The invention provides a system for measuring the service life of an OLED screen. The system comprises a gantry rack, an XYZ movement mechanism, a measuring assembly, a heating cavity, a signal generator, a temperature heating control module and a jig for fixing the OLED screen, wherein the XYZ movement mechanism is erected on a gantry rack; the measuring assembly is connected with the XYZ movement mechanism; the temperature heating control module and the jig are arranged in the heating cavity; and the signal generator is connected with the OLED screen placed in the heating cavity. The signalgenerator comprises an FPGA main board, a plurality of FPGA signal boards and a plurality of signal rotating boards. The FPGA main board is connected with the plurality of FPGA signal boards, one FPGAsignal board is correspondingly connected with one signal rotating board, and one signal rotating board is correspondingly connected with one OLED screen placed in the heating cavity. The system hasthe beneficial effect that the efficiency of measuring the service life of the OLED screen is improved.
Description
technical field [0001] The invention relates to a life measuring system, in particular to an OLED screen life measuring system. Background technique [0002] Because OLED has the characteristics of low power consumption, thin thickness, pure and delicate color, and bendability, more and more displays are now using OLED screens. The OLED screen is an organic self-luminous display, and each pixel is independent and can be turned on or off individually. Since each pixel is self-illuminating, instead of the whole block being bright like LCD, this will cause OLED to light up every time. The working time of each pixel is different. If some pixel displays blue for a long time, its blue attenuation will be more than other pixels. When it displays blue in the future, the blue of this pixel will be It is a little lighter than the rest, and the same red and green are the same, so one phenomenon that OLED is prone to is burn-in (the residue caused by uneven aging of the screen). OLED ...
