  • Patent number: 6982691
    Abstract: There is provided a method of driving a cholesteric liquid crystal display (LCD) panel by sequentially applying a selection line voltage to individual scan electrode lines and simultaneously applying data signals to all data electrode lines in order to select a state of each cholesteric liquid crystal cell according to a given gray scale level. Each selection time, during which the selection line voltage is applied to a certain scan electrode line and simultaneously the data signals are applied to all of the data electrode lines, is constant. Each selection time is divided into a first part time and a second part time. A low selection line voltage is applied to a relevant scan electrode line during the first part time. A high selection line voltage having a level different from that of the low selection line voltage is applied to the relevant scan electrode line during the second part time.

  • Patent number: 6980194
    Abstract: A level shifter includes first and second P-type TFTs for latching a level of first and second output nodes, first and second N-type TFTs for setting the level of the first and second output nodes, and a drive circuit. The drive circuit includes third to eighth N-type TFTs providing, in response to rising and falling edges of an input signal, a voltage higher than a threshold voltage of the first and second N-type TFTs, between the gate and source of the first and second N-type TFTs, and includes first and second capacitors and a resistor element. Accordingly, even if an amplitude voltage of an input signal is smaller than the threshold voltage of the first and second N-type TFTs, the level shifter operates normally.

  • Patent number: 6977642
    Abstract: A back light is provided with light sources, lighting control circuits for lighting the light sources, respectively, and a brightness control circuit for outputting light volume adjusting signals to the lighting control circuits, respectively. The brightness control circuit receives a luminance adjusting signal, adjusts only a part of the light volume adjusting signals, and fixes output of the rest of the light volume adjusting signals. The lighting control circuits apply voltages corresponding to the light volume adjusting signals to the light sources, thereby adjusting the light sources in luminance. The light volume adjusting signals can be adjusted one by one, which facilitates luminance adjustment. Thus, by lighting only one light source at the minimum luminance, the screen brightness of the liquid crystal display having this back light can be lowered to an appropriate level when it is used in dark places.

  • Patent number: 6975302
    Abstract: A ballistics subsystem is coupled to a force sensor of an isometric input device. The ballistics subsystem augments control by applying a dual gain transfer function that smoothly transitions from separate gain factors for low and high force inputs. When applied in a cursor device, such as a joystick or force pad, pointer movement is coupled to input force, not input displacement. Traditionally, an array of miniature strain gauges is used to measure the input force. A more recent method optimized for very low cost uses an array of capacitive sensors. Regardless of what physical mechanism is used to measure input force, customized algorithms are generally used to establish the feel and usability of an isometric joystick. The invention comprises several new methods for optimizing the use of an isometric joystick as a cursor-positioning device, altering the transfer function gain to take advantage of asymmetry, detecting selection and deselection, and combined selection and deselection.

  • Patent number: 6967639
    Abstract: An image display device, a scan line drive circuit and a driver circuit for the display device capable of driving the display device having a multiplex pixel structure by simple control and utilizing a simplified gate driver. The image display device includes a plurality of pixel electrodes, a plurality of scan lines G for supplying scan signals to turn on and off these pixel electrodes, a pulse generator for generating a shift pulse, buffers B provided corresponding to the respective scan lines G, and a shift register unit in which first and second shift registers SR1 and SR2 are alternately cascade-connected. The shift pulse is propagated through the first and the second shift registers SR1 and SR2 by outputting the shift pulse from the pulse generator to the shift register unit. In this way, the shift pulse is controlled to be propagated between a buffer B to an adjacent buffer B in one horizontal scanning cycle.

  • Patent number: 6961045
    Abstract: This invention relates generally to image projection methods and apparatus for creating color or gray scale images using spatial light modulators (SLMs) without color or gray capability. The basic concept is to divide the pixels on a single SLM into multiple groups and then illuminate each group with a different primary color. The content of the single SLM panel can then be programmed as if there are multiple sub-panels illuminated with different primary colors. The combined image on the single panel therefore displays images of many colors. Illumination can be achieved by projection of a pattern of color or gray scale distribution to the surface of the SLM panel and registering the pattern to corresponding pixel groups; or can be implemented by applying a proximity pattern close to the SLM surface. This technique can be applied to volumetric 3D displays, 2D displays, and optical correlators.

  • Patent number: 6919870
    Abstract: The objective of this invention is to compensate or avoid the influence of offset in an easy and efficient manner, to correctly match the voltage of the output signal with the voltage of the input signal, that is, the target value, and to significantly reduce the current consumption. When voltage follower 32L supplies bias voltage VBn to each of constant current source circuits 58L, 60L, it acts as a source-type voltage follower. However, when the bias voltage applied to each of constant current source circuits 58L, 60L is changed from VBn to Vss of the power supply voltage level, each of constant current source circuits 58L, 60L is turned off, and no current flows through them. When the constant current source circuit 58 is turned off in differential input part 44L, the potential at the output terminal (node) NL rises almost to the level of the power supply voltage Vdd. In this way, the driving transistor 62L is also turned off in output part 46L.
