[0415] The present invention Figure 4 When at least one embodiment of the shown display module is working, each column current supply tube can be a PWM (pulse width modulation) constant current tube, that is, the display brightness of each light-emitting diode can be controlled by the driving current and the light-emitting time of each light-emitting diode.

[0416] The display device described in the embodiment of the present invention includes the above-mentioned display module.

[0417] The display device described in at least one embodiment of the present invention may further include a memory; the memory is a P-bit memory; P is a positive integer;

[0418] The P1-bit storage space in the memory is used to store first data, and the P2-bit storage space in the memory is used to store second data; P1 and P2 are positive integers, and the sum of P1 and P2 is equal to P;

[0419] The first data includes the brightness data of each sub-frame in one frame time;

[0420] The second data includes the average current data corresponding to the brightness.

[0421] In at least one embodiment of the present invention, the average current data can be related to the duty cycle data of the average current flowing through the light-emitting element, and the duty cycle can be the ratio of the light-emitting time of the light-emitting element to the duration of the corresponding light-emitting stage during the corresponding light-emitting stage.

[0422] The control method of the display device described in the embodiment of the present invention is applied to the above-mentioned display device, and one frame time includes multiple sub-frames; the control method includes:

[0423] In each of the sub-frames, display control is performed according to the brightness data corresponding to the sub-frame stored in the memory and the corresponding average current data stored in the memory;

[0424] The memory is a P-bit memory;

[0425] The P1-bit storage space in the memory stores first data, and the P2-bit storage space in the memory stores second data; P1 and P2 are positive integers, and the sum of P1 and P2 is equal to P.

[0426] In at least one embodiment of the present invention, when the light-emitting elements in the same row are electrically connected to R row processing units, the second data includes R groups of second sub-data; the P2-R+1-bit storage space in the memory is used to store a group of second sub-data;

[0427] R is an integer greater than 1. In a specific implementation, when the light-emitting elements in the same row are electrically connected to R row processing units, the second data may include R groups of second sub-data, and a group of second sub-data is stored in the P2-R+1 bit storage space in the memory, so as to ensure the display accuracy while not increasing the storage capacity and reducing the cost.

[0428] For example, the common refresh rate of the chip can be 3840Hz, and the display frequency can be 60Hz. Then one frame time includes 64 sub-frames. The memory can be a 16-bit register, and 6 bits (bits) of the storage space in the register can be used to store the brightness data corresponding to the 64 sub-frames in one frame time. If the storage space less than 6 bits in the register stores the brightness data, it may cause moiré patterns. The 6-bit storage space is 2 6 storage spaces, that is, 64 storage spaces;

[0429] When the light-emitting elements in the same row are electrically connected to one row processing unit, the register can store the average current data corresponding to 1024-order accuracy; 1024 orders is 2 10 orders, and the average current data corresponding to 1024-order accuracy occupies 10 bits of storage space;

[0430] When the light-emitting elements in the same row are electrically connected to two row processing units, that is, when R is equal to 2, the register can store two groups of average current data corresponding to 512-order accuracy, so as to ensure the display accuracy while not increasing the storage capacity and reducing the cost; 512 orders is 2 9 orders, and the average current data corresponding to 512-order accuracy occupies 10 bits of storage space, and two groups of average current data corresponding to 512-order accuracy occupy 10 bits of storage space;

[0431] When the light-emitting elements in each row are electrically connected to more than three row processing units, the capacity of the memory can be expanded to ensure the display accuracy. For example, when the light-emitting elements in each row are electrically connected to four row processing units, the memory can be set as an 18-bit register, 6 bits of the storage space in the register is used to store the brightness data corresponding to the 64 sub-frames in one frame time, and the register stores four groups of average current data corresponding to 1024-order accuracy.

[0432] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
