Abstract: When a data processing circuit is formed on an insulating substrate by using TFTs, it is difficult to process a data signal having a high data rate, such as digital display data, at a high speed. In a data processing circuit formed on an insulating substrate by using TFTs, a data signal having a small voltage amplitude input in series is increased in level to a data signal having a large voltage amplitude by a level shift circuit (11), the serial data signal having the large voltage amplitude is converted to parallel data signals by a serial-parallel conversion circuit (12), and then, the parallel data signals are reduced in level to data signals having a small voltage amplitude by level shift circuits (13A and 13B). Therefore, high-speed processing can be applied to digital data signals at a low power consumption.

Abstract: A liquid crystal display apparatus and backlight adjustment method are provided. Backlight luminance sensors 111A to 111D are disposed in the vicinity of four outer corners of an effective screen of an LCD panel 121. Each of the backlight luminance sensors 111A to 111D detects the luminance of each of three primary colors. A backlight unit is composed of a three-primary LED array and a light diffusion unit. Transistors of the backlight luminance sensors and transistors of a pixel portion are formed on the same substrate in the same process. When a transistor is irradiated with backlight in its sufficient off region, an off current occurs due to light excitation. Since the value of the off current corresponds to the luminance of the rays of backlight that irradiates the transistor, the luminance of the backlight is detected with an output voltage into which the off current is converted. As a result, the luminance of the backlight is kept constant.

Abstract: An active-matrix-type liquid crystal display device supplies signal potentials to signal lines of a liquid crystal display panel according to a time-division drive method using time-division switches. The low-level potential of select pulses to be supplied from a select pulse generating circuit to CMOS analog switches of the time-division switches is set to be lower than the low-level potential of a signal potential output from a horizontal drive circuit. With this arrangement, even if the signal potential of a non-selected signal line is decreased due to the crosstalk of a signal potential from a selected signal line to the non-selected signal line, the generation of insufficient contrast and non-uniformity of the luminance in the horizontal direction can be prevented. As a consequence, a high image quality is maintained.
