Abstract: A digital controlled multi-light driving apparatus. The driving apparatus includes a plurality of oscillation step-up circuits and a digital control circuit. The digital control circuit electrically connects to each of the oscillation step-up circuits, respectively. The digital control circuit generates sets of digital switching signals, which are phase controllable and duty cycle controllable, and respectively transmits the sets of digital switching signals to the oscillation step-up circuits. The phases and duty cycles of the digital switching signals are controlled by the digital control circuit.

Abstract: An active matrix OLED display has pixels with light emitting areas arranged in rows and columns and includes; a first pixel having a first height in the column direction and disposed in a first column of pixels and in a first row of pixels; a second pixel having a second height in the column direction and disposed in the first column of pixels and in a second row of pixels wherein the second row of pixels is adjacent to the first row of pixels and the first height being different than the second height; and a first select line arranged to drive only the first row of pixels and a second select lines spaced from the first select line arranged to drive only the second row of pixels wherein the emitting areas of the first and second pixels are disposed between the first and second select lines.

Abstract: A plasma display device is provided that can realize a stable progressive display using a plasma display panel that has a shared type arrangement form of display electrodes. A plasma display panel structure including display electrodes having a shape that has little variation of electrode area between cells and a driving sequence are combined in which the addressing step is divided into the first half and the second half. One of the first half addressing and the second half addressing is performed for a row on which the first display electrode is arranged that has an odd arrangement order when noting only the first display electrodes that are not used for row selection, and the other of the first half addressing and the second half addressing is performed for a row on which the first display electrode is arranged that has an even arrangement order.

Abstract: A light control module appropriate for an optical pointing device. The light control module comprises a processing unit outputting a first signal and a second signal, a photo sensor unit executing a capture operation according to an impulse of the first signal, and a light emitting unit executing a light emitting operation according to an impulse of the second signal, wherein when a frequency value of the first signal is less than a first preset value, at least one impulse is inserted between two successive impulses of the second signal for adjusting a frequency value of the second signal such that an equivalent frequency value corresponding to any two successive impulses of the second signal is greater than a second preset value, thus rendering flickers of the light emitting unit imperceptible.

Abstract: A haptic mouse interface system includes a mouse, a first force feedback unit for providing a first force feedback in a first direction of a virtual object to the user's hand and arm, a second force feedback unit for providing a second force feedback in second and third directions to the user's fingers, and a tactile feedback unit for providing tactile sensations to the user's fingers. The first force feedback unit has first and second encoders to receive signals relating to a first direction of the virtual object, first and second motors driven by the first and second encoders, and a linkage, which is connected between shafts of the first and second motors and the mouse. The second force feedback unit is provided in the mouse, and has a third encoder to receive a signal relating to the second and third directions of the virtual object, a third motor driven by the third encoder and having a shaft, a pair of finger pads provided at both sides of the mouse and linearly moved by the third motor.

Abstract: A system for translating a portrait-oriented software address to a portrait-oriented yet landscape-configured display address. Based on the orientation of a display device, an address translation system either passes the software address “as is” or translates the address to represent a portrait-oriented display address. A refresh address generator operates alternatively in column-forward and column-reverse modes, and additionally operates alternatively in row forward and row reverse modes to selectively rotate the image.

Abstract: A method of driving a liquid crystal display includes arranging an externally provided first data into a histogram for each frame, producing a second data having an expanded contrast using the histogram, determining a control value by extracting a peak value at a position where brightness components are concentrated in a distribution, and controlling a brightness of a back light in accordance with a gray level of the control value.
