A display device and a display method are provided. The display device includes a display screen, and wherein the display screen includes a first displaying area and a second displaying area. The first displaying area is in a non-displaying state when a main control system receives a specific signal for driving a recognizing module, and the first displaying area is in a displaying state when the main control system does not receive the specific signal for driving the recognizing module.

Display device and display method background of the disclosure

The present disclosure relates to a full screen module and a smartphone. The full screen module includes a display panel, a driving chip electrically connected to the display panel, a first flexible circuit board electrically connected to the driving chip, a photoreceptor panel configured on the display panel, and a second flexible circuit board electrically connected to the photoreceptor panel and the first flexible circuit board. The photoreceptor panel is configured to receive light signals, to transform the light signals into digital signals, and to transmit the digital signals to the driving chip. The driving chip is configured to transform the digital signals into data signals, and to drive the display panel to display images. The photoreceptor panel may replace the front camera module of the conventional smartphone. As such, the screen ration of the smartphone may be improved.

Full screen module and smartphone

A pixel driving circuit includes a signal loading component, a storage capacitor, a compensation component, a mirror component, and a drive transistor. In a data transmission stage, the signal loading component transmits a received image data signal to the gate of a drive transistor, which is stored in a storage capacitor; and in a threshold voltage compensation stage, the compensation component connects the gate of the drive transistor to the source of the drive transistor so as to generate a drive signal dependent upon the threshold voltage of the drive transistor from the signal stored in the storage capacitor and to drive an organic light emitting diode to emit light, thus eliminating an influence of the threshold voltage of the drive transistor on the current through the organic light emitting diode and preventing the brightness of the organic light emitting diode from varying over its operating period of time.
