Title: Driving method for liquid crystal device
Inventor: MASE AKIRA
IPC: G09G3/36
Filed: 1990-08-02
Abstract: PURPOSE:To obtain the display device which has good display performance by regarding up to seven-times writing operation on the liquid crystal device as one cycle, constituting a gradational display digitally, and performing rewriting operation >=210 times in one second. CONSTITUTION:A liquid crystal composition which is ferroelectric is ferroelectric liquid crystal which has a fast response speed, so rewriting can be performed >=210 times in one second. A liquid crystal controller 18 receives a 16-bit image signal sent from a computer 19 and performs ON-OFF control to generate a gradation signal. For example, a gradation level 7 enables light to be transmitted four times in seven-times rewriting and the mean light transmissivity is 57.1%. Thus, the gradation level is set according to the difference in frequency between transmission and nontransmission. The dot constitution of a liquid crystal panel 13 which uses the ferroelectric liquid crystal composition is set to specific quantities. The screen is divided into an upper and a lower part at the center and they are driven with a specific time-division number value. Consequently, the liquid crystal display device which can easily make a gradational display is obtained.

Abstract: PURPOSE:To flatten the surface and thermal conductivity of a substrate by varying the grain size of the polycrystal of different type of material from that of the substrate deposited on a ceramic substrate in the thickness direction of the substrate, and forming two or more polycrystalline layers. CONSTITUTION:The polycrystal of a lowermost layer 1 formed on a ceramic substrate 1 has small grain size of 0.5mum or less, and voids of the surface of the ceramic substrate are buried and the distortion due to the difference of linear expansion coefficients of different types of materials are alleviated. A second layer 3 has grain size or 2mum or more with less grain boundaries to hold high thermal conductivity. A third layer 4 has small grain size of 0.5mum to improve the flatness of the substrate surface. Thus, since a hybrid substrate varies the grain sizes of the polycrystal in the direction of the thickness of film, its surface is flat and its thermal conductivity is improved.
