In one embodiment, as shown in fig. 1, a data processing method is provided, and the method is applied to the display panel in fig. 1 for illustration, and includes the following steps:
step 102, obtaining sampling brightness values corresponding to a plurality of illumination sensors in a display panel.

Specifically, each illumination sensor corresponds to a display circuit, the display circuit is electrically connected with the gate line and the data line, the display circuit is used for adjusting driving voltage according to the gate signal transmitted by the gate line and the data signal transmitted by the data line, the sensing brightness of the illumination sensor is adjusted by changing the driving voltage of the display circuit, the sampling brightness value can be determined according to the driving voltage of the display circuit, and generally, the larger the driving voltage is, the higher the corresponding sensing brightness is, namely the larger the illumination intensity is.
And 104, determining brightness differences between the illumination sensors and the reference sensors in the same row based on the sampling brightness values corresponding to the illumination sensors.
Wherein the reference sensor is any one of the plurality of illumination sensors corresponding to each row.
Specifically, one illumination sensor is arbitrarily selected from the plurality of illumination sensors in each row as a reference sensor, the sampled luminance value corresponding to each illumination sensor in each row is differenced from the sampled luminance value corresponding to the reference sensor, so as to obtain luminance differences between each illumination sensor and the reference sensor, for example, one row in the display panel comprises five illumination sensors, the sampled luminance values corresponding to the five illumination sensors in the first row are respectively 30, 31, 32, 33 and 34, wherein the illumination sensor corresponding to 30 is selected as the reference sensor in the first row, the sampled luminance value corresponding to the fifth illumination sensor in the second row is respectively 20, 21, 22, 23 and 24, the sampled luminance value corresponding to the 20 illumination sensor is selected as the reference sensor in the second row, and the luminance differences of 0, 1, 2, 3 and 4 corresponding to each illumination sensor in the first row and the luminance differences of 0, 1, 2, 3 and 4 corresponding to the fifth illumination sensor in the second row are respectively obtained after the sampled luminance value corresponding to the 20 illumination sensor and the sampled luminance value corresponding to the reference sensor are differenced.
And step 106, updating the brightness value corresponding to each illumination sensor from the sampling brightness value to the brightness difference value.
Specifically, referring to the above example, the luminance difference between the plurality of illumination sensors in the first row is small, but the luminance difference between the illumination sensors in the first row and the illumination sensors in the second row is large, the luminance value of each illumination sensor is updated from the sampled luminance value to the luminance difference, and illustratively, the luminance values corresponding to the five illumination sensors in the first row are modified from original 30, 31, 32, 33, 34 to 0, 1, 2, 3, 4, the luminance values corresponding to the five illumination sensors in the second row are modified from original 20, 21, 22, 23, 24 to 0, 1, 2, 3, 4, before the luminance values of the illumination sensors in the first row are updated, the luminance difference between the luminance values corresponding to the illumination sensors in the first row and the luminance values corresponding to the illumination sensors in the second row is equal to or greater than 10, but after the luminance values of the illumination sensors in the same row are updated by using the luminance difference between the illumination sensors in the first row, the brightness difference between the brightness value corresponding to the first row of illumination sensors and the brightness value corresponding to the second row of illumination sensors is smaller than or equal to 4, and only two rows of illumination sensors are used for illustration, namely, all the row of illumination sensors in the display panel can adjust the brightness value according to the flow, therefore, as the brightness difference between the illumination sensors in the same row is smaller and the brightness difference between the illumination sensors in different rows is larger, the brightness value corresponding to the illumination sensors is updated through the brightness difference between the illumination sensors in the same row, the brightness difference with smaller value between the illumination sensors in the same row is used as the brightness value after the illumination sensors are updated, the brightness difference between the illumination sensors in different rows is eliminated by utilizing the characteristic of smaller brightness difference between the illumination sensors in the same row, the brightness values corresponding to the illumination sensors of different rows are smaller in value, so that the brightness difference between the illumination sensors of different rows is reduced, the induction noise of the photoelectric sensors in the display panel is reduced, and the signal-to-noise ratio of the photoelectric sensors in the display panel is improved.

