Description

Spacer element of crimped glass substrate

The present invention relates to a spacer member that is sandwiched between a crimped glass substrate.

Glass substrates having a thickness of less than 150 microns are referred to as "ultra-thin glass substrates" which have better optical properties (e.g., transparency) and flexibility. Therefore, "ultra-thin glass substrates" have various applications such as electronic paper, flexible solar cells, touch panels, and organic light-emitting diode display panels.

Since the "ultra-thin glass substrate" has flexibility, the process of "ultra-thin glass substrate" generally adopts a roll-to-roll process. In a roll-to-roll process, glass substrates of different locations are curled together. In particular, a portion on the inner side in the radial direction of the glass substrate is in contact with a portion on the outer side in the radial direction of the glass substrate. This will cause the inner part to absorb the outer part. Therefore, when the glass substrate is taken out from the reel, the glass substrate is easily broken due to the adsorption of the inner portion and the outer portion. In addition, the electronic components placed on the glass substrate may be broken or damaged.

An embodiment of the invention provides a spacer element for a crimped glass substrate, Used to be sandwiched on a crimped glass substrate. The glass substrate includes at least one active region, a plurality of spaced regions, and two edge regions. A plurality of spaced regions and two edge regions define an active region. The spacer element of the crimped glass substrate includes two trailing edge elements and a plurality of bridging elements. Two towing edge elements correspond to two edge regions, and two towing edge elements are respectively connected at two ends of each bridge element, and the plurality of bridge elements correspond to a plurality of interval regions.

Anyone familiar with the relevant technology can easily understand the purpose and advantages of this proposal. The following examples further illustrate the views of this proposal in detail, but do not limit the scope of this proposal by any point of view.

First, please refer to FIGS. 1A to 1E. 1A is a schematic view of a gap-curled glass substrate according to a first embodiment of the present disclosure. 1B is a partial top plan view of the glass substrate wrapped in the region of the box B1 of FIG. 1A. Figure 1C is a partial top plan view of the spacer element of the crimped glass substrate encased in the region of the box B1 of Figure 1A. Figure 1D shows the spacer element of the crimped glass substrate wrapped in the area of the box B1 of Figure 1C sandwiched as in Figure 1B. A partial top view of a glass substrate. Figure 1E is a cross-sectional view of Figure 1D at the cutting line 1E-1E. In one embodiment, the glass substrate has a surface roughness (Ra) of less than 0.5 nanometers (nm) or a surface roughness (Rpv) of less than 20 nanometers (nm). The spacer elements of the crimped glass substrate are used to be sandwiched on a crimped glass substrate to improve the above problems.

The glass substrate 10 has a first surface F1 and a second surface F2 with respect to the first surface F1. The glass substrate 10 includes at least one active region 11, a plurality of spaced regions 12, and two edge regions 13. In this embodiment, the active region 11, the plurality of spacer regions 12, and the two edge regions 13 are all located on the first surface F1 of the glass substrate 10. The thickness of the glass substrate 10 is less than 150 microns and the glass substrate 10 is flexible. Therefore, the glass substrate 10 can be manufactured using a roll-to-roll process. However, in the roll-to-roll process of the glass substrate 10, the first surface F1 of the inner region (along the radial direction) of the glass substrate 10 is adsorbed on the second surface F2 of the outer region (along the radial direction), that is, facing First surface F1.

The active area 11 is the working area of the glass substrate 10. For example, electronic components such as circuits, sensors or liquid crystal cells may be disposed in the active region 11 of the glass substrate 10. In other words, the electronic component is not disposed in the spacer region 12 or the edge region 13.

The spacer element 20 of the crimped glass substrate is adapted to be sandwiched between the crimped glass substrate 10. The spacer element 20 of the crimped glass substrate comprises two tow side elements 21 and a plurality of bridging elements 22. Four bridging elements 22 are depicted in Figures 1B and 1C. However, the number of bridging elements 22 of the present disclosure is not limited.

The two trailing edge members 21 are connected to each end of each bridge member 22. Two tow side elements 21 and a plurality of bridging elements 22 define at least one hollow zone The domains 23, i.e., the two trailing edge members 21 and the plurality of bridging members 22 define an opening.

The trailing edge member 21 corresponds to the two edge regions 13 such that when the spacer elements 20 of the crimped glass substrate are stacked with the glass substrate 10, the edge regions 13 are disposed between the trailing edge members 21. The plurality of bridging elements 22 correspond to a plurality of spaced regions 12, and the width W1 of the bridging elements 22 is narrower than or equal to the width W2 of the spaced regions 12. Therefore, when the spacer element 20 of the crimped glass substrate is stacked with the glass substrate 10, a plurality of bridging elements 22 are disposed between the plurality of spacer regions 12. The hollow region 23 corresponds to the active region 11 and the area of the hollow region 23 is greater than or equal to the area of the active region 11. Therefore, when the spacer elements 20 of the crimped glass substrate are stacked between the curled glass substrates 10, the active regions 11 are disposed between the hollow regions 23. Therefore, when the spacer elements 20 of the crimped glass substrate are stacked between the curled glass substrates 10 (for the glass substrates spaced apart from each other), the edge regions 13 are disposed between the trailing edge members 21 and the bridging members 22 are disposed between the spacer regions 12 . Moreover, the active area 11 is disposed within the hollow area 23. Therefore, the active region 11 of the first surface F1 in the inner region (along the radial direction) of the glass substrate 10 does not contact the second surface F2 of the outer region (along the radial direction) of the glass substrate 10, so the active region 11 does not The second surface F2 of the glass substrate 10 is adsorbed. Further, the first surface F1 in the inner region (along the radial direction) of the glass substrate 10 is not adsorbed to the second surface F2 of the outer region (along the radial direction) of the glass substrate 10. When the curled glass substrate is unfolded, the glass substrate is not damaged, and the electronic components disposed on the glass substrate are not damaged or damaged.

