4 Picture Quality Factors Brightness Contrast Color Sharpness Viewing Angle Response Time Uniformity Jaggy Jerky

5 A Typical Picture Specification Screen Size : 30" (76 cm) Visible Screen Size : 75 cm (29,53) Display : LCD WXGA Active Matrix TFT technology Resolution 1280x768 (x3) pixels Response time LCD : 16 ms Brightness : 450 cd/m 2 Contrast Ratio : 350:1 Viewing Angles : 176H/176V Anti Reflex Coated Screen

6 Brightness More backlight

7 Contrast Whiter and blacker

8 Gamma Correction The detail of black and white field

9 Color - cross color Cross-color

10 Color – flesh tone correction Too healthy

11 Color – white balance & color temperature Black Body Locus 5300K 6500K 9300K

12 Color Temperature Normal Warm Cool

13 Sharpness More clear edge

14 Viewing Angle Good Bad Lower contrast, color

15 Response Time Tailing

16 Uniformity Mura
