  • Patent number: 11599224
    Abstract: Disclosed herein are electronic devices having touch input surfaces. A user's touch input or press on the touch input surface is detected using a set of lasers, such as vertical-cavity surface-emitting lasers (VCSELs) that emit beams of light toward the touch input surface. The user's touch causes changes in the self-mixing interference within the VCSEL of the emitted light with reflected light, such as from the touch input surface. Deflection and movement (e.g., drag motion) of the user's touch is determined from detected changes in the VCSELs' operation due to the self-mixing interference.

  • Patent number: 11588977
    Abstract: The present disclosure describes a method and apparatus that can be used to adjust for distorted ambient light readings caused by the ambient light sensor being located behind the display screen. The strategy of the disclosure relies, at least in part, on spectral decomposition of ambient light measurements into independent sources (e.g., red, green, and blue display components of an Organic Light Emitting Diode (“OLED”) display screen and ambient light). Following the spectral decomposition technique, a more accurate ambient light measurement can be obtained in some instances. This technique enables determinations such as ambient lux and correlated color temperature independent of the content displayed on the screen.

  • Patent number: 11557251
    Abstract: The present application discloses a current-driven display device capable of providing satisfactory display without flickering even when pause drive is performed. In a pixel circuit 15, a first initialization transistor T4 initializes a gate voltage Vg, and thereafter a voltage on a data signal line Di is written to a holding capacitor Cst via a write control transistor T2 and a drive transistor T1. Thereafter, emission control transistors T5 and T6 are turned on, so that a drive current I1 from the drive transistor T1 causes an organic EL element OL to emit light. During this emission period, even if the gate voltage Vg is decreased due to a leakage current through the first initialization transistor T4 in an OFF state, the decrease is compensated for by increasing a threshold control voltage being provided to a threshold control terminal TG of the drive transistor T1.
