摘要： A liquid crystal display device (1) according to the invention, when an image corresponding to an inputted video signal is a moving image complying with an interlace system, inserts a black signal as an interpolation signal into each of corresponding interlace non-scanning portions (101) without generating the interpolation signal from upper and lower side scanning lines with respect to a scanning line concerned for the video signal (100a or 100b). Alternatively, the interpolation signal generated from the upper and lower side scanning lines with respect to a scanning line concerned for the video signal can also be inserted into each of corresponding interlace non-scanning portions (101) instead of using the black signal.

摘要： A control apparatus for an active matrix liquid crystal display device is fabricated with the active matrix as a single integrated SOI circuit. The control apparatus and the active matrix are lifted from a silicon substrate and transferred to a glass substrate as a single piece. The control apparatus comprises a video interface, a column driver, and dual row drivers. The video interface operates the active matrix as a multiple-frequency scanning display device. The column driver comprises dual shift register arrays, one array coupled to the even columns and the other array coupled to the odd columns. The even and odd columns operate at opposite polarities. The respective polarities are reversed on every frame by a polarity switch the polarity switch coupled to a video signal amplifier. The control apparatus further comprises sensors for generating a gray-scale feedback signal to adjust the amplifier gain. The sensors comprise a temperature sensor within the active matrix and a light sensor measuring light transmission through the liquid crystal material.

摘要： A matrix of display elements is driven on a time sharing basis to switch between two optically distinct states in response to a pulse train applied to the selected display elements. The pulse train includes display control pulses having a duration and electric field effective to set the display elements to the desired optically distinct state, and does not allow, after the application of the display control pulse, existence of a pulse which would change the optical state, and also includes a plurality of pulses having the same pulse shapes in different polarities. AC pulses which hold the optical state are applied to the display elements after the application of the display control pulse. The AC pulses are obtained by superposing high frequency AC pulses to the AC pulses having an amplitude lower than the display control pulse.

摘要： An insulated-gate field-effect transistor adapted to be used in an active-matrix liquid-crystal display. The channel length, or the distance between the source region and the drain region, is made larger than the length of the gate electrode taken in the longitudinal direction of the channel. Offset regions are formed in the channel region on the sides of the source and drain regions. No or very weak electric field is applied to these offset regions from the gate electrode.
