Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0014] see figure 1 Shown is a combined cross-sectional view of the first embodiment of the active solid-state light-emitting display of the present invention. The solid state light emitting display 10 includes a substrate 12 , a plurality of solid state light sources (Solid State Lighting) 14 and a plurality of thin film transistors (Thin Film Transistor) 16 . A buffer layer 122 is disposed on the surface of the substrate 12, and the buffer layer 122 is an insulation buffer layer (Insulation Buffer Layer). The material of the buffer layer 122 is selected from low temperature aluminum indium gallium nitride (Low Temperature AlInGaN, LT-AlGaInN), silicon oxide (SiOx), silicon nitride (SiNx), silicon oxynitride (SiON), hafnium oxide (HfOx), At least one of aluminum oxide (AlOx), tantalum oxide (TaOx) or barium strontium titanate (BaSrTiOx) or a combination thereof. ...

Description
technical field [0001] The invention relates to an active solid-state light-emitting display, in particular to an active solid-state light-emitting display in which an organic light-emitting source is replaced by a solid-state light-emitting source structure. Background technique [0002] The main technology of the new-generation Flat-Panel Display is an Active Matrix Organic Light Emitting Display (AMOLED) made of organic materials. Although the active organic light-emitting diode display has the advantages of high brightness, fast screen response, thin and short, full color, no viewing angle difference, no need for backlight, and power saving. However, the organic light-emitting material is easily affected by the process environment during the process, for example, moisture in the environment will cause degradation of the organic material. Therefore, the active OLED display needs to be fabricated in a vacuum environment, and a sealing process is required to avoid deterior...
