The working time sequence of the gate line, the reset switch, the CDS1 and the CDS2 is as shown in fig. 5, when the gate line is not in the working state, the reset switch is turned on to release the residual capacitance in the feedback capacitance, so as to avoid the residual capacitance from affecting the accuracy of the current sampling result, the CDS1 and the CDS2 are reset in the reset process, the reset switch is turned off after the reset process is finished, the CDS1 is used for acquiring a reset level signal, the reset level signal is used for indicating a signal corresponding to the leakage current when the laser sensor does not receive the gate signal of the gate line, the working state of the gate line is turned on after the acquisition of the reset level signal is finished, namely, the gate line is made to send the gate signal to the laser sensor, the laser sensor sends the acquired signal to the display circuit, at the moment, the integral amplifier in the display circuit amplifies the signal to obtain a driving level signal, and the CDS2 is used for collecting the driving level signal, namely the level signal sampled this time.

Specifically, the reset level signal is used for indicating the electric energy signal which is left when the illumination sensor is subjected to brightness sampling last time, the drive level signal is used for indicating the electric energy signal which is left when the illumination sensor is subjected to brightness sampling this time, analog-to-digital conversion is carried out on the reset level signal and the drive level signal so as to convert the electric energy signal into data in a digital form, a first numerical value and a second numerical value are obtained, the first numerical value is used for indicating the reset level signal, the second numerical value is used for indicating the drive level signal, in order to eliminate the interference influence of the electric energy signal which is left when the illumination sensor is subjected to brightness sampling last time on the brightness sampling this time, the first numerical value is subtracted from the second numerical value, and therefore the sampling brightness value which is obtained after the interference is eliminated is obtained.

Specifically, the threshold may be customized according to the brightness requirement of the actual application scene, in this application, the threshold is set to be 0, that is, when the brightness difference is greater than or equal to 0, it indicates that the brightness of the illumination sensor corresponding to the brightness difference is greater than the brightness of the reference sensor, and it needs to reflect the brightness difference between the illumination sensor and the reference sensor, the brightness value corresponding to the illumination sensor is updated from the sampled brightness value to the brightness difference, exemplarily, the sampled brightness value of one illumination sensor is 45, and the sampled brightness value of the reference sensor corresponding to the illumination sensor is 41, the difference is obtained as a brightness difference of 45-41-4, 4>0, the brightness value of the illumination sensor is updated from 45 to 4, the brightness difference corresponding to the reference sensor is 0, and the brightness value of the reference sensor is updated to 0, that is, that the brightness of the illumination sensor is still greater than the brightness of the reference sensor, the original brightness difference between the illumination sensor and the reference sensor is maintained.
