Abstract

The invention relates to an OLED display device integrated with a solar cell and a manufacturing method thereof, and an OLED watch. The OLED display device integrated with a solar cell comprises an OLED area and a solar cell area. In the manufacturing method of the OLED display device integrated with a solar cell, a TFT first conductivity type semiconductor in the OLED area and a solar cell first conductivity type semiconductor in the solar cell area are formed by performing a photolithography and etching process on a first conductivity type semiconductor material layer, and an OLED cathode in the OLED area and a solar cell second polarity electrode in the solar cell area are formed by performing a photolithography and etching process on a metal layer. Thus, the number of times that the photolithography and etching process is performed is reduced by one and the number of masks needed is reduced by one in each step, and the process time and cost are saved.

Description

technical field [0001] The present invention relates to a semiconductor device, in particular to an OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display device integrating solar cells, a manufacturing method of the OLED display device integrating solar cells, and an OLED watch. Background technique [0002] Smart watches are gradually entering people's lives. Smart watches with low price and long standby time are very attractive to consumers. [0003] However, one of the shortcomings of some smart watches on the market is that the battery capacity is small, the power consumption is large, and the standby time is short. A traditional smart watch uses an organic light-emitting diode (OLED) display device as a display panel, and integrates a solar cell on the watch for power supply, so as to improve the escort capability of the smart watch. However, if the traditional manufacturing process is used, solar cells and OLEDs need to be produced separately, and ...
