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
Along with the progress of technology, traditional paper data has gradually advanced to electronics. Because the electronic data is easy to store and carry, the electronic data is more convenient to search than the traditional paper. Therefore, in terms of document processing, the conventional paper data has been gradually replaced by electronic data, and has gradually evolved to use electronic devices to record data, so as to provide functions such as recording memos and even drawing. For example, when a user takes a lesson or performs a meeting, the user can take important notes by carrying a display device (such as a notebook or tablet computer) with the function of an electronic notebook without using a conventional notebook.
Generally, a display device with an electronic notebook function is configured with a stylus, a digital writing pad cooperating with the stylus, and a backlight module. The back plate of the backlight module is generally made of metal material and has high rigidity, but because the signal of the digital handwriting board is interfered by metal, the digital handwriting board is placed between the back plate of the backlight module and the reflecting plate when the digital handwriting board is assembled with the backlight module.
On the other hand, since the strength of the plastic frame in the backlight module is not as high as that of the metal material, when the display device is subjected to the factory impact test, the plastic frame is likely to be deformed by the impact force, and then the impact force is likely to be guided to the cover body and the display layer of the backlight module, which will cause the display layer on the inner side of 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 of a fully-covered structure to provide sufficient protection for the optical element accommodated therein, thereby improving the reliability of the device.
However, the digital handwriting board is also covered by the back plate, so that when the touch function of the digital handwriting board is found to be exclusive or the digital handwriting board needs to be disassembled after the assembly is completed, all components in the backlight module of the display device need to be disassembled together to take out the digital handwriting board, and labor and materials are very consumed. However, if the digital handwriting board is to have the convenience of being replaceable and the structural strength and the reliability of the display device are both considered, a plurality of structural components combined with the back plate and used for anti-collision are required to be additionally designed, so that additional parts are added, the number of dies is increased, the production cost is increased, and market competition is not favored.
The background section is only for the purpose of aiding in the understanding of the present invention and thus the disclosure of the background section may include some techniques that do not form part of the knowledge of one of ordinary skill in the art. The disclosure of the "background" section is not intended to represent the subject matter or problem underlying one or more embodiments of the present invention, as it would be known or appreciated by one of ordinary skill in the art prior to the application of the present invention.

Fig. 2D is a schematic diagram of the optical element when attached to and detached from the display device of fig. 1A. Referring to fig. 1A to 1C, in the present embodiment, the display device 300 includes a display layer 310 and a light source module 200, wherein the light source module 200 is used for providing an illumination beam to the display layer 310. For example, in the present embodiment, the light source module 200 may be a side-in backlight module, and the display layer 310 may be a liquid crystal display layer, such as a liquid crystal display panel, but the present 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 a back plate 100. More specifically, as shown in fig. 1B to 2C, in the present embodiment, the back plate 100 includes a first carrying portion 110 and a second carrying portion 120. The first bearing portion 110 has a first bottom 111. The second bearing portion 120 has a second bottom 121. The first bottom 111 of the first bearing part 110 and the second bottom 121 of the second bearing part 120 have a step SP therebetween to form an opening area 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 plastic frame 220, and a cover 230. The light source is disposed at one side of the light guide plate 210. The glue 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 carrying portion 110 has two first end portions 112 and a first side portion 113, and the second carrying 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 connection portion 130 and the second connection portion 140 are respectively used to connect two ends of the first bottom 111 and the second bottom 121. In more detail, as shown in fig. 2A and 2B, in the present embodiment, two first ends 112 of the first bearing portion 110 respectively protrude from the first bottom 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 portion 120 respectively protrude from the second bottom portion 121 along the opposite direction of the first direction D1 to respectively connect the other end of the first connecting portion 130 with the other end of the second connecting portion 140. As such, as shown in fig. 2A to 2C, in the present embodiment, the first bottom 111, the second bottom 121, the first connection portion 130 and the second connection portion 140 surround the opening area OP in the space, and the length of the first connection portion 130 or the second connection portion 140 is the size of the step SP.
