Sharp Electronics 

NOTES :

1. VCOMRSDS = (V**P+V**N)/2 = 1.2 V

**P = X0P-X2P, Y0P-Y2P, Z0P-Z2P

**N = X0N-X2N, Y0N-Y2N, Z0N-Z2N

2. VDIFFRSDS = V**P – V**N = 0.2 V

3. Criterion of evaluating voltage deviations.

(a) Between output voltage pins

Measuring values : Output voltage value at the time after

10 µs at the rising edge of LS.

(Average of several times)

(Conditions) Output load capacity is 150 pF.

In a state when the reference voltage is fixed.

Expecting values : Calculated following these specifications.

(Conditions) In a state when the reference voltage is fixed.

(b) Between LCD drivers.

Measuring values : Applicable to (a).

(Conditions) Applicable to (a).

Expecting values : Applicable to (a).

(Conditions) Applicable to (a).

Each input voltage between the LCD drivers must be

made perfectly equal by connecting corresponding

reference voltage input pins.
