The definition of Vth & Vsat 6 2.Viewing angle is the angle at which the contrast ratio is greater than 10. The viewing are determined for the horizontal or 3, 9 o’clock direction and the vertical or 6, 12 o’clock direction with respect to the optical axis which is normal to the LCD surface. Figure 3.Definition of viewing angle 3. Contrast measurements shall be made at viewing angle of Ө= 0° and at the center of the LCD surface. Luminance shall be measured with all pixels in the view field set first to white, then to the dark (black) state.

The color chromaticity coordinates specified in Table 6. shall be calculated from the spectral data measured with all pixels first in red, green, blue and white. Measurements shall be made at the center of the C/F. Measurement condition is C - light source & Halogen Lamp. Figure 4 Optical test equipment. 6. The electro-optical response time measurements shall be made as FIGURE 3 shown in Appendix by switching the “data” input signal ON and OFF. The times needed for the luminance to change from 10% to 90% is Tr, and 90% to 10% is Td Figure 5.Definition of response time: Tr+Tf PG1302XA-NA0 -8- 7 INTERFACE PIN CONNECTIONS PIN NO. 1 2 3 4 5 6 7 8 9 10 11 12 SYMBOL GND LEDA LEDK VDD GND TE D/C CS SCL SDA RESET GND FUNCTION DESCRIPTIONS System ground.

This standard for Quality Assurance should affirm the quality of LCD products to supply to purchaser by PGO. Entire process is controlled according to ISO9000 in factory. 9.2 Standard for quality test (1) Inspection Before delivering, the supplier should take the following tests, and affirm the quality of product. (2) Electro-Optical Characteristics According to the individual specification to test the product. (3) Test of Appearance Characteristics: According to the individual specification to test the product. (4)Test of Reliability Characteristics According to the definition of reliability on specification for test product. (5) Delivery Test Before delivering, the supplier should take the delivery test (6)Sampling Method: GB/T2828.1-2003, Level II (7) The defects classify of AQL as following Major defect: AQL=0.65 Minor defect: AQL=1.5 9.3 Nonconforming Analysis & Deal With Manners ☆Nonconforming Analysis (1) Purchaser should supply the detail data of nonconforming sample and the non-suitable state. (2) After accepting the detail data from purchaser ,the analysis of nonconforming should be finished in two weeks. (3) If supplier can not finish analysis on time ,must announce purchaser before two weeks. ☆Disposition of nonconforming (1) If find any supplier defect during assembly line, supplier must change the good product for every defect after recognition. (2) Both supplier and customer should analysis the reason and discuss the disposition of nonconforming when the reason of nonconforming is not sure. 9.4 Agreement items. PG1302XA-NA0 -11- Both sides should discuss together when the following problems happen: (1) There is any problem of standard of quality assurance ,and both sides think that must be modifier. (2) There is any argument item which does not record in the quality assurance. (3) Any other special problem. 9.5 Standard of the Product Appearance Test 9.5.1 Manner of appearance test (1) The test must be under 20W*2 or 40W fluorescent light ,and the distance of view must be at 30±5 cm. (2) When test the model of Transmissive product must add the reflective plate. (3) Definition of Area: A Area: Active area B Area: Viewing area C Area: Out of viewing area D Area: Seal area C Area B Area A Area D Area Figure7 9.5.2 Basic principle: (1) It will accord to the AQL when the standard can not be described. (2) The sample of the lowest acceptable quality level must be discussed by both supplier and customer when any dispute happened. PG1302XA-NA0 -12- (3) Must add new item on time when it is necessary. 9.6 Inspection specification NO 01 Item Electrical Testing PG1302XA-NA0 Criterion 1.1 Missing vertical, horizontal segment, segment contrast defect. 1.2 Missing character, dot or icon. 1.3 Display malfunction. 1.4 No function or no display. 1.5 Current consumption exceeds product specifications. 1.6 LCD viewing angle defect. 1.7 Contrast defect -13- AQL 0.65 2.1Round type: As following drawing φ=(x+y)/2 X Y Acceptable QTY Size LCD black spots, white spots, color 02 A.A Ignore φ≦0.10 0.10
