Problems solved by technology
[0014] At this time, even if the speed or nozzle of the coating machine is changed, the coating liquid will spread due to the low viscosity and easily exceed the slit line of the TCP. Therefore, considering the limit of the process, the length of the TCP can only be increased
If the desiccant is applied beyond the dividing line and becomes hard, the TCP cannot be bent on the dividing line, so there is a problem
[0015] Therefore, in the plasma display device of the prior art, there are additional coating processes at the front and rear of the TCP, the operation is cumbersome, and the length design of the TCP also exceeds the required length, so the manufacturing cost will also increase.
[0016] In addition, there is another problem that, as shown in Fig. 4, when using the jig for applying the desiccant in the prior art, the TCP tape hangs downward, making it difficult to apply the desiccant on the back side.

The invention discloses a plasma display equipment of flexible circuit board with desiccant osmotic through-hole, which comprises the following parts: upper and lower panels of electrode, data driving board on the back of panel, flexible circuit board with IC chip driving device to connect the panel and data driving board, wherein the flexible circuit board forms desiccant osmotic through-hole on the TCP surface to interconnect the front and back of board. The invention keeps certain distance between TCP and panel during desiccant coating stage, which improves the coating effect.
Description
technical field [0001] The present invention relates to a plasma display device, in particular to a plasma display device with a flexible circuit board formed with a desiccant penetration hole for improving the TCP desiccant coating process and a manufacturing device thereof. Background technique [0002] As we all know, a plasma display (PDP; Plasma Display Panel) is a representative of a large display, which has excellent characteristics such as self-illumination, high-speed response, and wide viewing angle. Recently, in order to reduce the cost of PDP and improve the work flow, the data-driven IC packaging form tends to be changed from COF (Chip on Film) to TCP (Tape Carrier Package thin film packaging). In this way, if a flexible circuit board such as COF or TCP is used, the cost of packaging can be reduced, and the automation of the packaging supply and sticking process can be realized. [0003] FIG. 1 is a side sectional view of a prior art plasma display device inclu...
