Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of display, and in particular, to a display module and a display panel. Background Art

[0002] The light emitting diode (LED) display screen includes multiple unit modules, each of which is composed of multiple row driver chips, multiple column driver chips and multiple LED lamp beads. Thousands of LED lamp beads each emit light of a specified color, which can enable the LED display screen to display a frame of an image. When the unit module emits light of a specified color, the LED display screen can use a dynamic scanning method to drive the LED lamp beads to emit light. For example, the LED display screen can use an 8-scan dynamic scanning method to drive the LED lamp beads to emit light, that is, each row driver chip is connected to a row of LED lamp beads, and each column driver chip is connected to 8 LED lamp beads in a column. The row driver chip controls a row, and the column driver chip controls the LED lamp beads in a column, thereby driving each LED lamp bead to emit light.

[0003] In the prior art, row driver chips, column driver chips, and multiple LED lamp beads are arranged on a substrate to form a unit module. The substrate is provided with a multi-layer circuit board, and each circuit board layer is used to form different connection lines to realize the connection between the row driver chip and the column driver chip and the multiple LED lamp beads. For example, in the prior art, the circuit connection within the unit module can use a six-layer second-order circuit board to realize the connection between the row driver chip and the column driver chip and the multiple LED lamp beads. This means that the unit module requires too many substrate layers, resulting in complex circuit connections and a complex structure of the display module. Summary of the Invention

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0024] In the prior art, LED display screens are generally 16:9 display screens, and the sizes of the unit modules that make up display screens with different resolutions are different. For example, when the LED display screen is a 16:9 2K standard display screen, the length and height of the unit modules that make up the LED display screen can be 60.8*170.1mm. When the spacing between pixels is set to be approximately equal to 1.26mm, the length of the unit module can be 48 pixels and the height can be 135 pixels. At this time, the unit module has 48 columns * 135 rows of pixels. When the unit module uses a dynamic scanning method to drive the pixels to emit light, the 135 rows of pixels can be divided into three groups, each group having 45 rows of pixels. The pixels in the same column of the 45 rows of pixels are connected to a column of driver chips to form a 45-scan dynamic scanning method. Each pixel can include multiple LED lamp beads with different luminous colors. When each pixel includes red LED lamp beads, green LED lamp beads and blue LED lamp beads, and each column driver chip can include 16 channels, then each group of 48 columns of pixels requires a total of 3*3 column driver chips, and three groups of 48 columns of pixels require a total of 3*3*3 column driver chips. When the row driver chip has 8 channels, each group of 45 rows of pixels requires a total of 6 row driver chips, and three groups of 45 rows of pixels require a total of 18 row driver chips. When forming a unit module, the row driver chip, column driver chip and pixels are arranged on a substrate. The substrate includes a multi-layer circuit board for connecting each channel of the row driver chip to a row of pixels, and the pixels in the same column of the 45 rows of pixels are connected to a column driver chip. In the prior art, the circuit connection within the unit module can use a six-layer second-order circuit board to connect the row driver chip and the column driver chip to multiple LED lamp beads, which means that the unit module requires too many substrate layers, resulting in complex circuit connections and a complex structure of the display module.

[0025] In response to the above technical problems, an embodiment of the present invention provides a display module. Figure 1 Schematic diagram of a partial structure of a display module provided by an embodiment of the present invention. Figure 1 As shown, the display module includes a row driving unit 110, a column driving unit 120, a first connecting line L1 and pixel units 130 arranged in an array; the pixel unit 130 includes at least two light-emitting devices D1 with different luminous colors and a common terminal C1, and the first electrode of each light-emitting device D1 is connected to the common terminal C1; an output terminal of the row driving unit 110 is electrically connected to the common terminal C1 of a column of pixel units 130, and an output terminal of the column driving unit 120 is electrically connected to the second electrode of the light-emitting device D1 of the same luminous color in a row of pixel units 130; the common terminal C1 of the pixel units 130 in the same column is electrically connected through the first connecting line L1, and the first connecting line L1 and the common terminal C1 are arranged on the same layer.

[0026] Specifically, if Figure 1As shown, the display module further includes a substrate 100, which is used to carry a row driving unit 110, a column driving unit 120 and a pixel unit 130. For example, the substrate 100 can be a printed circuit board. The pixel unit 130 can include at least two light-emitting devices D1 with different luminous colors, for example, Figure 1 As shown, the pixel unit 130 may include three light-emitting devices D1 emitting light of different colors: a red light-emitting device, a green light-emitting device, and a blue light-emitting device. The first electrodes of the light-emitting devices D1 within the same pixel unit 130 are connected to the common terminal C1, enabling the light-emitting devices D1 within the pixel unit 130 to be connected to a common electrode. For example, when the first electrode serves as the anode of the light-emitting device D1, the light-emitting devices D1 within the pixel unit 130 can be connected to a common anode. The substrate 100 is also provided with pins C2 for electrically connecting the second electrodes of the light-emitting devices D1 to the row driver unit 110 and the column driver unit 120. In this case, the light-emitting devices D1 within the same pixel unit 130 have a total of m+1 pins C2, where m is the number of light-emitting devices D1 emitting light of different colors within the pixel unit 130. When the pixel unit 130 includes three light-emitting devices D1 emitting light of different colors, the pixel unit 130 has a total of four pins C2: one pin C2 corresponds to the common terminal C1, and the other three pins C2 correspond to the second electrodes of the three light-emitting devices D1, respectively.

