Patent ID: 7774152

Claim:
A method of manufacturing an image display apparatus including at least one first wiring, a plurality of image display devices connected to the first wiring, and a plurality of second wirings connected to the plurality of image display devices, comprising the steps of: determining a signal applied to the second wirings; and applying a voltage to portions connected to the first wiring and the second wirings by application of a potential D L to a first predetermined position of the first wiring, application of a potential D R to a second predetermined position thereof, and application of the signal to the plurality of second wirings, wherein the determining step includes a step of setting a set value V j associated with a j-th position of a plurality of n positions, where j and n each are a positive integer, located between the first predetermined position and the second predetermined position on the first wiring, wherein in the setting step, the set value V j is set by the following expression V j = D L ⁢ a j + D R ⁢ b j - ∑ k = 1 n ⁢ c j , k ⁢ I k where I k denotes a current quantity flowing from a k-th position of the n positions, wherein when a resistance between the j-th position and a (j+1)-th position on the first wiring is R j , a resistance between a first position and one of the first predetermined position and the second predetermined position which is closer to the first position is R 0 , a resistance between an n-th position and one of the first predetermined position and the second predetermined position which is closer to the n-th position is R n , and a resistance between the first predetermined position and the second predetermined position is R all , a j , b j , and c j,k are expressed by a j = 1 R all ⁢ ∑ q = j n ⁢ R q b j = 1 R all ⁢ ∑ p = 0 j - 1 ⁢ R p c j , k = 1 R all ⁢ ∑ p = 0 min ⁡ ( j , k ) - 1 ⁢ R p ⁢ ∑ q = max ⁡ ( j , k ) n ⁢ R q wherein the setting step includes a step of setting the current quantity I k based on a result obtained by measurement of currents flowing through the second wirings, and wherein the determining step includes a step of determining the signal applied to the second wirings based on the set value V j .
