Abstract
A wearable display apparatus comprises a control unit, a display unit, an optical transmission unit and a photoelectric detection unit. The control unit is configured to control the display unit to output a display image, the light transmission unit is configured to transmit a first part of light of the display image to human eyes, and transmit a second part of the light of the display image to the photoelectric detection unit, the photoelectric detection unit is configured to send a feedback signal to the control unit; and the control unit is configured to compensate for a drift of characteristics including brightness and color according to the feedback signal from the photoelectric detection unit.
Claims11
A wearable display apparatus comprising:
- a control unit;
- a display unit comprising a plurality of light-emitting elements and electrically connected to the control unit;
- a light transmission unit;
- and
- a photoelectric detection unit electrically connected to the control unit;
- wherein the control unit is configured to control the display unit to output a display image;
- wherein the light transmission unit comprises a reflector or a diffractive coupler, and wherein the reflector or the diffractive coupler is configured to transmit a first part of light of the display image to human eyes, and transmit a second part of the light of the display image to the photoelectric detection unit;
- wherein the photoelectric detection unit is configured to send a feedback signal to the control unit after detecting the second part of the light;
- and
- wherein the control unit is configured to compensate for drift of characteristics including brightness and color according to the feedback signal from the photoelectric detection unit.
A driving method of a wearable display apparatus, the wearable display apparatus comprising a control unit, a display unit comprising a plurality of light-emitting elements and electrically connected to the control unit, a light transmission unit comprising a reflector or a diffractive coupler, wherein the reflector or the diffractive coupler is configured to transmit a first part of light of a display image to human eyes, and transmit a second part of the light of the display image to a photoelectric detection unit, and the photoelectric detection unit electrically connected to the control unit, the driving method comprises:
- controlling, by the control unit, the display unit to output a display image according to initial settings;
- acquiring, by the photoelectric detection unit, image information of the display image at set time intervals, and sending, by the photoelectric detection unit, a feedback signal comprising the image information to the control unit;
- and
- comparing, by the control unit, the feedback signal from the photoelectric detection unit and an initial signal of the photoelectric detection unit, calculating, by the control unit, a drift amount of characteristics including brightness and color, and compensating, by the control unit, for a drift of subsequent display images when the drift amount is greater than a preset threshold.
