Abstract

The invention provides a display device and a control method thereof. The display device comprises an organic light emitting structure layer, a control assembly and a control module. The control assembly comprises a color resist layer and a control electrode layer, wherein the color resist layer and the control electrode layer are stacked. The color resist layer is close to the organic light emitting structure layer relative to the control electrode layer. The control module is coupled to the control electrode layer. The color resist layer comprises a color resist region and a light transmitting region, wherein the color resist region and the light transmitting region are spaced apart. The control electrode layer at least comprises a first electrode which is arranged on the color resist region. The first electrode is capable of changing the transmittance under voltage. The control module is coupled to the first electrode, and is used for outputting voltage to the first electrode to control the transmittance of the first electrode. The display device can reduce the transmittance of the first electrode by controlling the magnitude of the applied voltage of the first electrode, so that the first electrode obscures the color resist layer. A display image is obscured. The display device has an image peeking prevention function, which ensures the information security of the display image.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a control method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) has the advantages of self-illumination, wide viewing angle, high contrast ratio, low power consumption, and high response speed, and is widely used in the field of display technology. [0003] The display device made based on organic light-emitting diodes mainly includes an organic light-emitting structure layer. The organic light-emitting structure layer includes a laminated substrate, anode, organic light-emitting layer and cathode. When the display device is in operation, the anode and the cathode of the organic light-emitting layer are respectively A voltage is applied to the cathode to cause electron migration and hole transition to occur in the organic light-emitting layer, thereby realizing the light emission of the organic light-emitting layer and fin...
