  • Patent number: 11626053
    Abstract: A display device includes a display panel, a display panel driving circuit, and a power management integrated circuit that generates driving voltages, receives driving set data from a timing controller, stores driving hex values corresponding to the driving set data in first internal registers, and determines voltage levels of the driving voltages based on the driving hex values. The power management integrated circuit divides the driving hex values into upper and lower decimal values, derives a result decimal value by applying the upper and lower decimal values to a first authentication-formula, generates a result hex value based on the result decimal value, compares an authentication hex value corresponding to authentication data received from the timing controller with the result hex value, and selectively operates in a normal mode or in a protection mode based on a comparison result between the authentication hex value and the result hex value.

  • Patent number: 11619851
    Abstract: 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.

  • Patent number: 11614839
    Abstract: In some examples, a touch screen can include touch electrodes that can function as drive (Tx) electrodes and sense (Rx) electrodes during a touch sensing operation of the electronic device. The drive electrodes can include +Tx electrodes and ?Tx electrodes that can receive drive signals that can have the same amplitude and frequency and opposite phases, for example. In some examples, the surface areas of the +Tx electrodes and the ?Tx electrodes can be the same and the distances of the +Tx electrodes and ?Tx electrodes from the Rx electrodes can be different. In some examples, the total charge coupled to a proximate or touching object can be zero, which can mitigate problems associated with ungrounded or poorly grounded objects in contact with the touch screen.

  • Patent number: 11594190
    Abstract: A display may have an array of pixels such as liquid crystal display pixels. The display may include short pixel rows that span only partially across the display and full-width pixel rows that span the width of the display. The gate lines coupled to the short pixel rows may extend into the inactive area of the display. Supplemental gate line loading structures may be located in the inactive area of the display to increase loading on the gate lines that are coupled to short pixel rows. The supplemental gate line loading structures may include data lines and doped polysilicon that overlap the gate lines in the inactive area. In displays that combine display and touch functionality into a thin-film transistor layer, supplemental loading structures may be used in the inactive area to increase loading on common voltage lines that are coupled to short rows of common voltage pads.

  • Patent number: 11573302
    Abstract: Disclosed are Geiger-mode avalanche-photodiode-based LiDAR systems and methods that interrogate a detection region with a periodic series of optical pulses whose reflections are detected via a receiver comprising multiple Geiger-mode avalanche-photodiode-based pixels. The pixels of the receiver are configured to asynchronously disarm and rearm after absorption of a reflection. As a result, each pixel can detect multiple reflections of the same optical pulse during a single detection frame whose duration is defined by the periodicity of the series of optical pulses. Furthermore, each pixel can store time-of-flight data for each of multiple reflections detected during a detection frame. Each individual pixel of the receiver, therefore, is not blinded and inoperative for the remainder of a detection frame once it detects a first reflection.
