For output voltage current potential Vsens, and output voltage current potential Vsens exported to the control unit 13 described in Fig. 1 current to judge
The temperature of substrate.
Next please also refer to Fig. 2, Fig. 3 A, Fig. 3 B and Fig. 4.Fig. 3 A are 11 embodiment of temperature sensing circuit of the present invention
First control signal S1 and sensing voltage current potential Vo curve graph at different temperatures, wherein 80 DEG C of Vo@are sensing voltage
Current potential Vo is 80 DEG C of voltage value in temperature, and 25 DEG C of Vo@are sensing voltage current potential Vo in the voltage value that temperature is 25 DEG C, Vo@- 25
DEG C it is sensing voltage current potential Vo in the voltage value that temperature is -25 DEG C.Fig. 3 B are the output voltage current potential Vsens of capacitance C in difference
At a temperature of curve graph, 80 DEG C of Vsens@are voltage values of the output voltage current potential Vsens when temperature is 80 DEG C, 25 DEG C of Vsens@
It is to feel output voltage current potential Vsens in the voltage value that temperature is 25 DEG C ,@- 25 DEG C of Vsens exists for sense output voltage current potential Vsens
Temperature is -25 DEG C of voltage value.Fig. 4 is the operating method step schematic diagram of 11 embodiment of temperature sensing circuit of the present invention.
When first control signal S1 is operating voltage current potential, i.e. marked in Fig. 3 A during A, warming module 112 feels
Survey Current Temperatures and output sensing voltage current potential Vo (steps 300), transistor when first control signal S1 is operating voltage current potential
T2 is opens, and second control signal S2 is close to low voltage potential Vss, and transistor T3 is closes, therefore sensing voltage current potential at this time
The voltage of Vo is charged by high voltage potential Vdd and is begun to ramp up, as shown in the sensing voltage current potential Vo of A between Fig. 3 A mid-terms, not
The sensing voltage current potential Vo sensed when synthermal all rises to higher voltage potential, and transistor T2 and transistor T4 at this time
It opens, therefore transistor T2 outputs one have the second control signal S2 of low voltage potential, and since second control signal S2 is
Low voltage potential, therefore transistor T3 is closes.At this time because transistor T4 is opens, therefore read module 116 is by sensing voltage
Current potential Vo reads and stores to capacitance C (steps 302), so when output voltage current potential Vsens also with sensing voltage current potential Vo
And increase, as shown in Figure 3B.Then when first control signal S1 is low voltage potential, i.e. marked in Fig. 3 A during B, it is brilliant
Body pipe T2 and transistor T4 is closed, and transistor T1 outputs one have the second control signal S2 of operating voltage current potential, therefore brilliant
Sensing voltage current potential Vo is reset to low voltage potential by body pipe T3 to open, such as the sensing voltage current potential Vo of B between Fig. 3 A mid-terms
Shown, the sensing voltage current potential Vo under different temperatures is all reset as low voltage potential (step 304), at this time and by capacitance C institutes
The output voltage current potential Vsens of storage is exported to the 13 (step 306) of control unit described in Fig. 1, makes control unit 13 can be according to this
The Current Temperatures of substrate 10 are obtained, the output voltage current potential Vsens after the completion of output stored by capacitance C turns again to a low-voltage
Current potential, as shown in the output voltage current potential Vsens of B between Fig. 3 B mid-terms, at the end of period B, the output voltage electricity of different temperatures
The voltage potential of position Vsens all drops to corresponding low voltage potential.In addition, A and Fig. 3 B according to fig. 3, no matter in high temperature 80
DEG C or -25 DEG C of low temperature in the case of, the present invention all can export corresponding sensing voltage current potential Vo according to presently sensed temperature, because
This control unit 13 can be according to the output voltage current potential Vsens received, such as the electricity of the Vsens=13.4V marked in Fig. 3 B
Pressure value, to obtain the sensing result that Current Temperatures are 80 DEG C, therefore the present invention significantly has wider temperature detection range.
Comprehensive the above, since the temperature sensing circuit embodiment of the present invention is disposed on the substrate in display, because
This temperature sensing circuit can directly and accurately detect the Current Temperatures of substrate, and the warming module of temperature sensing circuit is by more
The diode of a concatenation is made of the transistor of multiple concatenations, therefore with higher warming sensitivity, makes the present invention's
Temperature sensing circuit embodiment is more accurately examined without additionally feeling the purpose of sensitivity using elements such as amplifiers to reach a high temperature
Current Temperatures are measured, display is reduced and happening for mistake is shown due to temperature changes.In addition, the temperature sensing electricity of the present invention
Road embodiment only needs that by a first control signal temperature sensing can be carried out, and the convenience of temperature sensing is significantly increased.
Again since the leakage current of the capacitance in low temperature is smaller, the capacitance with relatively low capacitance is in low temperature with the spirit of preferable warming
Sensitivity, and the leakage current of capacitance is larger during high temperature, the capacitance with higher capacitance value is sensitive with preferable warming at high temperature
Degree, therefore be intended to judge the mode of Current Temperatures using characteristic of the capacitance at different temperatures with different leakage currents, need to select can
The capacitance of warming sensitivity when taking into account low temperature and high temperature, this measure can then lead to the electricity of capacitance changed to sensing temperature
Capacitance is restricted, and in turn results in that the temperature that can be sensed is limited, and the temperature sensing circuit embodiment of the present invention is to utilize
The sensing voltage current potential that warming module is sensed judges the temperature of current substrate, and this case is without in order to select preferable warming spirit
Sensitivity and select specific capacitance, also would not be because of specific capacitance and with smaller temperature sensing range, therefore
This case has more wider detection temperature range.
Although the present invention has been disclosed by way of example above, it is not intended to limit the present invention., any people in the art
Member, without departing from the spirit and scope of the present invention, when can do a little change and retouching, therefore protection scope of the present invention is worked as
It is subject to claims.
