摘要： 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.

摘要： A liquid crystal display is provided that allows miniaturization, cost lowering, thickness reduction, and saving of unnecessary spaces of the device, and enhancement of the reliability of the device. If a variable resistor is used to set the DC potential of a VCOM potential, miniaturization of a liquid crystal display is precluded since the size of the variable resistor is large. A DA converter is used instead of a conventional variable resistor as a unit for setting (adjusting) the DC potential of a VCOM potential (counter electrode voltage), and the DA converter is formed on the same glass substrate by using the same process as those of a display area part, to thereby achieve miniaturization of the liquid crystal display.

摘要： A liquid crystal display device enabling a reduction in size and costs associated with the system as a whole, starting to display images without image distortion at power on time, and turning the screen off without image retention at power off time, a method of controlling the liquid crystal display device, and a mobile terminal incorporating the liquid crystal display device as a screen display. On a glass substrate (11) provided with a display unit (12), peripheral drive circuits such as an interface circuit (13), a timing generator (14), a reference voltage driver (15), a CS driver (18), a VCOM driver (19), and a voltage regulation circuit (20), together with a horizontal driver (16) and a vertical driver (17) are disposed. When a display reset control pulse PCI is supplied from an external source, a predetermined voltage is written into pixels while a CS voltage and a VCOM voltage adjusted to the same level as that of a pixel voltage are applied to a common-electrode-side. This allows the screen to turn white in a normally white type liquid crystal display, and to turn black in a normally black type liquid crystal display. Image distortion at power on/off time can thus be prevented.
