Title: Humidity sensible element
Inventor: SAKAI YOSHIRO
IPC: G01N27/22
Filed: 1987-07-15
Abstract: PURPOSE:To decrease a drift in a state that it is contrived to secure the sensitivity as a humidity sensible element, by forming a humidity sensible film by using a high polymer consisting essentially of ethyl cellulose. CONSTITUTION:A humidity sensible film 3 is formed by a humidity sensible material consisting essentially of ethyl cellulose EC especially, in a cellulose ether high polymer. The humidity sensible film 3 has the quality whose dielectric constant becomes large, although its adsorption moisture quantity is small, since the main component is EC. That is, as far as the EC is concerned, its adsorption site is much smaller or its hydrophilic property is weaker than an organic high polymer such as CAB, CAP, PAI, etc. The adsorption moisture quantity of the EC is a value which can secure enough the hydrophilic property being suitable for using it as a humidity sensible element of a capacity type, and also, since its adsorption moisture quantity is small, a more stable (drift is small) humidity sensible characteristic than a sensor on the market, using the CAB can be obtained with small hysteresis and with high response.

Abstract: PROBLEM TO BE SOLVED: To improve the galvanic corrosion resistance of a terminal on a transparent insulated substrate by arranging/forming the terminal so as to decrease a DC potential difference between the terminals in order to lower the intensity of DC electric field between the terminals. SOLUTION: Input terminals Tg0-Tg15 provided on a transparent insulated substrate SUB1 and connected to the bumps of driving ICs for gate scanning are arranged/formed so that the intensity of DC electric field between terminals Tg is decreased i.e., the potential difference between terminals Tg is decreased. For example, a potential difference between Tg1 and Tg2 is 22V, a potential difference between Tg3 and Tg4 is 19V, a potential difference between Tg8 and Tg9 is 5V, a potential difference between Tg9 and Tg10 is 5V, a potential difference between Tg11 and Tg12 is 19V and the DC potential differences are large. An interval between terminals is made wide. Consequently, since the intensity of DC electric field between the terminals Tg is reduced, galvanic corrosion is hardly generated and galvanic corrosion resistance is improved.