On the other hand, as shown in fig. 1B and 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 a receiving 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 bearing portion 110 defines a boundary plane IP of the first sub-accommodating space S1 and the second sub-accommodating space S2. In more detail, in the present embodiment, the first bottom 111 of the first bearing portion 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-accommodating space S1 is used for accommodating at least one optical element OE mounted on the back plate 100, and the second sub-accommodating space S2 is used for accommodating a light source (not shown), a light guide plate 210 and a glue 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 digital board DG may be, but not limited to, a writing board device using a resistive pressure sensor, a capacitive pressure sensor, an inductive pressure sensor, a thin film pressure sensor, etc. of electromagnetic induction technology. When the at least one optical element OE includes the digital board DG, the sensing layer of the digital board DG faces the light guide plate 210, so that the display device 300 can provide touch and writing functions.
In this way, when the back plate 100 is impacted by the outside, the first side 113, the second side 123, the third side 124 and the fourth side 125 of the back plate 100 are impacted, so that the first side 113, the second side 123, the third side 124 and the fourth side 125 of the back plate 100 absorb most of the impact force, and only a small amount of impact force is transmitted to the frame 220. Since the impact force is weakened much, the display layer 310 is not excessively pressed, and 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 glue frame 220 has a first portion 221 and a second portion 222, the first portion 221 is disposed on the first bearing portion 110, the second portion 222 protrudes from the first bearing 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 adhesive frame 220 may be adhered to the first bottom 111 and the first side 113, and the second portion 222 of the adhesive frame 220 may be adhered to the display layer 310 and/or the light guide plate 210 to increase structural strength. In this way, when the plastic frame 220 absorbs only residual impact force, the deformation degree can be further reduced, and the transmission of the impact force can be further 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, 2A and 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 and dismounted from the back plate 100 through the opening area OP formed by the step SP between the first bearing portion 110 and the second bearing portion 120. Specifically, as shown in fig. 1C, in the present embodiment, when at least one optical element OE is mounted on the back plate 100, the first bottom 111 and the second bottom 121 are respectively located at two sides of the at least one optical element OE, and the orthographic projections of the first bottom 111 and the second bottom 121 on the at least one optical element OE do not overlap each other. In this way, when the function of at least one optical element OE (including the digital board DG and/or the reflective element RE) is not needed to be disassembled, the optical element with good function can be removed and replaced without disassembling the elements in the backlight module of the display device 300. In this way, the display device 300 and the light source module 200 can be assembled and disassembled on the back plate 100 through the opening area OP formed by the step difference SP between the first bearing portion 110 and the second bearing portion 120, so as to facilitate the replacement of the optical elements therein. In this embodiment, the display device 300 further includes a cover 230, wherein the cover 230 covers the display layer 310 and also covers the glue frame 220, and is suitable for protecting the display layer 310. The cover 230 may be a cover glass and/or a touch panel, but is not limited thereto.
In the foregoing embodiment, the position of the opening area OP formed by the step SP between the first carrier 110 and the second carrier 120 is shown as being adjacent to one of the long sides of the display area of the display device 300 and opening toward the long side, but the present invention is not limited thereto. In other embodiments, the position of the opening area OP may be any short side of the display area adjacent to the display device 300 and open towards the short side, so that the light source module 200 and the display device 300 still achieve the above-mentioned functions and advantages, which are not described herein.
In summary, the embodiments of the present 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 the impact force generated during impact by the configuration of the back plate, so that the reliability of the display device can be improved. And, the display device and the light source module can be assembled and disassembled on the back plate through the opening area formed by the step difference between the first bearing part and the second bearing part, so that the convenience of replacing the optical element is realized. Therefore, the display device and the light source module can meet the requirements of convenience and reliability through the configuration of the back plate with the opening area.