[0027] The row driver unit 110 may be a row driver chip. For example, the row driver unit 110 may be a Chiptron 2019 model chip. The display module may include multiple row driver units 110, and the specific number thereof may be determined based on the number of rows of light-emitting devices D1 and the number of rows of light-emitting devices D1 that each row driver unit 110 can drive. When the row driver unit 110 is used to drive the light-emitting devices D1 within a row of pixel units 130, the driving current provided by the row driver unit 110 is greater than the driving current required by the light-emitting devices D1 within a row of pixel units 130. The column driver unit 120 may be a column driver chip. For example, the column driver unit 120 may be a Chiptron 2069 model chip. The display module may include multiple column driver units 120, and the specific number thereof may be determined based on the number of columns of light-emitting devices D1 and the number of columns of light-emitting devices D1 that each row driver unit 110 can drive. When the column driving unit 120 is used to drive at least part of the light emitting devices D1 in a column of pixel units 130 according to the dynamic scanning mode of the display module, the number of light emitting devices D1 driven by the column driving unit 120 is less than the number of light emitting devices D1 driven by the row driving unit 110 .

[0028] In addition, the common terminal C1 can be provided on the surface of the substrate 100, and the common terminal C1 can be directly connected to the first electrode of the light-emitting device D1. For example, the material of the common terminal C1 can be copper foil. On the surface of the substrate 100, the width of the common terminal C1 is relatively large. By forming the first connecting line L1 at the same time as forming the common terminal C1, the first connecting line L1 and the common terminal C1 are arranged on the same layer, which can avoid the first connecting line L1 and the common terminal C1 from being connected by punching and changing layers. This not only ensures the reliability of the first connecting line L1, but also avoids the need to set up an additional layer of board for forming the first connecting line L1, thereby simplifying the circuit design of the circuit connection in the display module and reducing the number of board layers required for the display module, which is beneficial to reducing the number of layers of the substrate, thereby simplifying the structural design of the display module and reducing the cost of the display module. For example, in the prior art, when the circuit connection in the display module adopts a six-layer two-order circuit board design, in this embodiment, by setting the first connecting line L1 and the common terminal C1 on the same layer, the circuit connection in the display module can be optimized to a four-layer one-order circuit board design.

[0029] The technical solution of the embodiment of the present invention is to connect the common ends of the pixel units in the same column through the first connecting line, and the first connecting line is arranged on the same layer as the common end, so as to avoid the first connecting line and the common end being connected by punching and changing layers. This not only ensures the reliability of the first connecting line, but also avoids the need to set up an additional layer of board for forming the first connecting line, simplifies the circuit design of the circuit connection in the display module, and reduces the board layer setting required for the display module, which is beneficial to reducing the number of layers of the substrate, thereby helping to simplify the structural design of the display module and reduce the cost of the display module.

[0030] Continue to refer Figure 1 , the number of rows of pixel units 130 is greater than the number of columns of pixel units 130 .

[0031] Specifically, the driving current of the row driver chip is greater than the driving current required for a row of pixels. When the number of rows of pixel units 130 is greater than the number of columns of pixel units 130, by setting an output terminal of the row driver unit 110 to be electrically connected to the common terminal C1 of a column of pixel units 130, the row driver unit 110 can provide driving current to the column of pixel units 130 through the common terminal C1 of the pixel units 130, allowing the row driver unit 110 to drive more light-emitting devices D1, thereby improving the resource utilization of the row driver unit 110. At the same time, the number of light-emitting devices D1 driven by each row driver unit 110 increases, which can reduce the number of row driver units 110 required for the display module, thereby reducing the number of driver units in the display module. In addition, an output terminal of the column driver unit 120 is electrically connected to the second electrode of the light-emitting devices D1 of the same light-emitting color in a row of pixel units 130, for providing driving current to the light-emitting devices D1 of the same light-emitting color in a row of pixel units 130. This meets the needs of the display module without increasing the number of column driver units 120, ensuring normal display of the display module.

