Publication number: 20240065057Abstract: A display may include pixels arranged in rows and columns in an active area and display driver circuitry in an inactive area. Data lines for the pixels may be positioned in the active area. Fanout lines may be routed through the active area. Each fanout line may electrically connect the display driver circuitry to a respective data line. One or more pixels may include a drive transistor and a light-emitting diode that are connected in series between a first power supply terminal and a second power supply terminal. A conductive layer may form a first terminal (such as the source terminal, the gate terminal, or the drain terminal) for the drive transistor. A conductive shielding layer may be interposed between the conductive layer and a fanout line to mitigate capacitive coupling between the terminal of the drive transistor and the fanout line.Type: ApplicationFiled: June 2, 2023Publication date: February 22, 2024Inventors: Shin-Hung Yeh, Abbas Jamshidi Roudbari, Chien-Ya Lee, I-Cheng Shih, Shyuan Yang, Tsung-Ting Tsai

Publication number: 20240061298Abstract: To minimize the width of a non-light-emitting border region around an opening in the active area, data lines may be stacked in the border region. Data line portions may be formed using three metal layers in three different planes within the border region. A metal layer that forms a positive power signal distribution path in the active area may serve as a data line portion in the border region. A metal layer may be added in the border region to serve as a data line portion in the border region. Data line signals may also be provided to pixels on both sides of an opening in the active area using supplemental data line paths. A supplemental data line path may be routed through the active area of the display to electrically connect data line segments on opposing sides of an opening within the display.Type: ApplicationFiled: October 26, 2023Publication date: February 22, 2024Inventors: Shin-Hung Yeh, Warren S.

Patent number: 11762490Abstract: An electronic device may have a display with an active area configured to display images and an inactive area that is free of pixels and that does not display images. Touch sensor sense lines may have portions located in the active area and portions located in the inactive area. The active and inactive areas may be characterized by respective reflectivity values. To match the reflectivities of the active and inactive areas and thereby avoid undesired visually distinguishable differences in the appearances of these areas, the touch sensor circuitry in the inactive areas may be configured to match the reflectivity values of the active and inactive areas. Sense line portions in the inactive area may have metal traces of enhanced reflectivity and/or uneven surface topology to enhance ambient light reflections through a circular polarizer that overlaps the active and inactive areas.Type: GrantFiled: August 20, 2021Date of Patent: September 19, 2023Assignee: Apple Inc.Inventors: Kyounghwan Kim, Abbas Jamshidi Roudbari, Chia-Hsiang Chen, Chien-Ya Lee, Ching-Sang Chuang, Jae Won Choi, Jonathan H.

Patent number: 11741904Abstract: A display may have rows and columns of pixels. Gate lines may be used to supply gate signals to rows of the pixels. Data lines may be used to supply data signals to columns of the pixels. The data lines may include alternating even and odd data lines. Data lines may be organized in pairs each of which includes one of the odd data lines and an adjacent one of the even data lines. Demultiplexer circuitry may be configured dynamically during data loading and pixel sensing operations. During data loading, data from display driver circuitry may be supplied, alternately to odd pairs of the data lines and even pairs of the data lines. During sensing, the demultiplexer circuitry may couple a pair of the even data lines to sensing circuitry in the display driver circuitry and then may couple a pair of the odd data lines to the sensing circuitry.Type: GrantFiled: March 19, 2021Date of Patent: August 29, 2023Assignee: Apple Inc.Inventors: Ting-Kuo Chang, Abbas Jamshidi Roudbari, Tsung-Ting Tsai, Warren S.

Patent number: 9576517Abstract: A shift register includes a plurality of shift register circuits. Each of the shift register circuits includes a first switch, an input circuit, a pull-down circuit and a ripple reduction circuit. The first switch is used to output a scanning signal of the shift register circuit according to voltage levels of a node and a clock signal. The input circuit is used to pull up the voltage level of the node according to a scanning signal of a previous shift register circuit. The pull-down circuit is used to pull down the voltage levels of the node and the scanning signal of the shift register circuit according to a scanning signal of a following shift register circuit. The ripple reduction circuit is used to suppress ripples on the voltage levels of the node and the scanning signal caused by the coupling effect of the clock signal.Type: GrantFiled: December 27, 2014Date of Patent: February 21, 2017Assignee: AU OPTRONICS CORP.Inventors: Wei-Chu Hsu, Man-Wen Shih, Ya-Ling Chen, Chien-Ya Lee
