摘要： An optical device is provided. The optical device includes a main body; a display unit which includes a polarization layer and which is disposed on one surface of the main body; and a camera module which is disposed in the main body and which overlaps the polarization layer in an optical axis direction. A first region of the polarization layer overlapping the camera module in the optical axis direction blocks or reflects at least some incident light when the camera module is not operated.

摘要： A micro-OLED display includes a substrate with a coating made of IR-transparent material such as Zinc Selenide or Zinc Sulfide to allow a pupil tracking camera, which may include photodiodes, to be mounted directly behind the display. The coating is transparent to near infrared (NIR) radiation but opaque to visible light.

摘要： The present disclosure provides a display panel, a display device and a display driving method. The display panel includes a first display region and a second display region each including a plurality of pixel repeat units. Each pixel repeat unit includes a first sub-pixel in a first color, a second sub-pixel in a second color, a third sub-pixel in a third color and a fourth sub-pixel in the first color. A light-emitting area of each of the first sub-pixel and the fourth sub-pixel is smaller than that of the second sub-pixel or the third sub-pixel. A dummy pixel space is formed in a second pixel row between a first pixel repeat unit in a first pixel row and a second pixel repeat unit in a third pixel row in three adjacent pixel rows at the second display region.

摘要： In a display driver circuit, a push-pull circuit is coupled to an internal circuit, a first external power terminal, a second external power terminal and a target node respectively, and can control the on-off of the first external power terminal, the second external power terminal and the target node in response to a target control signal transmitted by the internal circuit. The switching circuit is coupled to the target node and the I/O interface of the display driver circuit respectively, and can transmit an electric potential of the target node to the I/O interface of the display driver circuit, that is, a first power signal transmitted from the first external power terminal to the target node or a second power signal transmitted from the second external power terminal to the target node is further output to the I/O interface.

摘要： A pixel driving circuit includes a driving control sub-circuit and a time control sub-circuit. The driving control sub-circuit includes a first driving sub-circuit. The first driving sub-circuit is configured to output a driving signal to drive an element to be driven to operate. The time control sub-circuit includes a second driving sub-circuit. The second driving sub-circuit is configured to output a third voltage signal to make the first driving sub-circuit stop outputting the driving signal, so as to control operating duration of the element to be driven.
