Abstract: A circuit board for a display apparatus includes a substrate, a plurality of light-emitting elements arranged substantially in a line on the substrate, and a plurality of branch lines connecting the light-emitting elements to each other in series. A first group of the plurality of branch lines is formed on a first side of the line of the plurality of light-emitting elements, and a second group of the plurality of branch lines is formed on a second, opposing side of the line of the plurality of light-emitting elements.

Abstract: Provided is a liquid crystal display (LCD) in which warping of a liquid crystal panel-driving printed circuit board (PCB) is reduced. The LCD includes: a liquid crystal panel; a lower housing which accommodates the liquid crystal panel; a lamp-driving PCB fixed to the lower housing; a reinforcing member which has one end fixed to at least one surface of the lamp-driving PCB and another end separated from the lamp-driving PCB; and a liquid crystal panel-driving PCB which includes a circuit-mounting board disposed outside the lower housing, wherein at least part of the circuit-mounting board is inserted between the lamp-driving PCB and the reinforcing member, so as to be at least partially supported by the lamp-driving PCB and the reinforcing member.

Abstract: A display that has rush current reduction during power-on is provided. A display panel that displays an image includes a gate line and a data line. A voltage generator receives a supply voltage and outputs a gate-on voltage and a gate-off voltage to first and second output nodes, respectively. The voltage generator includes a pull-up capacitor that is charged for a first time period of a power-off period and is discharged for a second time period of the power-off period to increase a voltage level of the second output node, the first and second time periods being consecutive periods of the power-off period. A gate driver selectively applies a gate-on voltage or a gate-off voltage to the gate lines, and a data driver applies a data voltage to the data line.

Abstract: A display apparatus includes a backlight assembly generating a light; a sensor sensing an amount of the light and color coordinates of the light to generate sensing information; a display panel receiving the light and displaying an image in response to a gray-scale voltage; a gray-scale compensation unit receiving M-bit source data and compensating a gray-scale of the source data in response to the sensing information to generate N-bit first compensation data; and a data driver converting the first compensation data into gray-scale voltage and proving the gray-scale voltage to the display panel.

Abstract: The present invention applies different common voltages to common electrodes corresponding to both end points of gate lines and data lines. At this time, the highest common voltage is applied to a common electrode point far away from both a data driver and a gate driver, the second highest common voltage is applied to a common electrode point close to the data driver and far away from the gate driver, the third highest common voltage is applied to a common electrode point far away from the data driver and close to the gate driver, and the lowest common voltage is applied to a common electrode close to both of the data driver and the gate driver.

Abstract: A channel selection apparatus is provided for allowing receipt of signals broadcast according to the NTSC, SECAM and PAL broadcast modes. A controller discriminates the signal's broadcast mode based on the horizontal sync signal included in the received signal and alters a circuit connection path. Accordingly, a desired broadcast mode can be automatically selected without requiring any particular switch manipulation by a user. Further, a video signal processing path is separated from a sound signal processing path, in order to obtain excellent sound quality, even when receiving a stereo broadcast. Also, it is possible to easily automate the manufacturing process for the apparatus, thereby improving productivity.
