摘要： A glass substrate for supporting an electroluminescent (EL) display element comprising two dielectric layers defining a thin film EL layer, and two electrode layers, attached to each of the two dielectric layers is characterized by being composed of barosilicic acid without hydrolytic products thereon. A method for preparing such a glass substrate comprises the steps of preparing a glass substrate composed of borosilic acid, grinding a surface of the glass substrate, and cleaning the surface of the glass substrate without soaking it in an acidic solution, so that the glass substrate is free from formed hydrolytic products on the surface.

摘要： A thin film transistor comprises a substrate, a gate electrode, a drain electrode, a source electrode, an insulative layer, and a semiconductor layer for the purpose of switching display signals to be applied to at least one display element of a display device. Preferably, the thin film transistor is mounted on the same substrate on which the display element is mounted. The selected material for the display element electrode is identical to at least one selected from the gate electrode, the source electrode, and the drain electrode. In another aspect of the present invention neither the gate electrode nor the insulating layer overlap either of the drain electrode or the source electrode. A resistance value of the semiconductor layer between the source and the drain electrodes is considerably less than the resistance value of the semiconductor channel layer controlled by the gate electrode. For this purpose, at least one of the width, thickness, and impurity concentration is varied therebetween. In a further aspect, the semiconductor channel has a substantial length more than the distance between the source electrode and the drain electrode with the help of a labyrinth passage.

摘要： An additional electrode is provided for developing a secondary electrochromic phenomenon on a counter electrode apart from the major electrochromic phenomenon which is developed between one or more display electrodes and the counter electrode. Current flows from an additional electrode to the counter electrode in developing the secondary electrochromic phenomenon. Coloration of the counter electrode, where the magnitude of an overvoltage of the counter electrode is small is stabilized to thereby enhance electronic properties of the electrochromic display. The material of the additional electrode is selected from metals having an appropriate ionization tendency with respect to an electrolyte, such as Mg, Al, Zn, Cr, Fe, Ni, Sn, and Pb, or a combination thereof. Otherwise, the material of the additional electrode is selected to be an inert material with respect to the electrolyte such as Ag, Au, Pt, Pd, In.sub.2 O.sub.3, and SnO.sub.2 or a combination thereof. The combination which is composed of both the appropriate ionization tendency metals and the inert metals can be available for the additional electrode. The electrochromic display can be controlled under one of several groups of driving techniques consisting of a potentiostatic driving, a constant current driving, and a constant voltage driving method.

摘要： In accordance with the invention, gradation display is performed for each picture element in capacitive display apparatuses such as EL display apparatus by means of pulse width modulation. In doing so, pulse duration of the voltage applied to one group of electrodes among the a plurality of electrodes arranged in matrix is so set as to span over two scanning periods, during which another group of electrodes which are grouped into pairs each of two adjacent lines are scanned successively. This reduces the number of drive voltage charge and discharge cycles. Consequently power consumption of the display apparatus of PWM system can be controlled to a low level.
