Display device, driving method thereof, and display system

A display system, comprising:

• a pair of peep-proof glasses and the, a display device, comprising:
• a display panel, a polarizer disposed on a light emitting surface of the display panel, and a phase retarder disposed on a light emitting surface of the polarizer, wherein a display region of the display panel comprises a peep-proof area and a compensation area;
• the phase retarder comprises:
• a first phase retarder corresponding to the peep-proof area and a second phase retarder corresponding to the compensation area;
• both the first phase retarder and the second phase retarder are a quarter-wave phase retarder;
• and
• the first phase retarder and the second phase retarder are configured to respectively convert light that is incident into the first phase retarder and light that is incident into the second phase retarder into polarized light with opposite rotation directions, in operation,
• wherein the pair of peep-proof glasses comprises a lens which is configured to transmit light outputted from the first phase retarder and block light outputted from the second phase retarder.

A driving method of a display device, comprising:

• a display panel, a polarizer disposed on a light emitting surface of the display panel, and a phase retarder disposed on a light emitting surface of the polarizer, wherein a display region of the display panel comprises a peep-proof area and a compensation area;
• the phase retarder comprises:
• a first phase retarder corresponding to the peep-proof area and a second phase retarder corresponding to the compensation area;
• both the first phase retarder and the second phase retarder are a quarter-wave phase retarder;
• and the first phase retarder and the second phase retarder are configured to respectively convert light that is incident into the first phase retarder and light that is incident into the second phase retarder into polarized light with opposite rotation directions, in operation, the method comprises:
• in a peep-proof display mode, inputting peep-proof display signals into pixels in the peep-proof area, and inputting compensation display signals into pixels in the compensation area, so as to allow an image displayed by the peep-proof area to be a peep-proof image and allow an image combined from an image displayed by the compensation area and the image displayed by the peep-proof area to be an interference image;
• and
• in a normal display mode, inputting first display signals into the pixels in the peep-proof area, and inputting second display signals into the pixels in the compensation area, so as to allow the image combined from the image displayed by the peep-proof area and the image displayed by the compensation area to be a normal display image.
