摘要:
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.

This disclosure relates to a method for preparing N,N′-dimethyl-3,3′-dithiodipropionamides, which is an intermediate compound used for preparation of substituted 3-isothiazolones, including reacting 3,3′-dithiopropionic acid alkyl ester with an alkylamine at a temperature of from 0 to 50° C. in the presence of a polar solvent.
摘要:
A display apparatus includes a display panel for display an image, a camera module and a receiving container. The camera module includes a lens part mounted on a printed circuit board. The receiving container includes a main receiving space receiving the display panel and a sub receiving space extended from the main receiving space and receiving the camera module.
摘要:
A liquid crystal display (“LCD”) device includes an LCD panel, a data driver and a gate driver. The LCD panel includes a first pixel section and a second pixel section formed in regions defined by a adjacent gate lines and adjacent data lines. The first pixel section is electrically charged at a first time point and the second pixel section is electrically charged at a second time point later than the first time point. The data driver provides the data lines with data voltages. The gate driver applies a first gate signal to the first pixel section, and a second gate signal having at least one different characteristic from that of the first gate signal to the second pixel section. Therefore, vertical flickering may be prevented in the LCD device.
