摘要： A display device is provided and includes a first photosensor that detects the light amount of ambient light of a display area, a second photosensor that detects dark current arising when light is blocked, and changeover switches that select the first photosensor and the second photosensor. The display device further includes a comparator that compares the output of the selected first photosensor or second photosensor with a predetermined reference value, and control means that calculates the difference between the comparison result by the comparator with the first photosensor and the comparison result by the comparator with the second photosensor and controls the amount of light supplied to the display area corresponding to the calculation result. This configuration suppresses the influence of a detection error due to variation in the performance between the photosensors applied to the display device to thereby accurately adjust the amount of light supplied to the display area.

摘要： An active-matrix liquid crystal display device has pixels arranged in a matrix which each include a thin film transistor (TFT) as an active element. When the device is in a power-off state, TFTs in all the pixels are switched on, and all horizontal switches are turned on so that all data lines are supplied with a potential equal to the potential of common electrodes of the pixels. This forms a discharging path for discharging residual charge in all the pixels, and the discharging path can instantaneously discharge the residual charges.

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.
