Description
Technical Field
The present invention relates to a holding element, an optical module and an optical device, and more particularly, to a back plate, a light source module and a display device.
Background
With the advancement of technology, the traditional paper book data has gradually advanced towards electronic technology. Because the electronic data is easy to store and carry, the searching is more convenient than the traditional paper book. Therefore, in the aspect of document processing, the conventional paper document data is gradually replaced by electronic data, and gradually evolves to use the electronic device to record data, so as to provide the user with the functions of recording memorandum, even drawing, and the like. For example, when a user is in a class or takes a meeting, the user can record important notes by using a display device (such as a notebook computer or a tablet computer device) with an electronic notebook function without using a conventional notebook.
Generally, a display device with electronic notebook function is configured with a stylus and a digitizer tablet and a backlight module cooperating therewith. The back plate of the backlight module is generally made of metal material and has larger rigidity, but because the signal of the digital handwriting board can be interfered by metal, the digital handwriting board can be placed between the back plate of the backlight module and the reflector plate when being assembled with the backlight module.
On the other hand, since the strength of the rubber frame in the backlight module is not as high as that of the metal material, when the display device is subjected to factory impact testing, the rubber frame is deformed by impact force, and then the impact force is likely to be transmitted to the cover body and the display layer of the backlight module, which may cause the display layer inside the backlight module to be broken. Therefore, in order to enhance the structural strength and reliability, the back plate of the backlight module needs to be a fully-wrapped structure to provide sufficient protection for the optical elements contained therein, thereby improving the reliability of the device.
However, the tablet is also covered by the back plate, so that after the assembly is completed, if the touch function of the tablet is found to be xor, and the tablet needs to be disassembled, the tablet needs to be disassembled to be taken out only by disassembling each component in the backlight module of the display device, which is very labor-consuming and material-consuming. However, if the digitizer tablet is to be easily replaced and the structural strength and reliability of the display device are both considered, it is necessary to design a plurality of structural components that are combined with the back plate and can be used for collision avoidance.
The background section is only used to help the understanding of the present invention, and therefore the disclosure in the background section may include some known techniques which are not known to those skilled in the art. The statements in the "background" section do not represent that matter or the problems which may be solved by one or more embodiments of the present invention, but are known or appreciated by those skilled in the art before filing the present application.

FIG. 2D is a schematic view of the optical device being mounted on and removed from the display device of FIG. 1A. Referring to fig. 1A to fig. 1C, in the present embodiment, the display device 300 includes a display layer 310 and a light source module 200, and the light source module 200 is used for providing an illumination beam to the display layer 310. For example, in the embodiment, the light source module 200 may be a side-in type backlight module, and the display layer 310 may be a liquid crystal display layer, such as a liquid crystal display panel, but the invention is not limited thereto.
Specifically, as shown in fig. 1C and fig. 2A, in the present embodiment, the light source module 200 includes at least one optical element OE and the back plate 100. More specifically, as shown in fig. 1B to fig. 2C, in the present embodiment, the back plate 100 includes a first supporting portion 110 and a second supporting portion 120. The first bearing part 110 has a first bottom 111. The second bearing part 120 has a second bottom 121. A step SP is formed between the first bottom 111 of the first carrying part 110 and the second bottom 121 of the second carrying part 120 to form an opening region OP. More specifically, as shown in fig. 1C, the light source module 200 includes a light source (not shown), a light guide plate 210, a rubber frame 220 and a cover 230. The light source is disposed at one side of the light guide plate 210. The rubber frame 220 is disposed around the light guide plate 210. The cover 230 covers the light guide plate 210 and further covers the display layer 310. In addition, at least one optical film FM is disposed between the light guide plate 210 and the display layer 310.
Further, as shown in fig. 1B and fig. 2A to fig. 2C, in the present embodiment, the back plate 100 further includes a first connecting portion 130 and a second connecting portion 140, the first supporting portion 110 has two first end portions 112 and a first side portion 113, and the second supporting portion 120 has two second end portions 122, a second side portion 123, a third side portion 124 and a fourth side portion 125. Specifically, as shown in fig. 2B, in the present embodiment, the first connecting portion 130 and the second connecting portion 140 are respectively used to connect two ends of the first bottom portion 111 and the second bottom portion 121. In more detail, as shown in fig. 2A and 2B, in the present embodiment, two first end portions 112 of the first supporting portion 110 respectively protrude from the first bottom portion 111 along the first direction D1 to respectively connect one end of the first connecting portion 130 and one end of the second connecting portion 140; the two second end portions 122 of the second bearing part 120 respectively protrude from the second bottom part 121 along the opposite direction of the first direction D1 to respectively connect the other end of the first connection part 130 with the other end of the second connection part 140. As shown in fig. 2A to 2C, in the present embodiment, the first bottom portion 111, the second bottom portion 121, the first connecting portion 130 and the second connecting portion 140 surround the opening region OP in the space, and the length of the first connecting portion 130 or the second connecting portion 140 is equal to the size of the step SP.
