TAILOR PIXELS TECHNOLOGY CO., LTD. 6 Electro-Optical Specification Item Brightness Uniformity Contrast Ratio Remark Suggest MDL Brightness Note 1 Based on

lailorpixels TAILOR PIXELS TECHNOLOGY CO., LTD. Note 1: Brightness Uniformity • Environmental conditions: Temp. 25°C±3°C, 65±20%RH, Dark Room. • Measurement equipment: CS2000 or similar equipment. • The brightness uniformity is calculated by using following formula: Brightness uniformity = Bri.(Min.) / Bri.(Max.) x 100% Bri.(Min.) = Minimum brightness measured in 9 measuring spots.

TAILOR PIXELS TECHNOLOGY CO., LTD. Bri.(Max.) = Maximum brightness measured in 9 measuring spots.  Illustration of 9 measuring spots as follows Note 2: Contrast Ratio Dark Room C.R=LW/LB LW: Full white brightness of display center P0; LB : Full black brightness of display center P0. Note 3: Viewing Angle Refer to the figure below marked by θ and ϕ

TAILOR PIXELS TECHNOLOGY CO., LTD. Note 4: Color Shift JNCD  For JNCD measure, fix on white pattern, on the condition θ = 0°, ϕ= 0°, a color coordinate (u’1, v’1) can be obtained and another color coordinate (u’2, v’2) can be obtained on θL=30°. Delta u’v’ = square root ((u’2-u’1)^2+(v’2-v’1)^2), and JNCD stands for “Just Noticeable Color Difference”. For the (u’, v’) color space 1 JNCD = 0.004 Delta u’v’, For example, color shift less than 2 JNCD means Delta u’v’ < 0.008. Measurement equipment: CA-210 or similar equipment. Measuring temperat

TAILOR PIXELS TECHNOLOGY CO., LTD. • Test pattern: Refer to below (Test pattern should be full-fill of display screen). • The point should be marked is, the background of Flicker test pattern -'gray" is defined as middle gray scale. For example, RGB 24 bit 'gray' is defined as below: • Frame frequency requirement before test: The display panel must be tuned to more than 60 Hz before measurement. • If the intensity level of the display changes as Figure below, it is considered that AC component (b) overlaps on the DC component (a). With the contrast method, the ratio of AC component to DC component...

lailorpixels TAILOR PIXELS TECHNOLOGY CO., LTD. Note 6: Crosstalk • Measurement equipment: CS2000 or similar equipment. • The background of crosstalk test pattern 'gray' is defined as middle gray scale. For example, RGB 24 bit 'gray' is defined as below' • Test pattern follows the picture below, the background is middle gray and with two black rectangle parts, each one is 1/9 of the AA size. • Calculate the crosstalk (V) and crosstalk (H) with the formula below:

lailorpixels TAILOR PIXELS TECHNOLOGY CO., LTD. Note 7: Polarization Direction Definition • Viewing direction is normal user viewing direction which is vertical to the display surface. • The X axis is defined as parallel to Top and Bottom sidelines of the Active Area. • PdF which is marked in blue arrow in the figure below is polarization degree. • The polarization degree parameter is indicated in range of 0 deg. to 180 deg. according to above definition.

lailorpixels TAILOR PIXELS TECHNOLOGY CO., LTD. Top sideline of Active Area Bottom sideline of Active Area Note 8: Definition of Response Time The output signals of photo detector are measured when the input signals are changed from 'black' to 'white' (voltage falling time) and from 'white' to 'black' (voltage rising time), respectively. The response time is defined as the time interval between 10% and 90% of the amplitudes, as shown in the figure below:

lailorpixels TAILOR PIXELS TECHNOLOGY CO., LTD. • Response time of gray to gray Measurement equipment: CS2000 or similar equipment. Test method: 8 grays L0 to L7 are defined, the gray level of which are 0, 36, 73,109,146,182, 219, and 255. The output signals of photo detector are measured when the input signals are changed from 'Lx' to "Ly", [x, y] = [0, 7]. The response time is defined as the time interval between 10% and 90% of the amplitudes. The result of the test can be noted as below:

TAILOR PIXELS TECHNOLOGY CO., LTD. Note 10:Class C will be executed unless otherwise specified :

TAILOR PIXELS TECHNOLOGY CO., LTD. 8 Handling Precautions 1) When cleaning ITO pad, avoid using hard and abrasive material or corrosive solution 2) Keep module away from direct sunlight or fluorescent light, and keep it at room temperature and humidity 3) Strong impact & pressure on module and packing is prohibited 4) Following normal power on/off sequence is necessary for preventing abnormal display or permanent damage to display 5) Optimal contrast ratio under ideal voltage is AMOLED module’s characteristic, hence it is recommended a voltage control function available. 6) Image sticking may...
