4.3

Calculate Linearity : For the First Row0

R0avg = ( VC0 + VC1 + VC2 +- - - - - - - + VC9)

÷ 10

R0max = The maximum voltage in Row 0

R0min = The minimum voltage in Row 0

R0 linear1 =

⏐ R0 max – R0 avg. ⏐ ÷ R0 avg. ∗ 100%

R0 linear2 =

⏐ R0 min – R0 avg. ⏐ ÷ R0 avg. ∗ 100%

R0 linear = max (R0 linear1, R0 linear2)

4.4

For X Coordinate Test

Add 5 voltage between X1 and X2 touch the point C0R0 to C9R9 separately and measure the voltage from Y1

as the above drawing

4.5

Calculate Linearity : For the First Column0

C0avg = ( VR0 + VR1 + VR2 +- - - - - - - + VR9 )

÷ 10

C0max = The maximum voltage in Column 0

C0min = The minimum voltage in Column 0

C0 linear1 =

⏐ C0 max – C0 avg. ⏐ ÷ C0 avg. ∗ 100%

C0 linear2 =

⏐ C0 min – C0 avg. ⏐ ÷ C0 avg. ∗ 100%

C0 linear = max ( C0 linear1 ,C0 linear2 )
