Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

Abstract: A hinge is adapted to an electronic device having two screens. A base body of the hinge is mounted to a host base of the electronic device. The base body includes an operating portion and a linkage portion connected to each other. A first screen of the two screens is connected to the operating portion; a second screen of the two screens is connected to the linkage portion. The first screen rotates according to an operating part of the operating portion, and a driver assembly of the hinge simultaneously drives the operating portion and the linkage portion to rotate, so that the first screen and the second screen rotate simultaneously. By the simple hinge linkage structure design, the two screens rotate in opposite directions when being open, and may provide parallel slopes for viewing when being open to a preset open angle, thereby enhancing the convenience and smoothness of operation.

Abstract: A hinge includes a connecting bracket, first and second revolving axles, and first and second latches. The connecting bracket has first and second restriction blocks. The first and second revolving axles are parallel with each other and pivotally disposed on the connecting bracket. The first revolving axle has first and second cams. The first cam cooperates with the first restriction block in restricting a revolving stroke of the first revolving axle. The second revolving axle has third and fourth cams. The third cam cooperates with the second restriction block in restricting a revolving stroke of the second revolving axle. Peripheries of the first to the fourth cams respectively have a convex portion and a concave portion. The first latch is slidable between the first cam and the third cam. The second latch is slidable between the second cam and the fourth cam.

Abstract: A triaxial gear-typed hinge assembly includes a first axle, a second axle, a third axle, a first supporting component, a second supporting component, a first linking component and a second linking component. The first supporting component includes a first gear hinged to the first axle. The second supporting component includes a second gear hinged to the second axle. The first linking component includes a first linking gear and a first tube connected to the first linking gear. The first linking gear is hinged to the third axle and engaged with the first gear, and the first tube is hinged to the second axle. The second linking component includes a second linking gear and a second tube connected to the second linking gear. The second linking gear is hinged to the third axle and engaged with the second gear, and the second tube is hinged to the first axle.
