DEM 16227 SYH-LY Product Specification
VERSION: 2 PAGE: 13
5.2 The LCM shall be tested at the angle of 45° both left side and right side, and 0-45° both top
side and bottom side (for STN LCM, at 20°~55°):
5.3 Definition of VA
A area：Display area（AA area）
B area: Viewing area（VA area）
C area: Non-viewing area（not viewing after customer assembly）
If there is any appearance viewing defect which do not affect product quality and customer
assembly in C area, it’s accepted generally.
The criteria apply to A and B area except chipping and crack.
5.4 Inspection with naked eyes（exclusive of the inspection of the physical dimensions of
defects carried out with magnifiers）.
5.5 Electrical properties: Inspection with the self-made/special LCM test jigs against the product
documents or drawings; display contents and parameters shall conform to their
documents requirements and the display effect to the drawing.
5.5.1 Test voltage（V）：(Determined) according to the operating instruction of test jigs
assuming the external circuit can be adjusted unless the customer otherwise specifies
driving voltage(s). (Display) effects are controlled within the specified range of voltage
variation (If no specific requirements, display effects are controlled at Vop = 9V or Vop
±0.3V when Vop is below 9V; if Vop is above 9V, display effects are controlled at Vop ±
3% at least).For display products with the customer-specified fixed Vop, display effects
are controlled by adjusting the internal circuit; if necessary, acceptable limit samples
shall be built.
5.5.2 Current Consumption（I）：Refer to approved product specifications or drawings.
5.5.3 Size: for the outline dimension and the position which maybe affect customer assembled
all should conform to the technical drawing requirements.
