Shenzhen Yousee Technology Co., Ltd 接触放电 空气放电 Product Specification TP处于工作模式时进行测试， 测试后TP功能应正常 Power supply for OLED Power supply for OLED Power supply for OTP. Leave the pin to open when not in use. GND Driver IC analog supply

Product Specification Shenzhen Yousee Technology Co., Ltd 5.5 Recommended Operating Sequence 5.5.1 Power on sequence

Shenzhen Yousee Technology Co., Ltd Product Specification 5.5.3 Timing requirements for RESETB When RESETB of the reset pin equals to Low, it will be in the condition of reset. When it is in the condition of reset, it will make the device recover the initial set. However, in order to avoid the reset noise cause reset, there is a mechanism to judge about whether the reset is needed or not. The closed interval of Low can be shown as the following.

Shenzhen Yousee Technology Co., Ltd Product Specification Color Temp（与色坐标定义重复） 影像残留（Image Retention） 亮度衰减率 Luminance decrease ratio OLED Life Time

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. Fix on one pattern like white pattern, On the condition 0=0 0=0°, we can get the color coordinate (ul1, vl') and on 30° can get another color coordinate (u2', v2') Delta = Square Root( (u2' - u1')A2 + (v2' - v1')A2 ) JNCD stands for "Just Noticeable Color Difference" For color shift we need to measure white/red/green/blue pattern To check image retention, a 8x8 Chess Pattern shall be displayed for 30sec...

Shenzhen Yousee Technology Co., Ltd Product Specification Suggested Instruments: Konica Minolta CA-310 or Klein Instruments K-8 The flicker level is defined by Fast Fourier Transformation (FTT) as follows: Where fFFTC(n) is the n-th FFT coefficient. fFFTC(0) is the 0-th FFT coefficient which is DC component. FS(Hz) is the flicker sensitivity as a function of frequency. The peak flicker level shall be reported based on the calculation using above formula in which FS(Hz) is determined by the flicker weighing factor shown below. Crosstalk shall be calculated by the luminance of B1~B4 and G1~G4 in...

Shenzhen Yousee Technology Co., Ltd Product Specification OLED life time is defined by the Minimum Duration Time that the luminance is decayed to a specific ratio (ex. 95%) of initial state. Test Pattern under duration period: L255 White Environmental Test Main spec High Temperature Operation High Temperature Storage Low Temperature Storage High Temperature Humidity Operation Thermal Shock