[0032] For example, the display module may have 48 columns and 135 rows of pixel units. When an output terminal of the row driver unit 110 is electrically connected to the common terminal C1 of a column of pixel units 130, the row driver unit 110 can provide a driving current to the 135 light-emitting devices D1 in a column through the common terminal C1. This allows the row driver unit 110 to drive more light-emitting devices D1 than the 48 light-emitting devices driven by the prior art, thereby improving the resource utilization of the row driver unit 110. When each row driver unit 110 has 8 channels, a total of 6 row driver units 110 are required. This can reduce the number of row driver units 110 required for the display module compared to the 18 row driver chips required by the prior art, thereby reducing the number of driver units in the display module. At the same time, when each pixel unit 130 includes a red light-emitting device, a green light-emitting device, and a blue light-emitting device, and one output terminal of the column driver unit 120 is electrically connected to the second electrode of the light-emitting device D1 of the same color in a row of pixel units 130, each column driver unit 120 provides driving current for the 48 light-emitting devices D1 of the same color in a row of pixel units 130, ensuring normal display of the display module. If each column driver unit 120 has 16 channels, the light-emitting devices D1 of the same color require 9 column driver units 120, and the light-emitting devices D1 of the three colors require a total of 9*3 column driver units 120. Compared to the existing technology, the requirements of the display module can be met without increasing the number of column driver units 120.

[0033] The technical solution of this embodiment, when the number of pixel rows exceeds the number of pixel columns, allows the row drive unit to drive more light-emitting devices by electrically connecting an output terminal of the row drive unit to the common terminal of a column of pixel units, thereby improving the resource utilization of the row drive unit. At the same time, the number of light-emitting devices driven by each row drive unit increases, which can reduce the number of row drive units required by the display module, thereby reducing the number of drive units in the display module. Furthermore, the output terminal of the column drive unit is electrically connected to the second electrode of the light-emitting devices of the same luminous color in a row of pixel units. This can meet the needs of the display module without increasing the number of column drive units, ensuring normal display of the display module.

[0034] Continue to refer Figure 1 The common terminals C1 of the pixel units 130 in the same column and the corresponding first connection lines L1 are distributed in a straight line.

[0035] Specifically, the common terminals C1 within the same column of pixel units 130 can be arranged along the column direction, and the first connecting lines L1 can be arranged as straight lines. This can avoid obstruction from other structures when the first connecting lines L1 are connected to the common terminals C1 during their extension. This can also avoid the need for punching holes and switching layers to connect the first connecting lines L1 to the common terminals C1, avoiding the need for an additional layer of board to form the first connecting lines L1. This simplifies the circuit design of the circuit connections within the display module and reduces the number of board layers required for the display module. Furthermore, by arranging the first connecting lines L1 in a straight line along the column direction, the spacing requirements between different pixel units 130 along the row direction can be reduced, facilitating a compact arrangement of the pixel units 130 and improving the resolution of the display module.

[0036] Continue to refer Figure 1 The display module further includes a second connection line L2, through which the second electrodes of the light-emitting devices D1 of the same light-emitting color in a row of pixel units 130 are connected; the second connection line L2 is arranged in a different layer from the pixel units 130.

[0037] Specifically, Figure 1 The figure exemplifies a pixel unit 130 including light-emitting devices D1 of three different colors, so that one pixel unit 130 corresponds to three second connection lines L2, each used to connect the second electrodes of the three light-emitting devices D1 of different colors in a row of pixel units 130. The second connection lines L2 extend in the row direction, which is different from the extension direction of the first connection lines L1. By arranging the second connection lines L2 and the pixel units 130 on different layers, not only can the circuit layout of the layer where the pixel units 130 are located be simplified, but also the phenomenon of intersecting short circuits between the first connection lines L1 and the second connection lines L2, which could cause abnormal driving of the pixel units 130, can be avoided.

[0038] On the basis of the above technical solutions, Figure 2 This is a schematic diagram of a partial main view structure of a display module provided by an embodiment of the present invention. Figure 2 As shown, the display module also includes a first substrate 101 and a second substrate 102 that are stacked; the first substrate 101 includes a first surface A and a second surface B that are oppositely arranged, and the second substrate 102 includes a third surface C and a fourth surface D that are oppositely arranged, the first surface A is arranged on the side of the second surface B away from the third surface C, and the fourth surface D is arranged on the side of the third surface C away from the second surface B; the row driving unit 110 and the column driving unit 120 are arranged on the first surface A, the second surface B also includes a signal connection line L3, the second connection line L2 is arranged on the third surface C, and the pixel unit 130 is arranged on the fourth surface D; the row driving unit 110 and the column driving unit 120 are connected to the signal connection line L3, and the signal connection line L3 is used to provide a driving signal to the row driving unit 110 and the column driving unit 120; the row driving unit 110 provides a first driving signal to the first electrode of a column of light-emitting devices D1 through the common terminal C1, and the column driving unit 120 provides a second driving signal to the second electrode of a row of light-emitting devices D1 through the second connection line L2.

