The invention discloses a double-sided display device and a driving method thereof, and relates to the field of display technology; the driving method of the display stage includes: in the first display state, the gate line transmits a driving voltage to turn on the first transistor, and the data line and the first The absolute value of the voltage difference input at the power supply voltage terminal is greater than the threshold voltage of the electrophoretic light-emitting structure, and the absolute value of the difference between the voltages input at the second power supply voltage terminal and the first power supply voltage terminal is less than the threshold voltage of the light-emitting element; in the second display state In this case, the difference from the first display state is that the absolute value of the difference between the voltage input from the second power supply voltage terminal and the first power supply voltage terminal is greater than the threshold voltage of the light-emitting element; in the third display state, the same as the first display state The difference is that the absolute value of the voltage difference between the data line and the first power supply voltage terminal is smaller than the threshold voltage of the electrophoretic light-emitting structure, and the absolute value of the voltage difference between the second power supply voltage terminal and the first power supply voltage terminal is greater than the light emitting structure. element threshold voltage.
Description
technical field [0001] The present invention relates to the field of display technology, and more particularly, to a double-sided display device and a driving method thereof. Background technique [0002] In the prior art, conventional Mini-LEDs or Micro-LEDs are processed on the array layer by mass transfer to achieve independent display after the array layer is fabricated, but LED lights are processed after the array layer is completed. It is very difficult to transfer a large amount of large amount, and the good yield rate is low. Or, in the prior art, LEDs are used as the backlight, and a planarization layer is covered on the upper layer of the LEDs, and the rest of the film layers are sequentially fabricated on the side of the planarization layer away from the LEDs, wherein the LEDs used as the backlight are in a constant light state , high power consumption and low contrast. In addition, the display devices provided in the prior art can generally only realize single-...
