摘要： In a flat panel display, a display panel has a data line, a gate line and a pixel electrically connected to the data line and the gate line, and a timing controller outputs control signals and an image data signal. A data driver drives the data line in response to a portion of the control signals and the image data signal, and a gate driver drives the gate line in response to a different portion of the control signals. A control circuit controls the data driver such that the data line is maintained in a reset state for a predetermined time after a power-on is initiated. Thus, the flat panel display may prevent the display of the error-images on the liquid crystal panel.

摘要： A portable computer is provided with a sensing device which responds to absence of the computer user so that the computer system instantly goes into a power saving function that cuts off power directed to a back-light unit of the LCD display panel. The sensing device includes a sensor for sensing a computer user within the predetermined sensing range, this sensor being mounted in the housing of the flat panel display with facing the computer user, to produce a signal representative of absence of the user within the range; and a controller in response to the output signal of said sensor to produce a control signal which allows the supply power directed to the flat panel display to be interrupted. The sensing signal consists of ultrasonic wave or infrared rays. The user sensing device of the portable computer continuously monitors the computer user. If the user has left the computer, the computer system immediately goes into the power saving function that turns off the back-light unit of the LCD display panel.

摘要： A light source apparatus includes a light source module, a light sensor, a data converter, a light source controller and a light source driver. The light source module includes a light source. The light sensor generates sensing data by sensing the amount of light generated from the light source. The data converter converts the sensing data which exceeds a maximum value of reference data of a control range into converted sensing data within the control range. The light source controller generates a control signal for controlling the amount of light from the light source based upon the sensing data corresponding to no more than the maximum value or based upon the converted sensing data. The light source driver drives the light source by providing the light source with a driving signal based upon the control signal.

摘要： A tension mask frame assembly for a color cathode-ray tube, including a tension mask, a frame and a vibration prevention unit, is provided. In this tension mask frame assembly, the tension mask has a slotted portion in which a plurality of electron beam passing holes are formed and a non-slotted portion located on the edge of the slotted portion. The frame supports two facing sides of the tension mask to apply a tensile force to the tension mask. The vibration prevention unit includes a damper having first and second attenuation portions that are maintained at a predetermined angle to form an insertion portion into which the edges of the tension mask not supported by the frame are inserted, and a support member for suspending the damper from the edges of the tension mask by passing through the first and second attenuation portions and the edges of the tension mask inserted into the insertion portion formed by the first and second attenuation portions.
