<p>PURPOSE:To bring all of the resistance values of two resistor elements forming a picture element to the same value by fixing the resistance values of separate resistor element held by alternately led-out electrodes by applying pulse-shaped voltage and connecting ones of the electrodes. CONSTITUTION:An electrode pattern is shaped, a resistor film 6 is formed onto alternately led-out electrodes through printing and baking, and a protective film mainly comprising SiO2.PbO is shaped through printing and baking. The resistance value of a resistor element 6 held by the electrode 1a and the electrode 2a is measured, the rate of change of the resistance value for changing the resistance value into an aimed resistance value is computed, and corresponding applied pulse voltage is acquired. When pulses having the voltage are applied between the electrode 1a and the electrode 2a, the resistance value of the resistor element 6a is turned into the target value. The resistance value of the next resistor element 6b held by the electrode 1a and the electrode 2a is adjusted, thus trimming the resistance values of all resistor elements at the target value.</p> |
