In this embodiment, the inverted new source control signal VCT_EN1 (or VCT_EN6) will serve as the control signal of the charge sharing switch circuit 133% to determine the conduction of each switching transistor in the charge sharing switch circuit 133%. Cutoff status. Here, since the on/off state of the charge sharing switch circuit 133% is opposite to the on/off state of the channel switch circuit 1339a, the source drive integrated circuit X1 (or Χ6) stops supplying the display data to the data line "DL". The data line DL can be charge-shared with a preset potential such as vc〇M or AGND to effectively eliminate the image sticking phenomenon in the display process of the active matrix display. • The main control logic circuit 132 shown in FIG. The non-gate and the gate are used to perform a gate operation on the output signals VC_0utl~VC_out6 of the respective source drive integrated circuits χι to Χ6, and then perform a gate operation with the initial gate start signal YDIO to obtain a new gate. The pole start signal yDI〇_t is used to determine whether the gate drive integrated circuit γι~γ6 in the gate drive circuit is enabled. It can be seen from Fig. 5 that the output § 凡凡 VC an outl ~ VC_out6 (in Figure 5 It is only shown that at least one of VC_out1 and VC_out6) is at a high level (indicating that the operating temperature of at least one of the source driving integrated circuits XI to X6 is too high), even if the initial gate start signal YDI0 starts the pulse. arrival The new gate start signal 201123132 YDIO_T remains at the low level until the next start pulse and the operating temperatures of all the source drive integrated circuits Χ1~Χ6 are within the operating temperature. In other embodiments, the main control The logic circuit 1320 can also have other suitable circuit structures. For example, when the sensed operating temperature is too high, the output signal vc_〇utl~vc_〇ut6 generated by the corresponding comparator 1333 is a low level instead of the foregoing embodiment. When the high level is on time, the main control logic circuit 132 can adopt the circuit structure shown in Fig. 7. Specifically, the main control logic circuit 132 shown in Fig. 7 includes two φ and gate ' to drive the integrated circuit XI to each source. X6 output signal VC_out 1~VC_out6 performs the gate operation and then the initial gate start signal ^YDI0 to perform the gate operation to obtain a new gate start signal YDIO-T to determine whether to enable the gate The gate in the driving circuit drives the integrated circuits γι~γ6, which can achieve the same purpose. In summary, the embodiment of the present invention configures a temperature sensing control circuit in an active matrix display, thereby sensing when When the temperature of the integrated circuit in the source driving circuit is too high, a corresponding control signal is generated to control the operation of the gate driving circuit to cut off the connection between the source driving circuit and the data line, thereby avoiding the pumping of a large current. The phenomenon that the power consumption is too high and the temperature is too high, so as to effectively avoid the risk of the circuit being burnt due to excessive temperature.
