  • Patent number: 11016621
    Abstract: A capacitive touch screen, having a first transparent substrate provided with a touch circuit layer. The touch circuit layer is provided with first and second electrodes and a jumper portion. The touch screen is further provided with an insulating layer. The insulating layer is continuously disposed in an entire transparent touch area of the touch screen, and is provided with through holes at the jumper portion to form a jumper connection of the second electrode. The touch screen further includes a shielding layer sandwiched between the first transparent substrate and the touch circuit layer, and contains multiple shielding blocks. The shielding blocks correspond to the through holes, and the contours of the shielding blocks are formed by expanding the contours of the through holes outwards. The capacitive touch screen can effectively reduce side light reflection on an edge slope of the insulating layer, thereby avoiding interference with display.

  • Patent number: 8928627
    Abstract: A light sensing circuit using an oxide semiconductor transistor, a method of manufacturing the light sensing circuit, and an optical touch panel including the light sensing circuit. Because the light sensing circuit includes only one light sensor transistor and one switch transistor formed on the same substrate, a structure of the light sensing circuit is simplified. Furthermore, because the light sensor transistor and the switch transistor have the same structure, a method of manufacturing the light sensing circuit is also simplified. Also, since an optical touch panel or an image acquisition apparatus using the light sensing circuit uses the light sensing circuit having a simple structure and does not use a capacitor, the optical touch panel or the image acquisition apparatus may be made thinner and larger.

  • Patent number: 8854325
    Abstract: An electronic device and method are provided for rotating an object displayed at or by the device. The object may be an entire displayed region of a display screen, such as a window, frame, or other region or subregion, or a block element or other type of content component such as an image or map. A first input defining a reference point for the object is detected at a first user interface mechanism. After commencement of the detected first input, a second input at a second user interface mechanism, such as a touchscreen display, is detected. In response to the second input, a rotation transformation is applied to the object, the rotation transformation center being defined by the reference point, and the rotation transformation angle being defined by the second input. The object may be displayed by the touchscreen display, or by a display device external to the electronic device.

  • Patent number: 8816968
    Abstract: Reducing energy usage by a monitor includes a map manager between a monitor interface and a processor that divides a display area of a monitor into areas and stores display information in a staging area. The map manager distinguishes an active window selected by a user from the remainder inactive, unselected areas of a display, and further determines a used subset of areas within the active window distinguished from the remainder unused areas as a function of a user preference. Accordingly, the map manager drives the monitor at each of the used area active window areas with the processor display information stored in the staging area at a normal luminance specified by the processor display information, and at each of the remainder unused, inactive and unselected areas of the total display area at a reduced luminance lower than the specified normal luminance.
