[0052] In this way, the display module of the embodiment of the present application is provided with light-emitting units of different sizes for different areas.

[0071] In this way, considering that Micro LED is an inorganic light-emitting diode and will not be oxidized, its corresponding light-emitting unit layer does not need to be provided with an encapsulation layer, and the flatness of the display module can be achieved by setting the thickness of the flexible filling layer 408, for example, Figure 1 As shown, the thickness of the flexible filling layer 408 , the filter layer 402 and the touch metal layer 403 in the first area is equal to the thickness of the filter layer 402 , the touch metal layer 403 , the encapsulation layer 404 and the pixel definition layer 405 in the second area.

[0072] Optional, such as Figure 3 and Figure 4 As shown, the Micro LED includes:

[0073] A light-emitting layer 503, a first semiconductor layer 502 and a second semiconductor layer 504 respectively disposed on both sides of the light-emitting layer 503, a first electrode layer 501 disposed on a side of the first semiconductor layer 502 away from the light-emitting layer 503, and a second electrode layer 505 disposed on a side of the second semiconductor layer 504 away from the light-emitting layer 503;

The Micro LED can be mounted upright or inverted in the driving layer. The length of the Micro LED can be 0.1um to 100um, preferably 25um; the width can be 0.1um to 100um, preferably 10um.

[0078] Optional, such as Figure 4 As shown, the driving layer further includes a planarization (PLN) layer, and the PLN layer is an organic layer.

[0079] In addition, in this embodiment, the first region includes at least one first portion 305 arranged along a first direction and at least one second portion 306 arranged along a second direction, wherein the first direction is a length direction of the substrate 407 and the second direction is a width direction of the substrate 407 .

[0080] That is, the first portion 305 is arranged along the first direction, and the second portion 306 is arranged along the first direction, for example, Figure 2 As shown, a first portion 305 is provided along the first direction in the first region, and the first portion 305 is divided into a first sub-region 305a and a second sub-region 305b; a second portion 306 is provided along the second direction, and the second portion 306 includes a third sub-region 306a and a fourth sub-region 306b.

[0081] In this way, the display module of this embodiment can be folded left and right, or up and down, for example, it can be folded left and right first, then up and down; or it can be folded up and down first, then left and right. Of course, the folding can be inward or outward, and the specific folding method can be set in multiple directions according to the needs.

[0082] Of course, if the first area includes multiple first parts and multiple second parts, the multiple first parts are all arranged along the first direction, and the intervals can be the first preset value; the multiple second parts are all arranged along the second direction, and the intervals can be the second preset value.

[0083] In this embodiment, the first direction in the drawing is the X direction, the second direction is the Y direction, and the third direction (the thickness direction of the substrate) is the Z direction.

[0085] The plurality of first light emitting units 409 in the same second portion 306 are connected to different data lines in a one-to-one correspondence and to the same gate line.

[0086] That is, the first light-emitting units 409 in the same first part 305 share a data line but have a separate gate line; the first light-emitting units 409 in the same second part 306 share a gate line but have a separate data line.

[0087] Optionally, in this embodiment, in the first direction, the adjacent first light emitting units 409 and the second light emitting units 410 are connected to the same data line and are connected to different gate lines in a one-to-one correspondence;

[0088] In the second direction, the adjacent first light emitting units 409 and the second light emitting units 410 are connected to different data lines in a one-to-one correspondence and are connected to the same gate line.

[0089] That is, the first light-emitting unit 409 and the second light-emitting unit 410 adjacent to each other in the first direction share a data line but have a separate gate line; the first light-emitting unit 409 and the second light-emitting unit 410 adjacent to each other in the second direction share a gate line but have a separate data line.

[0090] For example, Figure 5In the electronic device, the display integrated circuit (IC), i.e., the display IC103, controls the data signal of the display module through the first data line 801, the second data line 802, and the third data line 803, and controls the gate signal of the display module through the first gate line 701, the second gate line 702, and the third gate line 703. The three first light-emitting units (P2) in the first part 305 share the second data line 802, but are respectively connected to the first gate line 701, the second gate line 702, and the third gate line 703; the three first light-emitting units (P2) in the second part 306 share the second gate line 702, but are respectively connected to the first data line 801, the second data line 802, and the third data line 803. Furthermore, the first light-emitting unit on the leftmost side of the second portion 306 shares the first data line 801 with the two second light-emitting units (P1) adjacent to each other in the first direction, but are respectively connected to the first gate line 701, the second gate line 702, and the third gate line 703; the first light-emitting unit on the rightmost side of the second portion 306 shares the third data line 803 with the two second light-emitting units (P1) adjacent to each other in the first direction, but are respectively connected to the first gate line 701, the second gate line 702, and the third gate line 703. The first light-emitting unit on the top of the first portion 305 shares the first gate line 701 with the two second light-emitting units (P1) adjacent to each other in the second direction, but are respectively connected to the first data line 801, the second data line 802, and the third data line 803; the first light-emitting unit on the bottom of the first portion 305 shares the third gate line 703 with the two second light-emitting units (P1) adjacent to each other in the second direction, but are respectively connected to the first data line 801, the second data line 802, and the third data line 803.

[0091] The data line is also called the Vdata line, and the data signal used to transmit is the display brightness data signal of the first light-emitting unit and the second light-emitting unit. The display IC 103 can generate the data signal and control the voltage of the data signal. The edge area 700 of the display module is provided with a gate driving area to provide gate signals for the first light-emitting unit and the second light-emitting unit.

