    摘要: A display apparatus includes a display panel that displays an image using a first light, a light guide part positioned at a front side of the display panel, a backlight unit, an image information collecting part, and a processing part. The light guide part emits a second light different from the first light and guide the second light, and the backlight unit is positioned at a rear side of the display panel to provide the first light to the display panel. The image information collecting part photographs the light emitted from the light guide part to output image information. The processing part processes the image information to generate a coordinate value of a position at which an object provided on the light guide plate is positioned.

    摘要: A display apparatus includes a display panel, a backlight unit, a backlight control circuit, sensors, a read-out circuit and a sensor auxiliary circuit. The display panel includes pixels and displays an image. The backlight unit includes a first light source which emits a first light in a infrared light range. The backlight control circuit controls a brightness of the first light source. The sensors sense an external signal and outputs first sensing signals. The read-out circuit outputs the first sensing signals as second sensing signals. The sensor auxiliary circuit compares a maximum value and a minimum value of the second sensing signals and provides a brightness control signal to the backlight control circuit based on the compared difference to control the brightness of the first light source.

    摘要: An impulsively driven liquid crystal display includes a display panel displaying an image in response to a gate signal and a data signal, a panel driving circuit providing the gate signal and the data signal to the display panel using an image signal and a control signal, a backlight unit including a plurality of light sources that blink at once to provide a light to the display panel, and a backlight control circuit. The backlight control circuit automatically detects an existence of text information from a received image signal, and if the text is detected to be present, adjusts the blinking timing of the light sources to correspond with the area on the display panel where the text will be displayed, the adjustment being a function of a liquid crystal response delay time of liquid crystals used in the display panel.

    摘要: The present invention relates to a power supply device for a backlight and a liquid crystal device using the power supply device. The power supply device and the liquid crystal display device using the same according to the present invention can drive a fluorescent lamp while keeping luminance of the fluorescent lamp constant by applying voltages with different polarities to both ends of the fluorescent lamp, detecting a voltage proportional to a current flowing through the fluorescent lamp, and causing the detected voltage to be fedback. Therefore, there are advantages in that since a leakage current between the fluorescent lamp and a reflector is reduced, the luminance of the fluorescent lamp becomes uniform and the life of the fluorescent lamp is prolonged.
