Description

Light emitting module and display module

The invention relates to a light emitting module and a display module.

The large-screen display system can centrally display signals from a variety of different signal sources to meet the needs of users to display various shared information and comprehensive information in a large area. In a common method, a large-sized display panel is usually formed by splicing multiple smaller display panels. In the display area of each smaller display panel, the red, blue, and green light-emitting elements in the display area are usually arranged in an order and along a direction. In an ideal situation, these light emitting elements are arranged in a specific arrangement order. However, because there is no obvious mark on the general light-emitting element to indicate its light-emitting color, it is possible to arrange the light-emitting elements of the same light-emitting color together during the splicing process, and this will cause the same light-emitting color in some areas. The pitch of the light-emitting elements is small (for example, the blue light-emitting elements and the blue light-emitting elements are arranged together), and the pitch of the light-emitting elements with the same color in some areas is large. For example, if the preset color of the light emitting element is arranged in the order of red, green, blue, red, green, blue, etc., if the arrangement order is wrong, it may become red, green, Blue, blue, green, red... this situation. Therefore, when the user uses the above-mentioned large-size display panel, it will cause inconsistent color light emission, which further affects the display quality.

On the other hand, in each smaller display panel, there is usually a display area and a border area, and the display area is provided with display pixels and some traces, and the border area is used to set the driving circuit , Part of the wiring or the area of other electronic components, so the border area (or invalid display area/non-display area) usually cannot display the screen. After the splicing is completed, there will be invalid display areas between these smaller display panels, resulting in a discontinuity in the overall display image, which in turn affects the viewing quality.

The invention provides a light-emitting module, which makes the display module with the light-emitting module have good display quality, and the display module with the light-emitting module provides a seamless display screen.

The driving substrate DP further includes a power supply PS, a scan driver SD, and a data driver DD. In the following paragraphs, the above-mentioned components and the corresponding arrangement relationship will be described in detail.

The light-emitting module 100 can be controlled to emit light and can further display images according to the image data, so it can also be regarded as a sub-display module in the display module 200. Please refer to FIGS. 1 to 6, these light emitting modules 100 are located in the display area DR. The light emitting module 100 includes a carrier substrate 110, a plurality of light emitting elements 120, a module controller 130, and an alignment portion 140. Each element in the light emitting module 100 will be described in detail in the following paragraphs.

The carrier substrate 110 is a substrate for supporting various components in the light emitting module 100. 1 to 4, the carrier substrate 110 has a first surface S1, a second surface S2, and side surfaces SS1, SS2 connecting the first and second surfaces S1, S2. The first surface S1 is opposite to the second surface S2. The first surface S1 faces the display side DS. The second surface S2 then faces the back side BS. The carrier substrate 110 includes a circuit layer CL and a plurality of via holes H. The circuit layer CL is provided on the second surface S2. These via holes H penetrate the carrier substrate 110.

These light-emitting elements 120 refer to optical elements that themselves have a light-emitting function. Please refer to FIG. 1 to FIG. 3, the light-emitting elements 120 are disposed on the first surface S1 and are correspondingly disposed on the via holes H (as shown in FIG. 2 ). These light-emitting elements 120 include a plurality of light-emitting elements of different emission colors, and for example, include a plurality of red, green, and blue light-emitting elements R, G, and B. The red, green, and blue light-emitting elements R, G, and B are, for example, arranged on the first surface S1 in the order of light-emitting colors of blue, green, and red, but not limited thereto.

In other embodiments, the light emitting color of the light emitting element 120 may also be other different light emitting colors such as yellow, purple, white, etc. The present invention is not limited thereto. In addition, the arrangement order of the light-emitting elements 120 is not limited to the arrangement of blue, green, and red colors, and may also be different color arrangement orders of red, blue, and green; green, red, and blue; This is limited. In addition, in this embodiment, the number of light-emitting elements 120 included in each light-emitting module 100 is, for example, six. For example, in other embodiments, the number of light-emitting elements 120 may be less than six or greater than Six, the invention is not limited to this. Those of ordinary skill in the art can design the light-emitting color, the light-emitting color arrangement sequence, and the number of light-emitting elements 120 according to requirements, and the present invention is not limited thereto.

In this embodiment, the type of the light-emitting element 120 may be a light-emitting diode, a sub-millimeter light-emitting diode (Mini LED) or a micro light-emitting diode (Micro LED), an organic light-emitting diode (Organic Light Emitting Diode, OLED), wherein the size of the sub-millimeter light-emitting diode falls within the range of 100 microns to 200 microns, for example, and the size of the miniature light-emitting diode is, for example, the size of the micron level, and its size is, for example, less than 100 microns and In the range greater than 0 micrometers, the invention is not limited to this.

