  • Patent number: 11822756
    Abstract: In a liquid crystal display (LCD) device having a touch panel function, power consumption is reduced in the standby state. The display section is divided into blocks each of which is formed of a plurality of display lines. The counter electrode is disposed for each block. A driving circuit selectively supplies, to the counter electrode of each block, the voltage used for the liquid crystal display and the voltage used for the touch panel scanning. The driving circuit has a source amplifier that supplies the video voltages to the video lines. The driving circuit reduces the current in the source amplifier, such that the current is lower than current at the time of a normal operation, to lower the power consumption, and stops the operation of the source amplifier and supplies the GND voltage to the video lines to further lower the power consumption.

  • Patent number: 11809667
    Abstract: A transparent conductive substrate structure used for a thermoforming process includes a transparent cover plate and a touch sensing layer structure. The transparent cover plate includes a toughening layer on one side thereof. The touch sensing layer structure arranged on one surface of the toughening layer, and includes a first transparent conductive layer, a dielectric layer, a barrier layer, a second transparent conductive layer, and a buffer protective layer. Each transparent conductive layer is directly applied to the transparent cover plate, so that the thickness between the transparent conductive layers is below 1 ?m. The thickness between layers may be reduced to increase the sensitivity of the touch sensing layer structure. To prevent each transparent conductive layer and an electrode wire layer from breaking during the thermoforming process, the transparent conductive substrate structure is combined with the buffer protective layer to strengthen the structure of each transparent conductive layer.

    Abstract: In some exemplary processes for controlling an external device using a computer-generated reality interface, information specifying a function of the external device is received from the external device. First image data of a physical environment that includes the external device is obtained with one or more image sensors. A representation of the physical environment according to the first image data is displayed on a display. While displaying the representation of the physical environment, second image data identifying a gesture occurring between the display and the external device in the physical environment is obtained with the one or more image sensors. A determination is made as to whether the identified gesture satisfies one or more predetermined criteria associated with the function. In accordance with determining that the identified gesture satisfies one or more predetermined criteria associated with the function, the external device is caused to perform the function.
