Detailed Description
An embodiment of the present application provides a driving circuit, as shown in fig. 1, the driving circuit includes: a driver 1, an electrostatic discharge detection circuit 2, an electrostatic discharge protection circuit 3, and a restart circuit 4;
the electrostatic discharge protection circuit 3 and the driver 1 are coupled to the same power supply terminal VCC;
the electrostatic discharge detection circuit 2 is configured to: receiving level signals of the driver 1 and the electrostatic discharge protection circuit 3, and sending a restart signal to the restart circuit 4 when the received level signals of the electrostatic discharge protection circuit 3 and the driver 1 are both low level signals;
the restart circuit 4 is configured to control the driver 1 to restart according to the restart signal.
It should be noted that the driver outputs a high level signal when the driver normally operates, and when Electro-Static discharge (ESD) occurs and the driver is affected to cause data abnormality, the driver outputs a low level signal, and when the ESD does not occur, the ESD protection circuit outputs a high level signal, and when ESD occurs, the ESD protection circuit outputs a low level signal.
The driving circuit provided by the embodiment of the application comprises an electrostatic discharge detection circuit, wherein the electrostatic discharge detection circuit receives a signal of a driver and a signal of an electrostatic discharge protection circuit, determines whether an output signal caused by ESD is abnormal or not of a driving electric appliance according to the received signal, and sends a restart signal to a restart module when the output signal caused by ESD is abnormal, so that the driver is controlled to restart, the driver can be automatically restarted under the condition that the driver cannot normally work due to electrostatic influence, a display product is prevented from being continuously in a state of abnormal display or halt, and the normal output of the driver is maintained. And the electrostatic discharge detection circuit determines that the output signal of the drive circuit is abnormal due to ESD only under the condition that the signal of the driver and the signal of the electrostatic discharge protection circuit are both low level, so that the detection accuracy can be improved, the condition that the signal transmission is abnormal, the power supply circuit is abnormally short-circuited and the like is mistakenly detected as the output signal abnormality due to ESD, and the driver is prevented from being frequently restarted and cannot normally work.
Alternatively, as shown in fig. 2, the electrostatic discharge detection circuit 2 includes: a first inverter 201, a second inverter 202, and a first and gate 203;
an input terminal of the first inverter 201 is coupled to the driver 1, and an output terminal of the first inverter 201 is coupled to a first input terminal of the and gate 203;
an input end of the second inverter 202 is coupled to an output end of the electrostatic discharge protection circuit 3, and an output end of the second inverter 202 is coupled to a second input end of the first and gate 203;
the output terminal of the first and gate 203 is coupled to the restart circuit 4, and the output terminal of the first and gate 203 is configured to output a continuous low level signal or the restart signal.
In the driving circuit provided in the embodiment of the application, when the driver and the electrostatic discharge protection circuit are not affected by ESD and normally operate, the first inverter 201 and the second inverter 202 both input a high level signal and output a low level signal, and the two low level signals are still low level signals output by the first and gate 203, so that the restart circuit 4 is not triggered to control the driver to automatically restart, and the driver keeps normally operating.
When ESD occurs and the driver has an abnormal output signal due to ESD, the first inverter 201 and the second inverter 202 both input a low level signal and output a high level signal, and the output end of the first and gate 203 outputs a high level restart signal, thereby triggering the restart circuit 4 to restart the driver.
When one inverter of the first inverter 201 and the second inverter 202 inputs a low level signal and the other inverter inputs a high level signal, the two input ends of the first and gate 203 respectively input the low level signal and the high level signal after passing through the inverters, and the output end of the first and gate 203 still outputs the low level signal. Therefore, even if the driver outputs a low level signal due to other abnormal conditions, the electrostatic discharge protection circuit outputs a high level signal at the moment, the electrostatic discharge detection circuit cannot be triggered to send a restart signal to the restart module, and the automatic restart of the driver cannot be triggered. Thereby preventing frequent automatic restarts of the drive due to other abnormal conditions. When ESD occurs, if only the electrostatic discharge protection circuit is influenced by the ESD to output low level, and the driver has stronger ESD resistance and is not influenced to normally display, the driver still outputs high level signals, the electrostatic discharge detection circuit cannot be triggered to send restart signals to the restart module, and the driver is prevented from being frequently and automatically restarted.
Alternatively, as shown in fig. 2, the electrostatic discharge protection circuit 3 includes: a first transient voltage suppression diode D1, and a first resistor R1;
a first terminal of the first transient voltage suppression diode D1 is coupled to the power supply terminal VCC, and a second terminal of the first transient voltage suppression diode D1 is grounded GND;

