With continued reference to fig. 1, the number of rows of pixel cells 130 is greater than the number of columns of pixel cells 130.
Specifically, the driving current of the row driving chip is larger than that required for one row of pixels. When the number of rows of the pixel units 130 is greater than the number of columns of the pixel units 130, by setting an output end of the row driving unit 110 to be electrically connected with the common end C1 of a column of the pixel units 130, the row driving unit 110 can provide driving current for the column of the pixel units 130 through the common end C1 of the pixel units 130, so that the row driving unit 110 can drive more light emitting devices D1, and the resource utilization rate of the row driving unit 110 is improved. Meanwhile, the number of the light emitting devices D1 driven by each row driving unit 110 is increased, so that the number of the row driving units 110 required by the display module can be reduced, and the number of driving units of the display module can be further reduced. In addition, an output end of the column driving unit 120 is electrically connected to the second electrode of the light emitting device D1 with the same light emitting color in the row of pixel units 130, so as to provide driving current for the light emitting device D1 with the same light emitting color in the row of pixel units 130, thereby meeting the requirement of the display module and ensuring the normal display of the display module without increasing the number of the column driving units 120.
Illustratively, the display module may have 48 columns by 135 rows of pixel cells. When an output end of the row driving unit 110 is electrically connected to the common end C1 of the column of pixel units 130, the row driving unit 110 can provide a driving current for a column of 135 light emitting devices D1 through the common end C1, so that the row driving unit 110 can drive more light emitting devices D1 compared with 48 light emitting devices in the prior art, and the resource utilization rate of the row driving unit 110 is improved. When each row driving unit 110 is 8 channels, a total of 6 row driving units 110 are required, so that the number of row driving units 110 required by the display module can be reduced compared with 18 row driving chips required in the prior art, and the number of driving units of the display module can be reduced. Meanwhile, when each pixel unit 130 includes a red light emitting device, a green light emitting device and a blue light emitting device, an output end of the column driving unit 120 is electrically connected to the second electrode of the light emitting device D1 with the same light emitting color in one row of pixel units 130, each column driving unit 120 provides a driving current for 48 light emitting devices D1 with the same color in one row of pixel units 130, so as to ensure the normal display of the display module. When each column driving unit 120 is 16 channels, the light emitting device D1 of the same color requires 9 column driving units 120, and the light emitting devices D1 of three light emitting colors require 9*3 column driving units 120 in total. Compared with the prior art, the display module can meet the requirement of the display module without additionally increasing the number of the column driving units 120.
According to the technical scheme, when the number of rows of the pixel units is larger than the number of columns of the pixel units, the output end of the row driving unit is electrically connected with the common end of a column of the pixel units, so that the row driving unit can drive more light emitting devices, and the resource utilization rate of the row driving unit is improved. Meanwhile, the number of the light emitting devices driven by each row driving unit is increased, so that the number of the row driving units required by the display module can be reduced, and the number of the driving units of the display module is further reduced. In addition, an output end of the column driving unit is electrically connected with the second electrode of the light emitting device with the same light emitting color in one row of pixel units, so that the requirement of the display module can be met on the basis of not additionally increasing the number of the column driving units, and the normal display of the display module is ensured.
With continued reference to fig. 1, the common terminal C1 of the pixel units 130 in the same column and the first connection lines L1 correspondingly connected are distributed in a straight line.
Specifically, the common terminal C1 in the same column of pixel units 130 can be arranged along the column direction, and meanwhile, the first connecting line L1 is set to be a straight line, so that the first connecting line L1 can be prevented from being blocked by other structures when being connected with the common terminal C1 in the extending process, and further, the first connecting line L1 and the common terminal C1 can be prevented from being perforated and replaced, the first connecting line L1 is prevented from being formed by additionally arranging a layer of plates, the circuit design of the circuit connection in the display module is simplified, and the board layer setting required by the display module is reduced. Meanwhile, by arranging the first connecting lines L1 to be distributed in a straight shape along the column direction, the space requirements of different pixel units 130 along the row direction can be reduced, the tight arrangement among the pixel units 130 is facilitated, and the resolution of the display module is improved.

The second connection line L2 extends along the row direction, and is different from the extending direction of the first connection line L1, and by setting the second connection line L2 and the different layer of the pixel unit 130, the line setting of the layer where the pixel unit 130 is located can be simplified, and meanwhile, the phenomenon that the pixel unit 130 is abnormally driven due to the intersecting short circuit of the first connection line L1 and the second connection line L2 can be avoided.

Specifically, the signal connection line L3 may be a clock signal line for providing clock signals to the row driving unit 110 and the column driving unit 120. The signal connection line L3 may include a plurality of signal connection lines L3, and the row driving unit 110 and the column driving unit 120 respectively correspond to different signal connection lines L3, thereby implementing independent control of the row driving unit 110 and the column driving unit 120. The row driving unit 110 supplies a first driving signal to a first electrode of a column of the light emitting devices D1 through the common terminal C1, and the column driving unit 120 supplies a second driving signal to a second electrode of the row of the light emitting devices D1 through the second connection line L2, and simultaneously controls a certain light emitting device D1 to emit light by the first driving signal and the second driving signal. Meanwhile, the light emitting device D1 and the common end C1 of the pixel unit 130 are arranged on the same layer of board, so that the display module can realize normal driving of the pixel unit 130 by only two layers of substrates, the substrates are saved, and the simplified design and the thinned design of the display module are facilitated.

When the pixel unit comprises three light emitting devices with different light emitting colors, the same pixel unit can correspond to the three column driving subunits and is used for respectively driving the three light emitting devices with different light emitting colors in one row of pixel units so as to meet the driving requirement of the display module.
