Description

1273861 A7 B7 V. OBJECT DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a panel device, and more particularly to a panel device using an organic material as a light-emitting unit. [Background of the Invention] An organic electroluminescent display (OLED) is one of the most promising flat display devices. The luminescence single τ used in the organic electroluminescent display (OLED) is quite different from the liquid crystal display technology in which the liquid crystal is used as the optical switching medium. The illuminating unit of the OLED is self-illuminating when the current is conducting, and the LCD or TFT_LCD The panel still requires an additional backlight module as the source of light. Therefore, how to utilize the characteristics of the organic electroluminescent material itself to improve the space utilization elasticity of the OLED panel and to have an aesthetic layout has become an important issue for the industry to solve. In the past, the passive 〇LED panel layout was mostly arranged on the adjacent sides of the panel. In the panel layout of a generally passive small-sized OLED device, a transparent conductive layer (for example, indium tin oxide (IT0)) is used as a lead. With bismuth tin oxide as the lead, its conductivity is not as good as that of metal materials, which has a high impedance problem; especially in OLED, the self-luminous organic functional material layer is more conductive than the cathode metal layer or anode. There are a lot of differences, which leads to the traditional way of laying LCD or TFT-LCD panel layout. When 〇lED is '0 LED flow, the degree of burning cannot be increased south', so the display quality such as brightness, contrast and viewing angle are not in accordance with the product requirements. Power consumption is large. 4 This paper scale applies to China National Standard (CNS) A4 specification (210X297 public) ~ -- (Please read the notes on the back and fill in the columns on this page) Pack-------- - 1273861 A7 ______B7____ V. INSTRUCTIONS (I) In addition, the configuration of the leads of the conventional OLED display panel is mostly a Χ-γ lead configuration. With such a layout configuration, since the leads are located only on one side of the panel, an asymmetrical configuration is formed, resulting in a waste of unsightlyness or space configuration, and the arrangement is concentrated on one side, which is inconvenient in assembly. When the display area needs to be improved in resolution, the width of the guide line area (XY lead area) often needs to be widened in the case where the number of electrodes or the guide line cannot be reduced, which causes the display device to occupy a large space in application. Disadvantages. Therefore, how to implement the electromechanical excitation panel and how to control the integrated circuit (IC) during packaging is how to reduce the mass production cost, improve the space utilization rate, and increase the performance of the display component, which is also a problem to be solved. The inventor of the present invention, in the spirit of active invention, thought of an "organic electroluminescent panel device" that could solve the above problems, and after several research experiments, completed the invention of the Jiahui people. SUMMARY OF THE INVENTION The main object of the present invention is to provide a system integration device for an organic electroluminescent panel that improves the space utilization flexibility of the display device and integrates all components in the device to increase the performance of the display device. Another object of the present invention is to provide an organic electroluminescent panel device which can improve the spatial symmetry of the panel and facilitate panel assembly, thereby improving the yield, reliability and process reworkability of the panel assembly. In order to achieve the above object, the organic electroluminescent panel device of the present invention is coupled to at least one external cable. The organic electroluminescent panel device mainly comprises at least one integrated circuit crystal having a plurality of pins.
