Description

Technical Field

[0001] This invention relates to a light-emitting module and a display device. Background Technology

[0002] Micro-LED touch panels typically utilize photoresist material to encapsulate micro-LEDs, with a spacer placed on top of the photoresist. The spacer's material differs from the photoresist material used to encapsulate the micro-LEDs, resulting in poor elastic recovery of the touch panel. Furthermore, due to the different stress responses and elastic recovery characteristics of the photoresist material and the spacer, the touch panel requires a longer recovery time under stress, leading to poor linearity performance. Summary of the Invention

[0003] This invention provides a light-emitting module and a display device, which have good elastic recovery and can provide a good touch experience.

[0004] According to an embodiment of the present invention, a light-emitting module is provided, including a circuit board, a plurality of light-emitting elements, and a filling layer. The light-emitting elements are disposed on the circuit board. The filling layer includes an integrally formed covering portion and a supporting portion, wherein the covering portion covers and directly contacts at least one side of each light-emitting element, and the distance between the top surface of the supporting portion and the circuit board is greater than the distance between the top surface of each light-emitting element and the circuit board.

[0005] In one embodiment of the above-mentioned light-emitting module, the covering portion does not cover the top surface of each of the light-emitting elements.

[0006] In one embodiment of the above-described light-emitting module, the covering portion completely surrounds each of the light-emitting elements.

[0007] In one embodiment of the above-mentioned light-emitting module, the covering portion covers and directly contacts the top surface of each of the light-emitting elements.

[0008] In one embodiment of the above-mentioned light-emitting module, the supporting portion does not overlap the top surface of the covering portion.

[0009] In one embodiment of the above-mentioned light-emitting module, an upper substrate is further included, and the support portion abuts against the upper substrate.

[0010] According to one embodiment of the present invention, a display device is provided, including the above-described light-emitting module.

[0011] Based on the above, the light-emitting module provided in this embodiment of the invention is provided with a filling layer, which includes an integrally formed covering portion and a supporting portion. When a display device equipped with this light-emitting module is used as a touch panel, the touch panel requires a shorter recovery time under stress and exhibits better linearity performance.

[0012] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings. Attached Figure Description

[0027] Reference Figure 1 This diagram illustrates a light-emitting module according to a first embodiment of the present invention.

[0028] The light-emitting module 1 includes a circuit board 10, an upper substrate 20, an encapsulant 103, a plurality of light-emitting elements 200, and a filler layer 100. These light-emitting elements 200 are disposed on the circuit board 10. The light-emitting elements 200 can be, for example, micro-light-emitting diodes. It should be noted that, although... Figure 1 Only three light-emitting elements 200 are shown, but the light-emitting module 1 provided according to the embodiments of the present invention is not limited to containing three light-emitting elements 200, and the number of light-emitting elements 200 can be any positive integer.

[0029] The filling layer 100 can be implemented using a light-transmitting photoresist material and includes an integrally formed covering portion 101 and a support portion 102, wherein the support portion 102 abuts against the upper substrate 20 and does not overlap the top surface 101T of the covering portion 101. The covering portion 101 completely covers and directly contacts each light-emitting element 200, and the distance H2 between the top surface of the support portion 102 and the circuit board 10 is greater than the distance H1 between the top surface of each light-emitting element 200 and the circuit board 10. In some embodiments, the light-emitting module 1 can be configured in a display device.

[0030] Reference Figure 2 The diagram illustrates a comparative example of a light-emitting module. In this comparative example, the filling layer 100A of the light-emitting module 1A includes a covering portion 101A and a support portion 102A, wherein the covering portion 101A and the support portion 102A are not integrally formed, and the material of the covering portion 101A is different from that of the support portion 102A. When a display device equipped with the light-emitting module 1A is used as a touch panel, the non-integral nature of the covering portion 101A and the support portion 102A results in poor elastic recovery of the touch panel. Furthermore, due to the different materials of the covering portion 101A and the support portion 102A, their stress response and elastic recovery differ, causing the filling layer 100A to rebound twice after a touch event, resulting in a long rebound time. Because the panel requires a long recovery time under stress, and panel deformation leads to changes in signal distribution, it easily results in poor linearity performance of the panel.

[0031] Conversely, please refer to the following again. Figure 1 When the display device equipped with the light-emitting module 1 is used as a touch panel, since the covering portion 101 and the supporting portion 102 are integrally formed, the touch panel can have good elastic recovery. In addition, since the covering portion 101 and the supporting portion 102 are made of the same material, the filling layer 100 has a single stress response and a single elastic recovery, the touch panel requires a shorter recovery time under stress, and its linearity performance is better.

[0032] It should also be noted that the covering part 101 of the light-emitting module 1 covers and directly contacts the top surface of each light-emitting element 200, and completely surrounds each light-emitting element 200. This can avoid the situation of poor contact of the pins of each light-emitting element 200 and effectively avoid the problem of dark spots.

[0033] To fully illustrate the various embodiments of the present invention, other embodiments will be described below. It must be noted that the following embodiments use the component reference numerals and some content from the foregoing embodiments, with the same reference numerals indicating the same or similar components, and descriptions of identical technical content omitted. For explanations of the omitted parts, please refer to the foregoing embodiments; these will not be repeated in the following embodiments.

[0034] Reference Figure 3 This shows a schematic diagram of a light-emitting module according to a second embodiment of the present invention.

[0035] The light-emitting module 2 includes a circuit board 10, an upper substrate 20, an encapsulating adhesive 103, multiple light-emitting elements 200, and a filler layer 100. These light-emitting elements 200 are disposed on the circuit board 10. It should be noted that, although... Figure 3 Only three light-emitting elements 200 are shown, but the light-emitting module 2 provided according to the embodiments of the present invention is not limited to containing three light-emitting elements 200, and the number of light-emitting elements 200 can be any positive integer.

[0036] The filling layer 100 includes an integrally formed covering portion 101 and a supporting portion 102. The covering portion 101 covers and directly contacts at least one side of each light-emitting element 200. The supporting portion 102 abuts against the upper substrate 20, and the distance H2 between the top surface of the supporting portion 102 and the circuit board 10 is greater than the distance H1 between the top surface of each light-emitting element 200 and the circuit board 10. In some embodiments, the covering portion 101 may completely surround each light-emitting element 200. In this embodiment, the covering portion 101 does not cover the top surface of each light-emitting element 200, which can improve the electrical efficiency of the light-emitting module 2 and increase the overall brightness.

[0037] In summary, the light-emitting module provided in this embodiment of the invention has a filling layer, which includes an integrally formed covering portion and a supporting portion. When a display device equipped with this light-emitting module is used as a touch panel, the touch panel requires a shorter recovery time under stress and exhibits better linearity performance.