[0092] Optionally, the embodiment further includes:

[0093] A driving circuit is provided for the first light emitting unit and the second light emitting unit respectively.

[0094] That is, the display module is provided with a first driving circuit for the first light-emitting unit and a second driving circuit for the second light-emitting unit. In this way, the first light-emitting unit and the second light-emitting unit can have independent driving circuits respectively, and the display IC103 controls the timing and signal value of the data signal and the gate signal, and the first light-emitting unit and the second light-emitting unit can be controlled separately. For example, when the half screen is folded for display, the left half screen can be controlled to display and the pixels of the right half screen can be turned off according to the number of columns to be displayed; when the full screen is displayed, the first light-emitting unit and the second light-emitting unit of the full screen are both turned on for display.

[0095] Moreover, considering that the luminous brightness of the first light-emitting unit and the second light-emitting unit is different, the brightness unevenness of the first light-emitting unit and the second light-emitting unit can be eliminated (de-mura) before leaving the factory: the brightness calibration value of the first light-emitting unit is written into the display IC to ensure that the brightness of the first light-emitting unit and the second light-emitting unit can be kept uniform. In addition, at least two brightness calibration values ​​of the first light-emitting unit can be set, so that in a specific scene, such as when high brightness is required, another brightness calibration value is called to achieve high brightness display of the local first light-emitting unit. Optionally, the brightness of the high brightness display of the first light-emitting unit is three times the brightness of the second light-emitting unit.

[0096] The first driving circuit and the second driving circuit may be a 7T1C (7 transistors and 1 capacitor) integrated circuit or an 8T1C (8 transistors and 1 capacitor) integrated circuit. For example, the first driving circuit of the first light emitting unit 409 may be: Figure 6 The 7T1C integrated circuit shown.

[0097] Optionally, in this embodiment, if Figure 7-Figure 10 As shown, the overlapping area 300 of the first part 305 and the second part 306 is provided with a gap 400 that at least partially penetrates the substrate 407 and the light-emitting unit layer.

[0098] In this way, by partially hollowing out the display module, the bending curvature that can be sustained is increased, ensuring higher display flatness and better display effects, thereby achieving a lighter, thinner and larger display screen.

[0099] Of course, in addition to the overlap region 300, as Figure 2 As shown, a gap that at least partially penetrates the substrate 407 and the light-emitting unit layer may be provided in the non-overlapping first sub-region 305a, the second sub-region 305b, the third sub-region 306a, and the fourth sub-region 306b.

[0100] Optionally, the width of the gap 400 is equal to the distance between two sub-pixels, so as to reduce the influence of the gap 400 on the display effect.

[0101] Of course, the width of the gap 400 can be set to 1 um to 1000 um according to the requirements, and the best is the distance between two sub-pixels, such as 25 um.

[0102] Optional, such as Figure 8 As shown, the gap 400 extends from the cover plate to the base plate.

[0103] Optional, such as Fig. 9 As shown, the gap 400 extends from the cover plate to the driving layer.

[0104] Optional, such as Fig.10 As shown, the gap 400 extends from the flexible filling layer to the substrate.

[0105] Of course, the gap may penetrate one or more layers of the display module, and each layer may have one or more gaps to achieve a better folding effect.

[0106] Optionally, the penetration of the gap 400 is set to 1 um to 10 mm according to requirements, preferably set to 2 mm, so as to reduce the overall impact on the display.

[0107] Optional, such as Figure 2 As shown, in this embodiment, the second area is divided into a third part 301, a fourth part 302, a fifth part 303, and a sixth part 304 by the first part 305 and the second part 306, and,

[0108] In the first state of the display module, the projections of the third portion 301 , the fourth portion 302 , the fifth portion 303 , and the sixth portion 304 overlap.

[0109] In this way, Fig.17 and 18 As shown, after being folded left and right once and folded up and down once, the display module 200 reaches the first state, and the projections of the third part 301, the fourth part 302, the fifth part 303 and the sixth part 304 can overlap.

[0110] It should be noted that, in this embodiment, the inorganic layer can be a layer or multilayer structure of silicon oxide, silicon dioxide, silicon nitride, silicon oxynitride, aluminum oxide or zirconium dioxide; the organic layer can be a layer or multilayer structure of organic matter or polymer such as PI and resin; the metal layer can be a layer or multilayer structure of metals such as titanium, aluminum, titanium, molybdenum, silver, and copper.

[0111] In summary, the display module of the embodiment of the present application has higher bending resistance, which prolongs the service life of the display module; and can be folded up and down and left and right at the same time.

[0112] like Figures 11 to 18As shown, the embodiment of the present application further provides an electronic device, comprising the display module 200 as described above;

[0113] A main body 100 connected to the display module 200;

[0114] The display module 200 is connected to the main body 100 by a rotating shaft 101 and rotates around the main body 100 to form a preset angle.

[0115] in, Fig.11 is a front view of the display module 200 of the electronic device, Fig.12 It is a schematic back view of the unfolded display module 200 of the electronic device.

[0116] In this way, Figures 13 to 16 As shown, the user can form a certain angle between the display module 200 and the main body 100 through the rotating shaft, and reserve operating space to fold the display module 200 to achieve the following Fig.17 and Fig.18 The first state shown is completely folded to achieve minimum volume storage.

[0117] In summary, the electronic device of the embodiment of the present application has higher bending resistance by assembling the display module as described above, thereby extending the service life of the electronic device; and it can be folded up and down as well as left and right to meet the needs of users.
