摘要： A liquid crystal display device capable of controlling a viewing angle is disclosed.The liquid crystal display device includes: a liquid crystal panel configured to include a plurality of quad type pixels each consisted of red, green, blue, and viewing angle control sub-pixels; and a timing controller configured to reply to a viewing angle mode selected by a user and apply red, green, and blue data and any one of a wide viewing angle control data, a first narrow viewing angle control data, and a second narrow viewing angle control data to the liquid crystal panel.As such, the LCD device controls a range of viewing angles, thereby allowing the image to be viewed from every direction or not to be viewed from the left and right directions or the upward diagonal directions in the center of the user. In other words, the LCD device can limit the image display according to the positions of the persons adjacent to the user. Therefore, the user using the LCD device can adjust it to freely share information or to limit its range with adjacent persons. Furthermore, the LCD device can enhance information reliability and security.

摘要： A charge characteristic compensating circuit for a liquid crystal display panel for maintaining a charge characteristic of the liquid crystal display panel independently of ambient temperature change to prevent deterioration of images displayed. A plurality of liquid crystal cells control light transmission in response to data signals from the data lines. A plurality of thin film transistors switch the data signals from the data lines to the liquid crystal cells in response to signals on the gate lines. A voltage supply generates a gate voltage required for the gate lines. A gate line driver applies the gate voltage from the voltage supply to the gate lines to drive the gate lines. A gate line controller responds to a change in the ambient temperature to vary a controlling signal applied to the gate line driver.

摘要： A liquid crystal display device and a driving method thereof wherein a change in a charge rate of a thin film transistor compensates for an externally applied frequency variation upon driving of the liquid crystal display device so as to improve the picture quality. In the device, a timing controller receiving control signals from a host system. A frequency detector is connected to either the input terminal or the output terminal of the timing controller to detect the control signals. A compensation voltage setting part compensates for the driving voltage in response to the control signals detected from the frequency detector so as to adjust a charge time of each thin film transistor. A voltage converter generates a compensation voltage set by the compensation voltage setting part to deliver the compensation voltage to a liquid crystal display panel. Accordingly, the common voltage and/or the gate high voltage, changed in accordance with an extremely applied frequency variation, are set to optimum values and thus are compensated so that a constant picture quality can be maintained irrespectively of such a frequency variation.
