Abstract: A liquid crystal display device includes a display part which has a plurality of divided segments and a control part, configured to control voltages applied to the segments. The control part changes a turning-on pattern of segments to be output to the display part from a first turning-on pattern which turns on a first segment group to a second turning-on pattern which turns on a second group, and subsequently to a third turning-on pattern which turns on a third segment group. Change of the turning-on pattern includes a control to apply a voltage to at least one of segments of the plurality of segments which are not commonly used in the first segment group in a period from a predetermined time before starting of change to the third turning-on pattern.

Abstract: For providing a display device and a method for transferring an image data, shortening process time required to transfer image data without greater processing capacity, the CPU 4 outputs the bypass write signal to the GDC 6, the CPU 4 then outputs the read signal to both the ROM 5 and the GDC 6, and the ROM 5 outputs the image data to the data bus 8 according to input of the read signal, wherein the GDC 6 directly reads the image data outputted on the data bus 8 according to input of the read not through the CPU 4 and writes the read image data to the VRAM 7.

Abstract: A liquid crystal display device includes a display part which has a plurality of divided segments and a control part, configured to control voltages applied to the segments to turn on or turn off each of the segments. The control part changes a turning-on pattern of segments to be output to the display part from a first turning-on pattern which turns on a first segment group selected from the plurality of segments to a second turning-on pattern which turns on a second group selected from the plurality of segments. Change of the turning-on pattern includes a control to apply a voltage to at least one of the segments of the first segment group which are not commonly used in the second segment group in a predetermined time from starting of the change.

Abstract: A display device for a vehicle is provided, by which a driver of the vehicle is free from a trouble of adjusting a display position of the virtual image without cost-up of the device. When the support start detecting means detects a support start timing of adjusting a reflection angle, for example, a timing of an operation of an operation switch or a start of an operation, the rotation control means controls the rotating means so that the reflecting member having a reflection angle indicated by the reflection angle data stored in the reflection angle data storing means is (a) rotated within an adjustment supporting range on a condition that the reflecting member is reflecting the display light from the display source and (b) returned to a reflection angle indicated by the reflection angle data.
