  • Publication number: 20230371322
    Abstract: A method of fabricating a display panel including a display region having a first pixel region where pixels are disposed, and a sensing region having a second pixel region where pixel groups are disposed and a light transmitting part disposed between the pixel groups, is discussed. The method can include forming a light shield layer at least in the sensing region, wherein the light shield layer includes an opening hole corresponding to the light transmitting part and exposes the light transmitting part to a laser beam through the opening hole. The method can further include forming a metal layer spaced apart from the light blocking layer in the first pixel region of the display region and the sensing region, and irradiating the laser beam to at least the sensing region to remove the metal layer from the light transmitting part.

  • Patent number: 11793047
    Abstract: Provided is a display panel including a display area including a first pixel region in which a plurality of pixels are disposed and an image-capturing area including a second pixel region in which a plurality of pixel groups are disposed and a plurality of light-transmitting portions are disposed between the pixel groups. The light-transmitting portions are disposed along virtual spiral reference lines which spirally extend outward from the center of the image-capturing area, and sizes of the light-transmitting portions increase as a distance from the center of the image-capturing area increases.

  • Publication number: 20230061983
    Abstract: A display apparatus may include at least one switching thin film transistor and a driving thin film transistor, which are disposed on a device substrate. The driving thin film transistor may include a driving semiconductor pattern made of an oxide semiconductor. A light-blocking pattern may be disposed between the device substrate and the driving semiconductor pattern. The light-blocking pattern may be disposed close to the driving semiconductor pattern. Thus, in the display apparatus, a current variation value according to a voltage applied to the driving gate electrode of the driving thin film transistor may be reduced, without changing the characteristics of the switching thin film transistor. Thereby, in the display apparatus, the occurrence of a spot in low grayscale may be prevented.