[0039] Specifically, the signal connection line L3 can be a clock signal line for providing a clock signal to the row driver unit 110 and the column driver unit 120. The signal connection line L3 can include multiple signal connection lines L3, with the row driver unit 110 and the column driver unit 120 corresponding to different signal connection lines L3, respectively, to achieve independent control of the row driver unit 110 and the column driver unit 120. The row driver unit 110 provides a first drive signal to the first electrode of a column of light-emitting devices D1 via the common terminal C1, and the column driver unit 120 provides a second drive signal to the second electrode of a row of light-emitting devices D1 via the second connection line L2. With the first drive signal and the second drive signal being effective simultaneously, a light-emitting device D1 is controlled to emit light. Furthermore, by arranging the light-emitting device D1 of the pixel unit 130 and the common terminal C1 on the same substrate layer, the display module only requires two substrate layers to achieve normal drive of the pixel unit 130, thereby saving substrates and facilitating a simplified and thinner design of the display module.

[0040] Based on the above technical solutions, the pixel unit includes three light-emitting devices with different luminous colors, the column driving unit includes three column driving sub-units, and an output end of each column driving sub-unit is electrically connected to the second electrode of the light-emitting device of the same luminous color in a row of pixel units.

[0041] Specifically, each column driver subunit can be identical. For example, each column driver subunit can be a column driver chip of the same model. When a pixel unit includes three light-emitting devices with different luminous colors, the same pixel unit can correspond to three column driver subunits, each configured to drive the three light-emitting devices with different luminous colors in a row of pixel units, thereby meeting the driving requirements of the display module.

[0042] Based on the above technical solutions, the display module includes at least one column driving unit, and the at least one column driving unit includes multiple output ends. Each output end of the column driving unit is electrically connected to the second electrode of the light-emitting device of the same light-emitting color in a row of pixel units.

[0043] Specifically, when the column driver unit includes multiple output terminals, each output terminal can be electrically connected to the second electrode of a light-emitting device of the same luminous color in a row of pixel units, so that the column driver unit can drive light-emitting devices of the same luminous color in multiple rows of pixel units, reducing the number of column driver units. When the pixel units include light-emitting devices of three luminous colors and the column driver unit includes three column driver sub-units, each column driver sub-unit includes multiple output terminals, and the number of output terminals is equal. In this case, the second electrodes of the light-emitting devices of the same luminous color in each row of pixel units are connected in a row and then correspondingly connected to an output terminal of a column driver sub-unit, and so on, so that each column driver sub-unit drives light-emitting devices of the same luminous color in multiple rows of pixel units, reducing the number of column driver sub-units.

[0044] On the basis of the above technical solutions, the row driving unit includes a plurality of output terminals, and the number of columns of the pixel units is a multiple of the number of the output terminals of the row driving unit.

[0045] Specifically, the row driver unit may include multiple output terminals, each of which may be electrically connected to a common terminal of a column of pixel units, allowing the row driver unit to provide drive current for multiple columns of pixel units. When dividing the number of pixel columns within each display module, the number of pixel columns may be set as a multiple of the number of output terminals of the row driver unit. This allows the display module to set the number of row driver units based on the number of pixel columns, thereby meeting the needs of the display module while maximizing the utilization of the row driver units.

[0046] Figure 3 FIG1 is a partial structural diagram of another display module provided by an embodiment of the present invention. Figure 3 As shown, the row driving unit 110 includes at least two row driving sub-units 111 , and the same output terminal of each row driving sub-unit 110 is connected to the common terminal C1 of the same column of pixel units 130 .

[0047] Specifically, Figure 3The figure exemplarily shows that the row driving unit 110 includes two row driving sub-units 111. At least two row driving sub-units 111 are the same row driving chip. By setting the same output terminal of at least two row driving sub-units 111 to be connected to the common terminal C1 of the same column of pixel units 130, at least two row driving sub-units 111 are connected in parallel to provide driving current for the light-emitting device D1 of the same column of pixel units 130, thereby ensuring the driving capability of the row driving unit 110. For example, when the display module has 48 columns and 135 rows of pixel units and each row driving unit 110 has 8 channels, a total of 6 row driving units 110 are required. When each driving unit 110 includes two row driving sub-units 111, a total of 12 row driving sub-units 111 are required. In this case, the driving capability of the row driving unit 110 can be guaranteed, and the required number of row driving sub-units 111 can be reduced compared to the prior art, thereby reducing the number of driving units in the display module.

[0048] An embodiment of the present invention further provides a display panel, which includes the display module according to any embodiment of the present invention.

[0049] Specifically, the display panel may include multiple display modules so that the size of the display panel meets the requirements. Since the display panel includes the display module provided by any embodiment of the present invention, it has the beneficial effects of the display module provided by any embodiment of the present invention, which will not be repeated here.
