    Abstract: This present invention relates to a method for driving a circuit of a field emission backlight panel. A group of driving signals with phase shift is sent to a plurality of emitters of a field emission display panel to control the emitters to emit electrons alternately. Therefore, the lighting area of the field emission display panel is increased, and so are the brightness and the uniformity thereof.

  • Publication number: 20080266239
    Abstract: A control unit controls brightness of a liquid crystal display unit such that the brightness becomes darker as a distance between an electronic view finder and an operator measured by a distance measuring sensor becomes shorter. With this structure, even if the operator takes his or her eye off from the electronic view finder, the liquid crystal display unit is not switched from an OFF state to an ON state. Therefore, it is possible to prevent the brightness of the liquid crystal display unit from becoming burdensome to an operator when the eye of the operator approaches the electronic view finder.

    Abstract: An apparatus for contrast control and an associated method are provided. The apparatus can adjust the backlight brightness for a white or black frame to enhance the contrast of a display device, and keep the backlight brightness at a suitable level for other frames to avoid lowering the contrast of a single frame. The apparatus includes a frame detection unit and a backlight control unit. The frame detection unit detects whether an input frame is a white or black frame, and outputs a corresponding detection signal; the backlight control unit generates a backlight control signal according to the detection signal, thereby controlling the brightness of a backlight source of the display device.

  • Publication number: 20080266244
    Abstract: A dual-sided electrophoretic display (700) having a first region (701) and a second region (702) is provided. Each of the first region (701) and the second region (702) includes selectively operable members (703,704) that function as pixels for presenting images on the electrophoretic display (700). Each of the selectively operable members (703,704) is driven by a driver circuit (710) by way of corresponding thin film transistors and capacitors (742,742), which are opaque. As the selectively operable members (704) of the second region (702) are bigger than are the selectively operable members (703) of the first region (701), the aperture ratio of the selectively operable members (704) of the second region (702) is greater than in the first region (701) when viewed from the rear side (730). Thus, a contrast ratio of the second region (602), when viewed from the rear side (730) is sufficiently high that text, icons, and characters presented in the second region (602) are legibly visible on the rear side (730).

  • Publication number: 20080266276
    Abstract: A display apparatus including a display driver. The data driver includes a converter to receive and convert image data in digital form into data voltages in analog form, and to provide the data voltages to output buffers. The output buffers receive and buffer the data voltages based on bias voltages generated as part of a feedback path between a bias voltage control circuit and the output buffers. The data voltages are provided to a display part. Before the data voltages output from the output buffers are provided to the display part, the bias voltage control part receives data voltage from the output buffers to count a slew rate of the data voltage, and varies the voltage level of the bias voltage based on the counted result of the slew rate, thereby providing feedback to the output buffers. Accordingly, differences of the slew rate between the data voltages output from the output buffers may be decreased.

  • Publication number: 20080266282
    Abstract: A light emitting display includes a substrate, a pixel area, a first power source line to supply a first power signal to each pixel on a first side of the pixel area, a second power source line to supply the first power signal to each pixel on a second side of the pixel area, and an impedance compensator for compensating a difference in a voltage drop between the first power source line and the second power source line. A voltage drop caused by line resistance that depends on the length of the first and second power source line that supply the first power signal to a lower and upper side of a pixel area, respectively, is equalized, thereby minimizing the voltage drop of the first power signal supplied to all pixels, and minimizing non-uniformity of brightness due to the voltage drop differences at each pixel.

    Abstract: An LED driving circuit that can improve characteristics is provided. An LED driving circuit 10 has first and second peaking current generating circuits 10e (second current source) and 10f (third current source), and a timing generating circuit 10b provides driving signals T2 and T3 to transistors 10c so that first and second peaking currents are supplied from the first and second peaking current generating circuits 10e and 10f to an LED 11. In this case, a driving current is made sharp in rise and rounding of the LED emission output that accompanies the driving current can be corrected. Also, although when there is only one peaking current, a depression tends to be formed when the peaking current is added to a main current, when two or more peaking currents are added in accordance with the main current, the depression can be reduced significantly, and stable optical communications can thereby be performed.
