1.2 About 42V5 model

X means XGA resolution (1024Ⅹ768) .

using dual scan method

V5 shows 1000:1 contrast ratio and 1000cd.

So V5 called as KK model.

1. We want to communicate harmoniously by educating a defect phenomenons and terms

to send LG Electronics a message that includes a detail articles of defect panel.

2. Let customers can distinguish module defect(LG Electronics defect) and a defect from their work by

educating an early analysis for SET maker .So customers can decide easily whether it is LG defect or customer’s.

3. Prevent defects which is made during set assembly process previously by educating

Work precautions and conditions.