The module controller 130 drives these light-emitting elements 110 to emit light according to the image data from the scan driver SD and the data driver DD, and further causes the light-emitting module 100 to display an image screen. In this embodiment, the module controller 130 includes an integrated circuit (Integrated Circuit) with a small volume, which may also be referred to as a chiplet. 2 and 4, the module controller 130 is disposed on the second surface S2. The module controller 130 is electrically connected to the light-emitting elements 110, and is electrically connected to the light-emitting elements 110 through the via holes H and the circuit layer CL, for example. In addition, the module controller 130 is further provided with a bonding pad BP for bonding with the circuit.

The alignment part 140 is located only on the side SS1 of the carrier substrate 110. As shown in FIGS. 1 to 6, the state of the alignment part 140 included in the light emitting module 100 is, for example, a bump. Therefore, in the entire light emitting module 100, the outer contour formed by the alignment portion 140 and the carrier substrate 110 is asymmetrical. In detail, the so-called "outer profile asymmetry" in this paragraph can be seen in the following way: assuming that a reference axis RA1 whose axis is perpendicular to the normal vector of the first surface S1 passes through the center of the first surface S1, and, If the first surface S1 is viewed in a plan view (ie, in the direction opposite to the direction D3), it can be seen that the partial outer contour of the carrier substrate 110 on the left side of the reference axis RA1 is asymmetrical to the carrier substrate on the right side of the reference axis RA1 110 and the local outline of the alignment portion 140. In short, through the setting of the alignment portion 140, the light emitting module 100 can provide the user with visual asymmetry on the reference plane formed by the directions D1, D2. Part of the light-emitting element 120 (for example, the red light-emitting element R) is closer to the alignment portion 140, and part of the light-emitting element 120 (for example, the blue light-emitting element B) is farther from the alignment portion 140. Therefore, the user can determine the light emission color of the light emitting element 120 according to the position of the alignment portion 140, that is, the user can determine the light emission by the asymmetry of the outer contour of the alignment portion 140 and the carrier substrate 110 The emission color of the element 120. The alignment part 140 can also be regarded as a kind of mark for judging the light emitting color of the light emitting element 120.

Please refer to FIG. 5, the driving substrate DP includes a base BE and a plurality of signal lines SL. The base 112 has a plurality of positioning portions FP. The base BE has a bottom surface S3 and an inner surface S4, the bottom surface S3 is connected to the inner surface S4, and the inner surface S4 is, for example, stepped, but not limited thereto. The bottom surface S3 and the inner surface S4 define a corresponding positioning portion FP. In this embodiment, each positioning portion FP includes a groove GV. The groove GV includes a first groove GV1, a second groove GV2, and a third groove GV3. The first groove G1 is adjacent to the bottom surface S3. The second groove G2 is adjacent to the outside of the display module 200 compared to the first groove G1. The third groove G3 is located on one side of the second groove G2.

Referring again to FIG. 5, according to the above, the light emitting module 100 can be fitted into the base BE of the driving substrate DP through the positioning portion FP. When the light emitting module 100 is fitted into the driving substrate DP, the module controller 130 is embedded in the first groove GV1, the carrier substrate 110 is embedded in the second groove GV2, and the alignment portion 140 (bump state) Sample) is embedded in the third groove GV3, as shown in Figure 6 after assembly. In other words, the carrier substrate 110, the alignment portion 140, and the module controller 120 can be engaged with the corresponding positioning portion FP. Please refer to FIG. 6. After the assembly is completed, the carrier substrate 110 covers the module controller 130 and the signal line SL, and the light emitting elements 120 are exposed to the outside of the display module 200.

Please refer to FIG. 6 again. On another reference plane formed by the directions D1 and D3, the light-emitting module 100 of this embodiment can also provide asymmetry of the user's vision. In detail, it is assumed that another reference axis RA2 whose axis is parallel to the normal vector of the first surface S1 passes through the center of the first surface S1, and, as can be seen from FIG. 6: the carrier substrate 110 on the left side of the reference axis RA2 The local outer contour of the alignment portion 140 is asymmetrical to the local outer contour of the carrier substrate 110 on the right side of the reference axis RA2. In short, through the setting of the alignment part 140, the light emitting module 100 can provide the user's asymmetry on the reference plane formed by the directions D1, D3.

