The lattice pen 200 may be an infrared lattice pen, and the lattice pen 200 is capable of emitting light of a specific wavelength and receiving a light signal captured to be reflected or projected and converting the light signal into an electrical signal.
Referring to fig. 2, the lattice pen 200 includes a communication unit 201, a processor 202, a high-speed camera 203, a pressure sensor 204 and a memory 205, wherein the processor 202 is electrically connected to the communication unit 201, the high-speed camera 203, the pressure sensor 204 and the memory 205.

Referring to fig. 1 and fig. 3-9, the display module 101 may include a plurality of pixel units 11, and the pixel units 11 may be AMOLED pixel units. The plurality of pixel units 11 are disposed in an array along a first direction and a second direction, respectively, and the first direction and the second direction may be perpendicular to each other, for example, the first direction may be a lateral direction of the display panel 10, the second direction may be a longitudinal direction (vertical direction) of the display panel 10, or the first direction may be a longitudinal direction of the display panel 10, and the second direction may be a lateral direction of the display panel 10.

It will be appreciated that the specific number of pixel units 11 in the pixel group 111 is not limited, and may be set according to the accuracy requirement of the lattice pen 200, i.e. the higher the accuracy of the lattice pen 200, the fewer the number of pixel units 11 in the pixel group 111, and the lower the accuracy, the more the number of pixel units 11 in the pixel group 111.
The coordinate positioning module 105 may include a plurality of lattice units 12, where the plurality of lattice units 12 are arrayed along a first direction and a second direction, a projection of each lattice unit 12 in a third direction is located in one pixel group 111, and each lattice unit 12 has a different pattern, and each lattice unit 12 may absorb or reflect light with a specific wavelength (light emitted by the lattice pen 200). The third direction may be a direction perpendicular to the display panel 10, and the third direction may be perpendicular to the first direction and the second direction.

Specifically, when the lattice pen 200 scans the lattice unit 12 using light of a specific wavelength, the pattern of the lattice unit 12 can be recognized, so that coordinate positioning can be achieved. For example, the infrared lattice pen 200 emits light of a specific wavelength to the lattice unit 12 on the display screen, captures the reflected or projected light signal by the optical sensor, and converts the light signal into an electrical signal, thereby obtaining coordinates of the lattice pen 200 on the display panel 10.

Specifically, each of the row lattice 121 and the column lattice 122 may be composed of a plurality of lattice code patterns, wherein the patterns of the row lattice 121 and the column lattice 122 may be different from each other, for example, the lattice code pattern of the row lattice 121 is square and the lattice code pattern of the column lattice 122 is rectangular; the patterns of the row lattice 121 and the column lattice 122 may also be different in that each of the dot patterns in the row lattice 121 is identical to the dot pattern in the column lattice 122, but the position distribution of the dot pattern in the row lattice 121 is different from the position distribution of the dot pattern in the column lattice 122, as shown in fig. 4 and 5.
Referring to fig. 1 and fig. 9-11, in some embodiments, the plurality of lattice units 12 are arranged in an array to form a plurality of rows and a plurality of columns, and the row lattice 121 and the column lattice 122 located in the same row and the column lattice are identical in pattern. The patterns of the row lattice 121 of the lattice cells 12 in the different rows are different and the patterns of the column lattice 122 of the lattice cells 12 in the different columns are different.
In this way, the rows and columns of the lattice pen 200 can be determined according to the row lattice 121 and the column lattice 122 of the lattice unit 12, and the patterns of the row lattices 121 of different rows are different, so that the row lattice 121 of each row represents a certain abscissa, and the occurrence of error in the identification of the abscissa is avoided, and the patterns of the column lattices 122 in the lattice units 12 of two adjacent columns are different, so that the column lattice 122 of each row represents a certain abscissa, and the occurrence of error in the identification of the ordinate is avoided.
