It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, a Gate On Array (GOA) circuit has the advantages of lower cost, better display effect and capability of reducing the frame of a display panel, compared with a COF circuit, and has been widely applied to Gate driving of display panels. Fig. 2 is a schematic timing diagram illustrating two continuous and cascaded GOA units in a GOA circuit overlapping each other in a preset timing, and as shown in fig. 2, in order to increase the precharge time of the cascaded GOA units in the GOA circuit, multiple cascaded GOA units of the GOA circuit often overlap each other in the preset timing, so that even if the GOA circuit is applied to the light sensing driving circuit in the prior art in fig. 1 instead of the COF circuit, the multiple GOA units overlapping each other in the preset timing may cause a conflict when multiple photodetectors respectively connected to the multiple GOA units read on a common data line, and therefore, a driving method of the GOA circuit cannot be introduced into the light sensing driving circuit in the prior art in fig. 1.
In view of the above, an embodiment of the present invention provides a light sensing driving circuit, and fig. 3 is a schematic diagram illustrating an overall structure of the light sensing driving circuit provided in the embodiment of the present invention, as shown in fig. 3, the light sensing driving circuit is electrically connected to an output terminal of the GOA circuit by using a driving method of the GOA circuit, and data output of the light sensing module 1 is controlled by an output signal of the GOA circuit.

It is understood that there is no overlap between the output signals of each M consecutive cascaded GOA units at the preset timing, i.e. there is no overlap iN the preset timing for the output signals G (iN), G (iN +1) … … G (iN + M) of different groups of M consecutive cascaded GOA units.
Furthermore, the light sensing driving circuit comprises a reading module 3, a plurality of light sensing modules 1 and a plurality of data lines 4, wherein each light sensing module 1 is electrically connected to an output end of one GOA unit, the M light sensing modules 1 are respectively and electrically connected to output ends of the M GOA units in each GOA module, and the M light sensing modules 1 are respectively and electrically connected to the reading module 3 through one data line 4 different from each other, so that during a period that output signals G (N), G (N +1) … … G (N + M) of the M GOA units are overlapped on a preset time sequence, the M light sensing modules 1 respectively and electrically connected to the M GOA units can simultaneously transmit data to the reading module through one data line 4 different from each other, and thus data in the light sensing modules 1 can be simultaneously acquired and read through the reading module 3, and the problems that the prior art is low in efficiency, and the data of the light sensing modules are only read through one data line are avoided, May interfere with each other.
For example, in the case that every two continuous cascaded GOA cells in the GOA circuit of fig. 2 overlap at a predetermined timing, fig. 4 is a specific structural schematic diagram of the light sensing driving circuit provided in this embodiment of the present invention, and as shown in fig. 4, the light sensing driving circuit is connected to a GOA circuit, where Gate (n) and Gate (n +1) overlap at the predetermined timing, and Gate (n +2) and Gate (n +3) overlap at the predetermined timing, it should be noted that Gate (n +1) and Gate (n +2) do not overlap at the predetermined timing, that is, M is 2 in this embodiment, every two continuous cascaded GOA cells in the GOA circuit overlap at the predetermined timing, Gate (n) and Gate (n +1) in the GOA circuit form one GOA module, and Gate (n +2) and Gate (n +3) in the GOA circuit form the next GOA module, and so on.
The light sensing driving circuit reads data of all light sensing modules by adopting two data lines, and concretely, taking Gate (n), Gate (n +1), Gate (n +2) and Gate (n +3) as an example, each light sensing module is electrically connected with an output end of a corresponding GOA unit, two light sensing modules respectively and electrically connected with Gate (n) and Gate (n +1) are respectively and electrically connected with a reading module through different data lines of the two data lines, and the other two light sensing modules electrically connected with Gate (n +2) and Gate (n +3) are respectively and electrically connected with the reading module through different data lines of the two data lines.