In the driving circuit shown in fig. 2 provided in the embodiment of the present application, when ESD does not occur, the first transient voltage suppression diode D1 is turned off, and the electrostatic discharge protection circuit outputs a continuous high level signal. When ESD occurs, the first transient voltage suppression diode D1 instantaneously conducts, so that the electrostatic discharge protection circuit 3 outputs a low level signal. After the ESD is terminated, the first transient voltage suppression diode D1 returns to the off state, and the electrostatic discharge protection circuit 3 outputs a continuous high level signal.
Optionally, as shown in fig. 2, the first transient voltage suppression diode D1 is a bipolar transient voltage suppression diode.
The driving circuit provided by the embodiment of the application adopts the bipolar transient voltage suppression diode, and the positive and negative high voltages when ESD occurs can enable the bipolar transient voltage suppression diode to be instantly conducted, so that the electrostatic discharge detection circuit outputs a low-level signal, the protection effect of the electrostatic discharge detection circuit on the occurrence of ESD can be realized, and the electrostatic discharge detection circuit can determine whether the output signal caused by electrostatic discharge occurs to the driving electrical appliance according to the signal of the driver and the signal of the electrostatic discharge protection circuit.
Optionally, the turn-on voltage of the first transient voltage suppression diode D1 is equal to a preset esd detection criterion.
For example, when the predetermined esd detection criterion is ± 2 Kilovolts (KV), the turn-on voltage of the first transient voltage suppression diode D1 is ± 2 KV. When ESD occurs, the first transient voltage suppression diode D1 is conducted, the electrostatic discharge detection circuit outputs a low level signal, if the driver cannot pass the test of +/-2 KV, the driver outputs a low level signal when the driver is abnormal, the first inverter and the second inverter both input the low level signal and output a high level signal, the first AND gate outputs a high level restart signal, and the restart circuit is triggered to restart the driver, so that the driver is automatically restarted by the abnormal signal of the driver when ESD occurs. Therefore, the purposes of protecting and maintaining the normal output of the driver and passing the ESD test are achieved, and the driving circuit provided by the embodiment of the application can be suitable for the extremely high ESD test.
Alternatively, as shown in fig. 2, the restart circuit 4 includes: a driver main chip 401 and a Flash memory chip (Flash) 402; the flash chip 402 stores a restart program for controlling the driver 1 to restart, and the driver master chip 401 is configured to: and reading the restart program from the flash chip 402 according to the restart signal, and controlling the driver 1 to restart.
Optionally, as shown in fig. 3, the driving circuit further includes: a timing control circuit 5 coupled to the driving master chip and the driver; the driving main chip is specifically used for: and controlling the sequential control circuit block to be powered on after power failure according to the restart program so as to control the driver to restart.
Optionally, as shown in fig. 2 and fig. 3, the Driver 1 includes a plurality of cascaded source drivers, and the source Driver N at the last stage is coupled to the electrostatic discharge detection circuit 2.

s101, the electrostatic discharge detection circuit determines whether the driver has output signal abnormity caused by electrostatic discharge according to the received level signals of the driver and the electrostatic discharge protection circuit;

and S103, the restarting circuit controls the driver to restart according to the restarting signal.
According to the method for restarting the driving circuit, whether the output signal abnormality caused by ESD occurs to the driving electric appliance or not is determined by the electrostatic discharge detection circuit according to the received signal, when the output signal abnormality caused by ESD occurs to the driver, the restarting signal is sent to the restarting module, and the restarting module controls the driver to restart according to the restarting signal, so that the driver can be automatically restarted under the condition that the driver cannot normally work due to the influence of static electricity, and the display product is prevented from being continuously in a state of abnormal display or dead halt. And the electrostatic discharge detection circuit determines that the output signal of the drive circuit is abnormal due to ESD only under the condition that the signal of the driver and the signal of the electrostatic discharge protection circuit are both low level, so that the detection accuracy can be improved, the condition that the signal transmission is abnormal, the power supply circuit is abnormally short-circuited and the like is mistakenly detected as the output signal abnormality due to ESD, and the driver is prevented from being frequently restarted and cannot normally work.
In specific implementation, when it is determined that the driver is not abnormal in output signals due to electrostatic discharge, the electrostatic discharge protection circuit outputs a continuous low-level signal to the restart circuit, and the restart circuit is not triggered to restart the driver.