Specifically, as shown in fig. 4, when the gate line is in an off state, that is, when the display circuit does not detect a gate signal, the reset switch is closed to enable the illumination sensor to be in a reset state, the feedback capacitor releases the electric energy stored in the last sampling, so as to realize the capacitor reset of the feedback capacitor, avoid that the electric energy stored in the feedback capacitor influences the accuracy of the current brightness sampling result when the illumination sensor performs brightness sampling last time, the released electric energy is transferred to the double sampling circuit through the amplification processing of the integrating amplifier, the double sampling circuit comprises two sub-sampling circuits, namely CDS1 and CDS2, respectively recorded as CDS1 and CDS2, and the CDS1 is used for sampling signals of different types, and is used for acquiring reset level signals when the illumination sensor is in the reset state, that is, the electric energy released by the feedback capacitor becomes the reset level signals through the amplification processing of the integrating amplifier.
When the grid line is in a conducting state, the reset switch is in an off state, at the moment, the grid line transmits a grid signal to the laser Sensor (Sensor), the laser Sensor transmits a signal to the display circuit again, the signal is amplified by the integrating amplifier in the display circuit to obtain a driving level signal, and at the moment, the driving level signal is collected through the CDS2, namely, the CDS2 is used for collecting the driving level signal when the illumination Sensor is in a grid signal driving state.
The working time sequence of the gate line, the reset switch, the CDS1 and the CDS2 is shown in fig. 5, when the gate line is not in an on working state, the reset switch is closed and conducted to release residual capacitance in the feedback capacitance, the residual capacitance is prevented from affecting the accuracy of the sampling result, the reset switch is also turned off after the reset process is finished, the CDS1 and the CDS2 are also reset, a reset level signal is collected by the CDS1 and is used for indicating a signal corresponding to leakage current when the laser sensor does not receive the gate signal of the gate line, the working state of the gate line is started after the collection of the reset level signal is finished, namely the gate line is enabled to send the gate signal to the laser sensor, the laser sensor sends the collected signal to the display circuit, an integrating amplifier in the display circuit amplifies the signal at the moment to obtain a driving level signal, and the CDS2 is used for collecting the driving level signal, and the sampled level signal at the moment is obtained.
The method does not need to carry out extra panel circuit design, reduces the manufacturing cost of the display panel, can be applied to different types of display panels, and has higher applicability.

Specifically, the reset level signal is used for indicating the remaining electric energy signal when the illumination sensor is subjected to brightness sampling last time, the driving level signal is used for indicating the remaining electric energy signal when the illumination sensor is subjected to brightness sampling this time, the reset level signal and the driving level signal are subjected to analog-to-digital conversion so as to be converted into digital data, 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 driving level signal, and in order to eliminate the interference influence of the remaining electric energy signal of the previous brightness sampling on the current brightness sampling, the first numerical value is subtracted from the second numerical value, so that the sampling brightness value obtained by the current sampling after the interference is eliminated is obtained.
In one embodiment, before determining the brightness difference between each of the illumination sensors and the reference sensor in the same row based on the sampled brightness values corresponding to the plurality of illumination sensors, the method further includes: and taking the first illumination sensor in the plurality of illumination sensors corresponding to each row as the reference sensor.
Specifically, the first illumination sensor in each row is selected as the reference sensor, and the last illumination sensor in each row can also be selected as the reference sensor, so that the reference sensors in each row are uniformly selected, and the brightness difference value between the illumination sensors in each row can be conveniently and quickly calculated.
In one embodiment, the updating the brightness value corresponding to each illumination sensor from the sampled brightness value to the brightness difference value includes: and when the brightness difference value is greater than or equal to a threshold value, updating the brightness value corresponding to the illumination sensor from the sampling brightness value to the brightness difference value.
Specifically, the threshold may be customized according to the brightness requirement of the actual application scene, in this application, when the threshold is made to be 0, that is, the brightness difference value is greater than or equal to 0, which means that the brightness of the illumination sensor corresponding to the brightness difference value is greater than the brightness of the reference sensor, the brightness difference between the illumination sensor and the reference sensor needs to be represented, then the brightness value corresponding to the illumination sensor is updated from the sampled brightness value to the brightness difference value, and in an exemplary manner, the sampled brightness value of one illumination sensor is 45, and the sampled brightness value of the corresponding reference sensor is 41, then the difference is obtained, the brightness difference value is 45-41=4, 4>0, then the brightness value of the illumination sensor is updated from 45 to 4, and the brightness difference value of the reference sensor is 0 after being updated, that is, the brightness of the illumination sensor is still greater than the brightness of the reference sensor, and the original brightness difference between the illumination sensor and the reference sensor is maintained.

Specifically, when the luminance difference value is smaller than 0, the luminance of the corresponding illumination sensor representing the luminance difference value is smaller than the luminance of the reference sensor, the luminance of the illumination sensors smaller than the luminance of the reference sensor are unified according to the luminance of the reference sensor, namely, the threshold value 0 is assigned to the luminance difference value, so that the luminance corresponding to the illumination sensor is equal to the luminance of the reference sensor, and the luminance value of the sampling luminance value of one illumination sensor is 28, the luminance value of the sampling luminance value of the corresponding reference sensor is 30, the difference is obtained to obtain the luminance difference value of 28-30= -2, -2<0, the luminance difference value=0, the luminance value of the reference sensor is 0, and the luminance value of the reference sensor is updated to be 0 from the original 28, namely, the luminance of the illumination sensor is equal to the luminance of the reference sensor.
