Problems solved by technology
The metal wiring in the peripheral area can be formed at the same layer as the electrode layer (anode or cathode) in the pixel area and at the same time, because the metal wiring in the peripheral area has a relatively wide width or a relatively large area, making its surface topography (topography) different from that of the pixel. The surface type of the electrode layer in the region is very different. For example, the surface roughness of the metal circuit in the peripheral region is not enough, which will affect the quality of the subsequent material layer. For example, the thickness of the insulating layer formed on the metal circuit in the peripheral region is too thin. , resulting in a short circuit between the two layers of metal lines above and below the insulating layer, which seriously affects the operation of the display panel
Furthermore, due to the relatively large area of the metal lines in the peripheral area, it is easy to generate excessive stress

Embodiments of the present invention provide a display panel and an image display system using the display panel. The display panel includes: a base, including a pixel area and a peripheral area; a control element, located on the base of the pixel area; a conductive layer, located on the On the base of the peripheral region; a first insulating layer located on the conductive layer of the peripheral region, wherein the area ratio of the first insulating layer to the conductive layer of the peripheral region is between about 0.27 to 0.99; a lower electrode layer on the first insulating layer; and a second insulating layer on the lower electrode layer.
Description
[0001] This application is a divisional application of the patent application with the filing date of April 23, 2009, the application number of 200910135642.1, and the invention title of "Display Panel and Image Display System Using the Display Panel". technical field [0002] The present invention relates to a display panel, and in particular to an active organic light emitting diode panel and an image display system using the display panel. Background technique [0003] Active light-emitting devices, such as light-emitting diodes and organic light-emitting diodes, have been widely used in flat panel displays. Among them, the active matrix organic electroluminescent diode (AM-OLED) has thin volume, light weight, high luminous efficiency of self-luminescence, low power consumption, wide viewing angle, high contrast, high response speed, and full color, etc. characteristics are valued. [0004] Generally, in an AMOLED panel, a wide (for example greater than 100 μm) and long ...
