Except for other provisions in this standard, the test should be carried out at the rated current. The test current should be stabilized within the range of ±0.5% of the rated current Inside, the total harmonic content input should not exceed 3%. Unless otherwise specified by the manufacturer, the test panel shall be installed horizontally or vertically during the test. The flexible OLED panel should be fixed to the table On a rigid flat plate with a flat surface, it is ensured that it does not deform during the entire test process. The installation method of the OLED panel during the test shall be recorded. 5.2 Stable The stabilization of the OLED panel should be carried out in a non-convection environment with an ambient temperature of 25℃±1℃ and 1 atmosphere. In the constant current mode, the OLED panel should be lit under specified conditions, and the input current should be stable within ±0.5%. In stability In the process, the actual voltage of the OLED panel is measured at an interval of at least 1 min/time. For example, within 5 minutes, the OLED panel voltage reading is the largest If the difference between the value and the minimum value is less than 0.5%, the OLED panel has reached a stable state and can be tested.6 Technical requirements6.1 Dimensions The external dimensions of the OLED panel should conform to the manufacturer's declared value, but the actual measured value should be within the tolerance range specified by the manufacturer. 6.2 Initial electrical performance The power of the OLED panel should conform to the manufacturer's declared value, and the actual measured value should not be greater than 110% of the declared value. 6.3 Initial optical performance 6.3.1 Luminous flux The luminous flux of the OLED panel should meet the manufacturer's declared value, and the actual measured value should not be less than 90% of the declared value. 6.3.2 Light effect The luminous efficiency of OLED panels is classified according to its power (P), which should not be less than the regulations in Table 2. b) When the OLED panel is lit for 6000h, its luminous flux maintenance rate should not be less than 75%.

The OLED panel should be lit under the specified conditions, and after stabilization, use a brightness meter to test the brightness of 9 points in the light-emitting area. Among them, rectangular OLEDAppendix A(Informative appendix) Luminous flux measurement method A.1 General There are two typical methods for measuring luminous flux. one is the spherical photometer method using an integrating sphere, and the other is the light distribution using a goniometer. Measurement methods. When using the integrating sphere measurement method, there are two methods. 2π method and 4π method. A.2 Integrating sphere measurement A.2.1 Installation location In the integrating sphere, the OLED panel should be placed in the center of the integrating sphere. This is to maintain the uniformity of the integrating sphere's illumination. On this side In the method, in addition to the light emitted from the surface, the light emitted from the side will also be measured, which satisfies the definition of luminous flux. A.2.2 Integrating sphere size In the 4π structure, the total surface area of the OLED panel should be less than 2% of the total area of the integrating sphere wall. The longest physical size of a linear product should be Less than 2/3 of the diameter of the integrating sphere. In the 2π structure, the diameter of the opening where the OLED panel is installed should be less than 1/3 of the diameter of the integrating sphere. If the OLED size exceeds these values, it can be measured with a smaller light source, and preferably a similar smaller OLED. first First, place the small light source in the center for measurement, and then place the small light source on the edge of the large-size OLED panel for measurement. Line measurement. If the difference in the measurement results is less than 1%, the large-size OLED panel can be measured with this integrating sphere, and no additional Correction. If the error exceeds 1%, the integrating sphere needs to be calibrated according to this size of OLED. The recommended method for this calibration is to use a distribution Type photometer to measure OLED. After calibration, this integrating sphere can be used to measure OLEDs of this size. It should be noted that for low-brightness OLEDs and small-size OLEDs, because they emit less light in the integrating sphere, the measurement may not be correct. accurate. A.3 Goniophotometer measurement According to GB/T 26178-2010. It is difficult to measure large-size OLED panels with an integrating sphere. In this case, it is appropriate to use a Goniophotometer to measure. Of course However, the Goniophotometer also has problems when measuring all the light emitted from the side. A reliable calibration method is under consideration. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 39930-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 39930-2021_English as soon as possible, and keep you informed of the progress.
