With the image display device, sampling of video signals is surely executed without increasing the number of shift registers. It is thus possible to reduce the size and weight of the image display device and to decrease the defect rate thereof. Moreover, the scanning circuit achieves a higher yield compared with a conventional scanning circuit using a shift register.

摘要： A scanning circuit is provided with a plurality of address lines and AND circuits. The address lines respectively supply bit signals constituting an address signal and inverted bit signals, and each AND circuit conducts a logical operation on a predetermined number of bit signals and inverted bit signals selected from the bit signals and inverted bit signals supplied from the address lines. The AND circuits are connected to the address lines so that only one bit is switched when the address signal carries. Furthermore, a frequency of the least significant bit of the address signal is set to 1/4 of the dot frequency, while the two bits at the high end are set to have the same frequency and a phase difference of 90.degree. each other. With the described arrangement, a phase shift is prevented from occurring to an outputted signal when the address signal carries. Furthermore, the arrangement ensures that the scanning circuit can be realized in a simple circuit arrangement and operates at low frequencies, thereby ensuring a decrease in power consumption.

摘要： A delay detecting section detects the phase difference between a first detection signal as a reference and a second detection signal produced by delaying the first detection signal with part of a data signal line driving circuit itself or part of a circuit formed by the same process as the data signal line driving circuit. A phase adjusting section presumes an internal delay of the data signal line driving circuit, and adjusts the phase difference between a clock signal and start signal, and a video signal so that the data signal line driving circuit samples the video signal at an appropriate timing. These structures prevent a lowering of the image quality due to a difference in the timings of the video signal and sampling signal, and provide an image display device capable of displaying a good-quality image with a simple circuit structure.

摘要： In order to sufficiently save the power consumption and to lower the withstand voltage of elements, by having one data signal line per one row of pixels and one scanning signal line per one line of pixels, the polarity of data written in the data signal line is varied each one field period. The power source magnitude of the scanning signal lines to be written is further varied each one field period. Specifically, on opposing sides of the pixel array, data signal line driving circuits are provided. The data signal line driving circuits supply voltages of different magnitude and polarity. Adjoining pairs of data signal lines are connected to each of the data signal line driving circuits with analog switches. In a certain display period, such as every field period, the analog switches each select one of a pair of adjacent data signal lines. In the next display period, the reverse selection is made. This suppresses the charge and discharge current of the data signal lines, and thus the operating voltages of the data signal line driving circuits may be lowered. As a result, the power consumption of the image display device may be saved, and the withstand voltage of the constituent elements can be lowered. Thus, manufacturing cost and operating cost can be reduced.
