摘要:
A liquid crystal halftone display system including a tone generator which, for pixels having P tones of K tones (1≦P≦K), alternately outputs first N-bit tone display data and second N-bit tone display data in successive frames at one of a first phase and a second phase. Within a block of pixels, the tone generator alternately inverts the phase of the N-bit tone display data at successive first pixels having different ones of the P tones within the block of pixels beginning at a left side of the block of pixels, and alternately inverts the phase of the N-bit tone display data at successive pixels having a same one of the P tones within the block of pixels beginning at the left side of the block of pixels.

摘要:
A liquid crystal active matrix display device includes a first substrate having a thin film transistor formed thereon. A light-screening film 1 is located on the first substrate in a manner to be overlapped with an ITO. The display device includes a second substrate having a color filter and a light-screening film 2 formed thereon. The second substrate is opposed to the first substrate. The light-screening film 2 extends from the uncontrollable area by a certain value depending on a voltage from the external, resulting in improving a numerical aperture.
摘要:
A photoresist 10 is exposed to light from behind a substrate by using as photomask a wiring electrodes 2 and 4 and a switching element 8 which are individually composed of an opaque member, whereby a passivation layer 9 for the switching element 8 is patterned. By virtue of this method, a photomask becomes unnecessary and jogs of the passivation layer 9 can be formed outside the transparent pixel electrode 7. Therefore, an unsatisfactory orientation of a liquid crystal can be made invisible without enlarging the black matrix of a counter substrate. Furthermore, since a passivation layer can be removed in portions not requiring the passivation layer, image-sticking can be reduced and the quality of displayed picture can be greatly improved. The present invention makes it possible to reduce the number of photomasks used for production of an actively addressing substrate and improve the picture quality of a liquid crystal display.

A liquid crystal display device and a manufacturing method therefor are provided where the number of processes for manufacturing TFT substrates can be decreased and a high production yield can be attained. To attain these objects, an image signal bus-line includes at least a transparent conductive film and a semiconductor layer. A pattern of the transparent conductive film extends up to a thin film transistor to form its drain electrode, and a pattern of a semiconductor layer extends up to the transistor to form its source electrode. By virtue of these arrangements, the thin film transistor substrate can be manufactured using as little as three or four photolithography processes.

摘要:
A display system has signal lines and scanning lines arranged in a matrix with the signal lines extending generally perpendicular to the scanning lines. At each intersection of the signal and scanning lines is a display unit, each such unit having a display element such as a liquid crystal display element, a switching means between the display element and the signal line, and a current limiting means between the switching element and the scanning line. By applying suitable signals to the signal and scanning lines, from suitable signal and scanning controllers, each display unit may be addressed. In order to prevent defects due to a short circuit across the switching element between the current limiting means and the signal line, signals are applied to the signal lines at times other than when signals are applied to the scanning lines. Therefore, a suitable voltage can be applied to any defective display unit so as to cause the display element to be controlled so that it is in the desired state. Thus, if the display elements are liquid crystals, they may be controlled so as to be dark if they are faulty.

摘要:
A matrix panel display apparatus includes plural signal lines and plural scanning lines intersecting each other and, near each intersection point, a picture element including a picture element electrode, a counter electrode, a display medium disposed between the picture element electrode and the counter electrode, and a transistor for applying image signals from the signal line to the picture element electrode. The transistor is controlled in response to scanning signals received on a scanning line. An auxiliary signal generating circuit generates auxiliary signals for increasing effective voltages of the image signals and applies the auxiliary signals to the picture elements while each of the transistors is in a non-conducting state and each of the picture elements is not selected. Preferably, the auxiliary signal generating circuit applies the auxiliary signals to the picture elements during a predetermined period in which all of the transistors are in the non-conducting state and none of the picture elements is selected.
