Organic electroluminescence display device
View Patent ↗The strength of the whole OLED is increased by proposing a new method of fixing OLED panels. To address the problem, an OLED element is formed on a substrate, and a sealing substrate of a structure by which the substrate is sealed is fixed to a lower metallic frame via an elastic sheet. Silicon resin is preferably used as the sheet, and use of a sheet having a heat diffusion function based on radiation is more desirable.
1. An organic EL display device, comprising:
an OLED panel, wherein an OLED element is formed on a substrate, and a sealing substrate of a structure by which the substrate is sealed,
a lower metallic frame having a flat inner surface and walls,
the sealing substrate is fixed to the flat inner surface of the lower metallic frame via an elastic sheet of silicon resin,
the elastic sheet is not existing between the sealing substrate and the wall of the lower metallic frame, and
wherein the gap between the sealing substrate and the wall of the lower metallic frame is bigger than a half of the thickness of the OLED panel.
2. The organic EL display device of claim 1 ,
wherein the elastic sheet is dispersed with carbon black fillers, or infrared absorption ceramic, or Ni powder.