The power supply PS is an electronic component used to provide power to each component in the display module 200. The scan driver SD and the data driver DD can transmit control signals to these module controllers 130 through the signal line SL according to the image data. The module controllers 130 then cause the light emitting modules 100 to display image frames according to the image data. The power supply SP, the scan driver SD, and the data driver DD are disposed in the non-display area NDR, and are all electrically connected to the signal line SL of the driving substrate DP. Specifically, the power supply SP and the scan driver SD are disposed on one side of the non-display area NDR (for example, the left side in FIG. 1), and the data driver DD is disposed on the other side of the non-display area NDR (for example, As shown in the lower side of Figure 1). Referring to FIG. 5, the power supply SP and the scan driver SD power supply 120 are electrically connected to the module controllers 130 through a part of these signal lines SL (that is, the signal lines SL of this part serve as the power lines PL), and Used to provide electricity. The scan driver 130 is electrically connected to the module controllers 130 through a part of these signal lines (that is, the signal line SL of this part serves as the scan line SCL). The data driver 140 is electrically connected to the module controllers 130 through a part of these signal lines (that is, the signal line SL of this part serves as the data line DL).

The arrangement of the light emitting module 100 in the display area DR will be described in detail in the following paragraphs.

In this embodiment, the positioning portions FP are arranged in a matrix MX. Since the light emitting modules 100 are fitted into the positioning portions FP, the light emitting modules 100 are also arranged in a matrix MX. The alignment portion 140 in each light emitting module 100 protrudes toward the direction D1.

As described above, in the light emitting module 100 and the display module 200 of this embodiment, the alignment portion 140 is located on the side SS1 of the carrier substrate 110 to make the outer contours formed by the alignment portion 140 and the carrier substrate 110 asymmetrical, and these The light emitting element 120 and the alignment part 140 have different distances. Therefore, the user can determine the arrangement of the light-emitting colors according to the distance between the light-emitting element 120 and the alignment portion 140.

For example, in the light emitting module 100, the red light emitting element R is closer to the alignment portion 140, the blue light emitting element B is farther from the alignment portion 140a, and the green light emitting element G is located at the red and blue light emitting elements Between R and G, the user can determine the arrangement of the light emission colors as blue, green, and red according to the distance between the light emitting element 120 and the alignment portion 140.

According to the above configuration, when the user embeds the light-emitting module 100 in the driving substrate DP, although there is no obvious mark on the light-emitting element 120 to indicate its light-emitting color, the user can still use the alignment portion 140 and the light-emitting element The distance between 120 is used to determine the light-emitting color of the corresponding light-emitting element 120, whereby the arrangement order of the light-emitting colors in the corresponding light-emitting module 100 can be known. In this way, during the embedding process, it can be ensured that the light-emitting elements 120 are arranged in a predetermined light-emitting color arrangement order (for example, blue, green, red, blue, green, red...), and the arrangement order is greatly avoided Set condition. Therefore, the display module 200 of this embodiment can avoid inconsistent light-emitting positions of colored light, and has good display quality.

Next, in the light-emitting module 100 and the display module 200 of this embodiment, the light-emitting elements 120 are disposed on the first surface S1, and the module controller 130 is disposed on the second surface S2 facing the back side BS to conduct The hole H penetrates the carrier substrate 110. The module controller 130 and the related wiring layer (circuit layer CL) are buried between the carrier substrate 110 and the driving substrate DP. In other words, the light emitting module 100 of this embodiment integrates the display function on the first surface S1 of the carrier substrate 110, and integrates the control function and the signal transmission function on the second surface S2 of the carrier substrate 110.

Therefore, when the user views the display screen of the display module 200, since the wiring and the control elements that do not have the display function are not located on the first surface S1, the light-emitting elements 120 can be arranged on the first surface in a tighter arrangement On S1, the display resolution can be increased.

At the same time, the first surface S1 does not need to be provided with wiring or control elements, and the invalid display area is omitted. After these light-emitting modules 100 are fitted into the driving substrate DP, the entire display area DR can effectively display the screen, avoiding the situation of the invalid display area mentioned in the conventional technology, so the display module 200 of this embodiment can Provide seamless display screen (that is, continuous display screen), and has good display quality.

Please refer to FIG. 6 again. In this embodiment, since the first surface S1 and the surface SE of the substrate BE exposed to the outside of the display module 200 are substantially aligned, this design is beneficial to the subsequent module packaging process.

7 is a schematic cross-sectional view of a light emitting module according to another embodiment of the invention.

The functions and connection relationships of the components have been described in the above paragraphs, and will not be repeated here. Since the arrangement order (such as blue, green, and red) of the light-emitting colors of these light-emitting elements 120 has been preset, the user can intuitively embed the carrier substrate 110 provided with a plurality of light-emitting elements 120 in corresponding positions The FP greatly avoids the misalignment of the emission color arrangement order. Therefore, the light emitting module 100' according to the embodiment of the present invention can provide the user with the above convenience.
