Problems solved by technology

If the glue is sintered at high temperature, such as laser sintering the glass glue of the OLED panel (the well-sealed glass glue can make the water resistance of the OLED product packaging reach 10 -6 g / m 2 / day, glass glue is generally sintered by laser), because the path of the laser beam that melts the glue will cross the metal wiring and the metal block, the heat generated by the laser beam will be affected by the difference between the metal material and the metal pattern (metal High reflectivity and good thermal conductivity, etc.), so there is no metal area and the interface area is easy to cause differences in heat conduction (thermal expansion and cold contraction) due to the difference in the properties of the two (metal and non-metal), making the adhesive After sintering, materials and glass may have cracks, and there is a risk of poor adhesion between substrates
Poor encapsulation of the display panel will result in lower yield and lower reliability of the panel

[0046] figure 1 A partial schematic diagram of a display panel according to the first embodiment of the present invention is shown. A display panel includes a first substrate, a second substrate corresponding to the first substrate, and a sealant located between the first substrate and the second substrate and adjacent to the edges of the two substrates for bonding the first substrate and the second substrate. substrate. When the display panel in the embodiment is, for example, an organic electroluminescent display panel (OLED), it further includes an organic light emitting layer located between the first substrate and the second substrate. The first substrate and the second substrate are, for example, a color filter substrate (CF substrate) and a thin film transistor substrate (TFT substrate) respectively. The following uses a thin film transistor substrate as the second substrate to propose a related structure for description of an embodiment. However, the structures of th...

Abstract

The present invention proposes an organic electroluminescent display panel, which includes a first substrate, a second substrate corresponding to the first substrate, an organic light-emitting layer between the first and second substrates, and a sealant between the first and second substrates. Between the two substrates and adjacent to the edge of the two substrates, a pattern change area and an auxiliary pattern area. The second substrate has a frame glue coating area, a metal area and a non-metal area adjacent to the metal area, and the metal area includes a plurality of wires. The frame glue is located at the frame glue coating area of ​​the second substrate. The pattern change area is located at one of the plurality of wires in the metal area and corresponds to the sealant coating area. The pattern change area has a plurality of conductive parts. The auxiliary pattern area is located at the non-metal area and has a plurality of auxiliary conductive parts. Wherein, the width of the conductive portion in the metal region is larger than the width of the auxiliary conductive portion in the non-metal region.

Description

technical field [0001] The present invention relates to a display panel, and in particular to a display panel with a conductive pattern change area. Background technique [0002] Electronic products with display panels have become an indispensable necessity for modern people, whether in work, study, or personal leisure and entertainment, including smart phones (SmartPhone), tablet computers (Pad), notebook computers (Notebook), monitors (Monitor) to TV (TV) and many other related products. For the display panel, the pollution and erosion of water vapor will affect the operating life of the display panel. Among them, the organic electroluminescent display panel (OLED) is most sensitive to the presence of moisture and oxygen. [0003] Since the organic material and highly active cathode metal in the organic electroluminescent display panel are extremely sensitive to moisture and oxygen, once the packaging process is flawed and the moisture and oxygen penetrate, the entire de...
