摘要： A driving system of the present invention for use in a displaying device is provided with a pseudo bit-depth extension section. In the pseudo bit-depth extension section, a noise pattern is added to upper-n-bit data of an input signal D0 in m-bit, where (i) m is an integer of 9 or greater, and (ii) n is an integer of 8 or greater, but less than m. Then, upper-n-bit of data D1 thus obtained from the D0 is outputted, as output data D2, from the pseudo bit-depth extension section. The driving system is further provided with an overshoot-driving section for carrying out an overshoot-driving with respect to each of pixels. A noise amount of the noise pattern is 1 or less in 8-bit data, and a calculation in the overshoot-driving section is carried out with n-bit data. With this driving system which adopts a combination of (a) a overshoot-driving method for enforcing liquid crystal to respond at a high speed, and (b) a bit-depth extension technology in which a number of grayscales is increased by adding noise, it is possible to provide, at a low cost, a high-definition displaying device such as a liquid crystal display, having a high-response-characteristics and a high quality of grayscale reproduction.

摘要： In the first display mode, a first tone converting circuit and a second tone converting circuit of a control LSI divide one frame period of an input image signal into a plurality of sub-frame periods to perform output to a display panel, thus realizing image display performed by time-division driving (pseudo-impulse driving). In the second display mode, the control LSI directly outputs an input image signal to the display panel, thus realizing image display performed by hold driving. In at least one embodiment, switching between the first display mode and the second display mode is performed by changing output of an output data selector according to a mode switching signal. This realizes an image display apparatus which effectively obtains the effect of suppressing blurring of a moving image and alleviates the problem of flickers caused by pseudo-impulse driving.

摘要： An image display device displays an identical image based on display data output from a display control circuit on its own display panel and an external display unit connected to the device through an interface. The device can erase and freeze an image on the external display unit in an erase mode and a freeze mode, respectively, while the display panel displays different images. In order to do so, this device has a frame memory circuit for storing and outputting display data received from the display control circuit toward the external display unit and a disable circuit for stopping data received from the frame memory circuit from being output and instead outputting monochromatic or single-color data to the external display unit. The frame memory circuit inhibits data stored in its memory from being rewritten during the freeze mode. The disable circuit outputs the monochromatic data in the erase mode. During the freeze mode and the erase mode, the display panel can display a freeze sign and an erase sign, respectively, along with an image, by means of a sign pattern generator and a synthesize circuit. The sign pattern generator, the synthesize circuit, the frame memory circuit and the disable circuit are controlled by a control circuit which is also controlled by a CPU.

摘要： Plural controller circuits capable of mutually exchanging data are used as a display controller, the plural controller circuits connected to each other via a data bus. Each of the controller circuits, which receives image data, (i) transfers image data other than image data of a screen region, driving of which the controller circuit is in charge of controlling, on the other hand, (ii) stores, into a line memory section thereof, the image data of the screen region, driving of which the controller circuit is in charge of controlling together with image data that is transferred from another controller and that is for the screen region, driving of which the controller circuit is in charge of controlling, and converts the thus stored image data into output image data. This makes it possible to establish common use of a display controller for different resolutions so as to provide cost merit.

摘要： A display device includes a left and a right panel sections provided adjacently along a sequence of a plurality of data signal lines, and a plurality of source drivers which are provided along a sequence of the data signal lines and correspond to the panel sections. A controller sends data signals to the respective source drivers in parallel, and a start signal to one of the source drivers in each of the display panel. In each panel section, an operation of acquiring data signals sequentially shifts from the source driver having received the start signal to the next source driver. The controller sends the start signals to the two source drivers closest to a border between the two display regions, and rearranges an order of data signals, which are supplied to source drivers in one of the display regions, to be in line with an order of data signals which are supplied to the other one of the display regions.
