Embodiment Construction
[0039] In order for those skilled in the art to better understand the technical solutions of the present invention, the low-temperature polysilicon backplane, its manufacturing method, and light-emitting devices provided by the present invention will be described in detail below with reference to the accompanying drawings.
[0040] figure 1 A schematic structural diagram of an LTPS backplane provided in Embodiment 1 of the present invention, as shown in figure 1 As shown, the LTPS backplane includes: a base substrate 11 , a thin film transistor 12 and a light blocking layer 13 located above the base substrate 11 , and the light blocking layer 13 is located above the thin film transistor 12 . The light blocking layer 13 is used to block the irradiation light from being irradiated to the thin film transistor 12 .
[0041] In this embodiment, the irradiation light is ultraviolet light, which may be ultraviolet light used in the exposure process or ultraviolet light in the enviro...
