摘要： The present application relates to a display device that is divided into a first region as a fingerprint recognition region and a second region as a display region with the first region having a first light transmittance greater than a second light transmittance of the second region. The light transmittance of the region corresponding to the fingerprint recognition module group in the display device of the present application can be increased, thereby further improving the sensitivity of the fingerprint recognition module group.

摘要： A drive control circuit, a driving method thereof and a display device are provided. The drive control circuit includes a drive integrated circuit, a transmit control circuit, a scan drive circuit, and a pixel circuit. The drive integrated circuit adjusts a duty cycle of a drive signal to generate a first drive signal and transmits the first drive signal to the transmit control circuit. The drive integrated circuit decreases the amplitude of a data signal to generate a first data signal and transmits the first data signal to the scan drive circuit. The transmit control circuit converts the received first drive signal into a second drive signal with a preset duty cycle and transmits the second drive signal to the pixel circuit. The preset duty cycle of the second drive signal is greater than the duty cycle of the drive signal to be outputted.

摘要： An active matrix organic light-emitting diode (AMOLED) display device and a controlling method thereof. The AMOLED display device (100) comprises a system power IC (110), a driver IC (120), an AMOLED panel (130), a power line (111) and a feedback line (112). The AMOLED panel (130) includes a plurality of pixel circuits. The system power IC (110) outputs a positive power supply voltage (ELVdd1) to the plurality of pixel circuits via the power line (111), and the driver IC (120) detects a positive power supply voltage (ELVdd2) actually applied to the plurality of pixel circuits via the feedback line (112) and compensates for data voltages (Vdata) based on the positive power supply voltage (ELVdd2) actually applied to plurality of pixel circuits. The driving chip detects the positive power supply voltage (ELVdd2) actually applied to plurality of pixel circuits, and automatically adjusts a minimum grayscale voltage (VREG1) and a maximum grayscale voltage (VGS) based on the positive power supply voltage (ELVdd2) actually applied to the plurality of pixel circuits, such that a certain difference value can be maintained between the data voltage (Vdata) and the positive power supply voltage (ELVdd2) actually applied to the plurality of pixel circuits, thus eliminating Gamma offset.
