The voltage threshold or voltage threshold scope that the real-time comparison voltage signal of processing module 250 prestores with correspondence position signal, when described
Processing module 250 judges the roller 230 to the flexibility
The pressure of oled panel 291 when improper the processing module 250 send a signal to the adjusting module in real time
260, the adjusting module 260 adjusts pressure of the roller 230 to the flexible OLED panel 291 in real time, such a mode, leads to
Cross and the pressure that roller 230 is applied in flexible OLED panel 291 is adjusted in real time, so as to avoid current flexibility
Oled panel 291 damages during fitting, so as to improve yields.But such a laminating type is due in adjustment mould
Fitted to when block 260 is adjusted to the roller 230, it is necessary to suspend flexible OLED panel 291 on curved surface cover plate 292, so as to
By flexible OLED panel 291 completely fit on curved surface cover plate 292 take it is longer, be unfavorable for the raising of efficiency and production capacity.
In addition, in other embodiments of the invention, in order to improve fitting efficiency, in the present embodiment, the processing mould
The electric signal and position signalling of block real-time reception piezoelectricity modular converter, it is described after the electric signal and position signalling is received
Processing module is cached or stored without processing, such as by these signals, is fitted to by the flexible OLED panel
After on the curved surface cover plate, a piece of flexible OLED panel carries out being bonded the telecommunications that foregoing description processing module calls storage under
Number and position signalling, concentrate and the electric signal and position signalling handled, now memory module can store substantial amounts of electricity
Signal and position signalling corresponding with electric signal, the processor are handled these data one by one, when the processing module
Judge that corresponding voltage signal is beyond corresponding threshold voltage or threshold in some position signalling either some position signalling
Threshold voltage scope, namely the processing module judge that the roller does not conform in some positions to the pressure of the flexible OLED panel
The processing module sends adjustment signal to the adjusting module in good time, and the adjustment signal is for example including roller in which position
Pressure is excessive etc., and the adjusting module adjusts pressure of the roller to the flexible OLED panel.In the present embodiment due to
Flexible OLED panel is just adjusted after fitting to the curved surface cover plate, and the flexible OLED panel damage above pasted occurs unavoidably
Bad situation, but flexible OLED panel can be improved and fit to the efficiency of curved surface cover plate, and after being adjusted, flexibility below
Oled panel is less likely to be damaged during fitting.
