摘要： The present disclosure provides an optical sensor, a manufacturing method thereof, a display device, and a display apparatus, and relates to the display technology. The optical sensor includes a thin film transistor and a PIN diode on a surface of a drain of the thin film transistor. A material of a P region of the PIN diode, a material of an I region of the PIN diode, and a material of an N region of the PIN diode are oxides. Since the PIN diode is made of oxides rather than amorphous silicon, hydrogen is not introduced. Therefore, the performance of the thin film transistor will not be affected, thereby achieving the improvement of the performance of the display device and the display effect.

摘要： The present invention provides a digital low dropout regulator and a control method thereof. The regulator comprises a voltage comparator, a counter, a decoder, a PMOSFET array and a divider. The voltage comparator receives an actual voltage output from the PMOSFET array through the positive input terminal, receives a reference voltage through the negative input terminal, and compares the actual voltage and the reference voltage to obtain a level signal. The divider calculates based on an output voltage pre-configured for a PMOSFET array and an actual voltage output by the PMOSFET array in at least two clock cycles to obtain a first value. The counter generates a control signal based on the level signal and the first value. The decoder receives the control signal transmitted by the counter and controlling the number of switched-on transistors, in the PMOSFET on a basis of the control signal.
