Shenzhen Yousee Technology Co., Ltd Product Specification Version History

Shenzhen Yousee Technology Co., Ltd Product Specification

Shenzhen Yousee Technology Co., Ltd Product Specification 2.1 Product Applications Laptop/Notebook 3) Pixel arrangement: Real RGB arrangement

Shenzhen Yousee Technology Co., Ltd Product Specification Note(1): VDD_3.3V=3.3 (V) ELVDD/ELVSS =4.6/-2.4 (V), Full White pattern, Temperature = 22 + 3°C

Shenzhen Yousee Technology Co., Ltd Product Specification Room Temperature 7. Electro-Optical Specification Test condition: 25°C + 3°C, 65 + 20%RH, Dark room.

Shenzhen Yousee Technology Co., Ltd Product Specification Note 1: Brightness follows MicroSoft brightness3 (Based on OPR 50%). The Brightness of full white pattern (OPR100%) is the same as that of OPR 50%. Note 2: Brightness uniformity For brightness uniformity measureYousee EDO’s request as below: 1. The test condition is at 25ć and measured on the surface of Display panel module. 2. Measurement equipment: CS2000 or similar equipment. 3. The brightness uniformity is calculated by using following formula: Brightness Uniformity = Bp (Min.) / Bp (Max.)×100 (%) Bp (Max.) = Maximum brightness in...

Shenzhen Yousee Technology Co., Ltd Product Specification Note 3: 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 4: Color Gamut For brightness uniformity measure, EDO’s request as below: 1. Measurement equipment: CS2000A or similar equipment. 3. The color gamut is calculated by using following formula: Color Gamut % = S coverage / S original color gamut S coverage: The area covered by panel color gamut S original color gamut: The triangle area of DCI-P3 color gamut For gamma curve control, EDO’s request as...

Shenzhen Yousee Technology Co., Ltd Product Specification Note8: Color Shift For color shift measure: Fix on white pattern, On the condition θ=0 F=0°, we can get the color coordinate (u1', v1') and on θ=45° F=45° we can get another color coordinate (u2', v2') Delta = Square Root( (u2'-u1')^2 + (v2'-v1')^2 ) JNCD stands for "Just Noticeable Color Difference" For the (u', v') color space 1 JNCD=0.0040 4.5 JNCD means Delta u’v’<0.0180. This Requirement is from our customer and we have test some of our phone display and the result is Note9: Image Sticking The test condition is at 25ć and measured...

Shenzhen Yousee Technology Co., Ltd Product Specification 5. If the intensity level of the display changes as Fig 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 is defined as the flicker amount. 6. AC component (a) is defined as Vmax – Vmin and DC component (b) as (Vmax + Vmin)/2,and the flicker amount is calculated by the following formula. Flicker amount = AC component / DC component=b/a = (Vmax - Vmin)/{(Vmax + vmin)/2}×100% Flicker amount = AC component / DC component=b/a = (Vmax - Vmin)/{(Vmax...

Shenzhen Yousee Technology Co., Ltd Product Specification 5. Then use the max value between Crosstalk(V) and Crosstalk(H) as the final crosstalk. Note12: OLED Life Time The test procedure is as follows: At room temperature(25ć), light the module with typical value brightness(Full white). After that, record the brightness of center point every 24 hours. Then test 480h hours or more to collect the raw data. Finally, use the raw data and the specific formulas to calculate and estimate the T50. Note13: Retention z Test samples 5pcs; z Light on a 127 gray pattern

Shenzhen Yousee Technology Co., Ltd Product Specification 127 Gray pattern • Change to a Black &White pattern, and light on this pattern for 10 min; Black &White pattern • Then change the pattern back to 127 gray; • Capture the useful luminance data as below pattern: Useful data area • 1) Display the 127 gray scale pattern in full screen, measure the brightness, and calculate the X value.

Shenzhen Yousee Technology Co., Ltd Product Specification • 2) Switch to the black and white pattern and keep it for 10min. • 3) Switch to the 127 gray scale pattern. Use the CCD to measure the luminance of the red frame. The exposure time of the CCD is 0.3s. The test is performed 3600 times at an interval of 1s. The captured luminance values are as follows:
