Embodiment Construction

[0045] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0046] figure 1 For the flow chart of OLED model parameter extraction method according to the present invention, reference will be made below figure 1 , the OLED model parameter extraction method of the present invention is described in detail.

[0047] First, in step 101, a parameter extraction model is established. In this step, an OLED extraction model is established to separate the parameter extraction of I-V (current-voltage) and C-V (capacitance-voltage).

[0048] In the embodiment of the present invention, for I-V extraction, a resistor r1iv is connected in series on the OLED device, then a leakage resistor r2iv is connected in parallel between the OLED and...

Abstract

The invention discloses an OLED model parameter extraction method. The method comprises the following steps: 1) establishing a parameter extraction model; (2) confirming a parameter type and an initial value, (3) establishing an error function reflecting a difference value between a measured value and the simulation value, and (4) carrying out optimization solution by adopting an L-M method and asimplex method. By means of the OLED model parameter extraction method, the workload and time of manual parameter adjustment can be reduced, and efficiency is improved.

Description