On the other hand, as shown in fig. 1B and fig. 1C, in the present embodiment, the first side portion 113 of the first carrying portion 110 and the fourth side portion 125 of the second carrying portion 120 are opposite to each other, the second side portion 123 of the second carrying portion 120 and the third side portion 124 of the second carrying portion 120 are opposite to each other, and the first side portion 113, the second side portion 123, the third side portion 124, the fourth side portion 125 and the second bottom portion 121 of the second carrying portion 120 form an accommodating space S. As shown in fig. 1C, the accommodating space S includes a first sub-accommodating space S1 and a second sub-accommodating space S2, and the first bottom 111 of the first carrying portion 110 defines a boundary plane IP of the first sub-accommodating space S1 and the second sub-accommodating space S2. More specifically, in the present embodiment, the first bottom 111 of the first carrying part 110 is substantially flush with the boundary plane IP of the first sub-accommodating space S1 and the second sub-accommodating space S2.
Further, as shown in fig. 1C, in the present embodiment, the first sub-receiving space S1 is used for receiving at least one optical element OE mounted on the back plate 100, and the second sub-receiving space S2 is used for receiving the light source (not shown), the light guide plate 210 and the rubber frame 220. For example, in the present embodiment, the at least one optical element OE includes a digital plate DG and/or a reflective element RE, and when the at least one optical element OE is mounted on the back plate 100, the at least one optical element OE (i.e., the digital plate DG and/or the reflective element RE) is located between the light guide plate 210 and the second bottom 121. For example, the digitizer DG may be, but not limited to, a handwriting pad device such as a resistive pressure sensor, a capacitive pressure sensor, an inductive pressure sensor, a thin film pressure sensor, etc. applying electromagnetic induction technology. When the at least one optical element OE includes the digital plate DG, the sensing layer of the digital plate DG faces the light guide plate 210, so that the display device 300 can provide touch and writing functions.
Therefore, when the external impact is applied, the first side 113, the second side 123, the third side 124 and the fourth side 125 of the back plate 100 are impacted first, so that most of the impact force can be absorbed by the first side 113, the second side 123, the third side 124 and the fourth side 125 of the back plate 100, and only a slight impact force is transmitted to the rubber frame 220. Since the impact force is weakened to a great extent, the display layer 310 is not excessively pressed, and thus the reliability of the light source module 200 and the display device 300 can be improved.
Further, as shown in fig. 1C, in the present embodiment, the plastic frame 220 has a first portion 221 and a second portion 222, the first portion 221 is disposed on the first carrying portion 110, the second portion 222 protrudes from the first carrying portion 110 and is located on the cover light guide plate 210, and further, the second portion 222 is located between the display layer 310 and the light guide plate 210. The first portion 221 of the bezel 220 may be adhered to the first bottom 111 and the first side portion 113, and the second portion 222 of the bezel 220 may be adhered to the display layer 310 and/or the light guide plate 210, so as to increase the structural strength. Thus, when the rubber frame 220 absorbs only the remaining impact force, the degree of deformation can be further reduced, and further the transmission of the impact force is reduced, so that the reliability of the light source module 200 and the display device 300 can be further improved.
On the other hand, as shown in fig. 1C, fig. 2A and fig. 2D, in the present embodiment, at least one optical element OE (including the digital board DG and/or the reflective element RE) can be mounted on or dismounted from the backplate 100 through the opening region OP formed by the step SP between the first carrying portion 110 and the second carrying portion 120. Specifically, as shown in fig. 1C, in the present embodiment, when the at least one optical element OE is mounted on the back plate 100, the first bottom portion 111 and the second bottom portion 121 are respectively located at two sides of the at least one optical element OE, and orthographic projections of the first bottom portion 111 and the second bottom portion 121 on the at least one optical element OE do not overlap with each other. Thus, when the function of at least one optical element OE (including the digital board DG and/or the reflective element RE) is xor, and the optical element OE needs to be removed, the optical element OE can be taken out and replaced with a functional optical element without removing the elements of the backlight module of the display device 300. In this way, the display device 300 and the light source module 200 enable at least one optical element OE (including the digital plate DG and/or the reflective element RE) to be mounted on and dismounted from the backplate 100 through the opening region OP formed by the step SP between the first carrying portion 110 and the second carrying portion 120, so that the convenience of replacing the optical elements therein is provided. In this embodiment, the display device 300 further includes a cover plate 230, wherein the cover plate 230 covers the display layer 310 and also covers the plastic frame 220, and is suitable for protecting the display layer 310. The cover plate 230 may be a cover glass and/or a touch panel, but is not limited thereto.
In addition, in the above-mentioned embodiment, the position of the opening region OP formed by the step SP between the first carrying portion 110 and the second carrying portion 120 is illustrated as being adjacent to one long side of the display region of the display device 300 and opening toward the long side, but the invention is not limited thereto. In other embodiments, the position of the opening region OP may be adjacent to any short side of the display region of the display device 300 and open towards the short side, so that the light source module 200 and the display device 300 can still achieve the aforementioned functions and advantages, which are not described herein again.
In summary, the embodiments of the invention have at least one of the following advantages or effects. In the embodiment of the invention, the display device and the light source module can absorb most of impact force generated during impact by the configuration of the back plate, so that the reliability of the display device can be improved. In addition, the display device and the light source module enable at least one optical element to be assembled and disassembled on the back plate through the opening region formed by the step difference between the first bearing part and the second bearing part, and have convenience for replacing the optical element. Therefore, the display device and the light source module can meet the requirements of both convenience and reliability by the configuration of the back plate with the opening region.
