduction resistance rising due to the partial conduction pad being covered by the frame rubber, so that the common electrodes of the upper and lower glass substrates are present due to electrical differences. The invention has different potentials. On the other hand, since the structure of the present invention does not have a right-angle structure, it is also possible to avoid the phenomenon that the frame glue is deteriorated and broken due to stress concentration, causing liquid crystal contamination and leakage, and the following is only one of the inventions. The preferred embodiment is not intended to limit the scope of application of the present invention. Referring again to FIG. 3, a schematic view of a conventional thin film transistor panel 204 is shown in the middle of the thin film transistor panel 2〇4. The crystal array region 228 is surrounded by a placement region of the gate side integrated circuit 224 and the source side integrated circuit 226, respectively, in the thin film transistor array region 22 8 and the integrated circuits 224, 226 are the wire arrangement areas. There are four conductive pads 222 on the four sides of the panel for placing the short-circuit transmission conductors 22. The invention is mainly changed to the vicinity of each of the conductive pads 222. The inner frame glue coating structure prevents the frame rubber from covering the conductive pad, and causes the difference of the common electrode potentials of the upper and lower substrates, which affects the quality of the displayed surface. The figure 6 shows the frame glue in the vicinity of the conductive crucible of the present invention. An enlarged schematic view of the coating structure, the area shown in this figure is the 232 area of FIG. 3. The frame seal structure 234 of the present invention avoids the conductive pad 222 by means of a plurality of sections, wherein the frame seal structure of the present invention The two portions of the 234 adjacent to the conductive pad 222 are shielded from the conductive pad by an arc-shaped frame structure that is bent inwardly, and the two-way inner curved arc-shaped frame seal structure will be 1287681

As shown in Fig. 6, when using the frame glue gun to carry out ώ w ± ^ from right to left, when the conductive pad 222 is encountered, the frame glue can be preliminarily coated with 9〇2 n arcs and then clockwise rounded at 9G degrees. The arc is forward-coated with IT, coated with a 9G counterclockwise arc, and finally moved from top to bottom to avoid the conductive pad 222. In other words, when the frame glue is applied in the present invention, a linear frame seal is formed on the periphery of the substrate, and when the conductive pad 22 is encountered, a curved frame seal is formed to bypass the conductive pad. According to the above description, the frame-coating structure of the liquid crystal display of the present invention avoids the conductive 塾 by avoiding the conductive 塾 by using a plurality of sections of the adjacent area of the conductive pad to avoid the frame adhesive covering the conductive pad. For example, the present invention forms a multi-segmented frame of the present invention by circumventing a conductive pad at the adjacent conductive pad by an arc-shaped frame structure that is bent inwardly while using another arc structure.
