Please refer to Fig. 1, Fig. 1 illustrates the synoptic diagram of
display device100 of the amorphous silicon of the embodiment of the
invention.Display device100 has amorphous
silicon display panel160, and
display device100 also comprises
driving governor110,
temperature sensor120, main
gate pole driver130,
auxiliary gate driver140 and commutation circuit 150.And in the present embodiment, main
gate pole driver130,
auxiliary gate driver140 and amorphous
silicon display panel160 all are configured on the identical
amorphous silicon substrate170.
In addition, main
gate pole driver130 and
auxiliary gate driver140 are coupled to amorphous silicon display panel 160.Illustrate that more more specifically main
gate pole driver130 and
auxiliary gate driver140 are a plurality of thin film transistor (TFT)s (not illustrating) that are coupled in the amorphous silicon display panel 160.Main
gate pole driver130 and
auxiliary gate driver140 also connect and are coupled to driving
governor110 to receive drive control signal DCTRL.150 of commutation circuits are coupled to
temperature sensor120, and are coupled between the path of
auxiliary gate driver140 reception drive control signal
DCTRL.Commutation circuit150 receives the switch-over control signal CS that
temperature sensor120 is produced, and comes conducting or disconnect the path that
auxiliary gate driver140 receives drive control signal DCTRL according to switch-over control signal CS.
Driving
governor110 is in order to produce drive control signal DCTRL.Drive control signal DCTRL is used for controlling main
gate pole driver130 or
auxiliary gate driver140 drives amorphous silicon display panel 160.Wherein, drive control signal DCTRL comprise frequency signal CLK, reverse frequency signal CLKB, initial pulse wave signal STP with gate drive voltage VGL.Frequency signal CLK and reverse frequency signal CLKB are used to provide to main
gate pole driver130 or the
auxiliary gate driver140 driving order with the gate sweep trace (gate line) that produces amorphous
silicon display panel160, initial pulse wave signal STP then will produce voltage source with the driving voltage that drives the thin film transistor (TFT) in the amorphous