In this implementation, the trailing edge member 21 is formed on the same member as the plurality of bridging members 22. For example, the trailing edge element 21 may be a plate-like structure, but the disclosure is not limited thereto. The tow side element 21 and the plurality of bridging elements 22 can be made of plastic (such as poly It is made of olefinic terephthalate, polyethylene naphthalate, polyimide, paper or metal foil, but the invention is not limited thereto. In other embodiments, the material of the trailing edge element 21 is different than the material of the plurality of bridging elements 22.

Referring to FIG. 1D, the width L1 of the spacer element 20 of the crimped glass substrate is greater than the width L2 of the glass substrate 10, but the invention is not limited thereto. Please refer to FIG. 1F. FIG. 1F is a partial top plan view showing the spacer element of the crimped glass substrate sandwiched on a curled glass substrate according to the second embodiment of the present disclosure. In this embodiment, the width L1 of the spacer member 20' of the rolled glass substrate is smaller than the width L2 of the glass substrate 10. In this embodiment, when the spacer elements 20' of the crimped glass substrate are stacked between the curled glass substrates 10, the trailing edge members 21 are disposed in the edge regions 13.

Please refer to Figures 2A-2D. 2A is a partial top plan view showing a spacer element of a crimped glass substrate according to a third embodiment of the present disclosure. 2B is a partial top plan view of a glass substrate according to a third embodiment of the present disclosure. 2C is a partial top plan view showing the spacer element of the rolled glass substrate of FIG. 2A sandwiched between the glass substrates. Figure 2D is a cross-sectional view of Figure 2C at the cutting line 2D-2D. In this embodiment, the spacer element 20a of the crimped glass substrate includes two trailing edge elements 21, a plurality of bridging elements 22, and at least one interconnecting element 24. The interconnecting element 24 connects two adjacent bridging elements 22. One interconnecting element 24 and four bridging elements 22 are illustrated in Figures 2A and 2C. Thus, the interconnecting element 24, the bridging element 22 and the two trailing edge elements 21 define four hollow regions 23a.

The glass substrate 10a includes at least one active region 11, a plurality of first compartment regions 12, two edge regions 13, and two second compartment regions 14. The first compartment area 12, the edge area 13 and the two second compartment areas 14 define an active area 11.

The two trailing edge elements 21 correspond to two edge regions 13. The bridging element 22 corresponds to the first spacing region 12, and the hollow region 23a of the glass substrate 10 corresponds to the two active regions 11. Interconnect element 24 corresponds to second compartment area 14. As shown in FIG. 2C, when the spacer elements 20a of the crimped glass substrate are stacked between the curled glass substrates 10 (similar to being sandwiched on the curled glass substrate 10a), each of the four active regions 11 has an active region 11 Corresponding to the hollow region 23a. Therefore, the active region 11 of the first surface F1 in the inner region (along the radial direction) of the glass substrate 10a does not contact the second surface F2 of the outer region (along the radial direction) of the glass substrate 10a, so the active region 11 does not The second surface F2 of the glass substrate 10a is adsorbed.

Please refer to FIG. 3. FIG. 3 is a partial top view of the spacer element of the crimped glass substrate according to the fourth embodiment of the present disclosure. In this embodiment, each of the two trailing edge members 21b has a plurality of through holes 210. These plurality of through holes 210 correspond to the teeth of the sprocket (not shown), so that it is very convenient to manipulate the spacer member 20b of the curled glass substrate in the roll-to-roll process.

Please refer to FIGS. 4A and 4B. 4A is a partial top plan view showing the spacer element of the crimped glass substrate of the fourth embodiment of the present invention sandwiched between a crimped glass substrate. Figure 4B is a cross-sectional view of Figure 4A at the cutting line 4B-4B. In this embodiment, the spacer element 20c of the crimped glass substrate includes two trailing edge elements 21c, and a plurality of bridging elements 22c. Each bridging element 22c has a first sleeve 221c at one end of the bridging element 22c and a second sleeve 222c at the other end of the bridging element 22c. The other trailing edge member 21c passes through the second sleeve 222c. For example, the trailing edge element 21c may be an iron wire, but the invention is not limited thereto. In this embodiment, when the spacer of the glass substrate is crimped When the member 20c is stacked between the curled glass substrates 10, the glass substrate 10 is supported by the first sleeve 221c and the second sleeve 222c so that the distance between the two glass substrates 10 can be maintained at a distance D. The pitch D corresponds to the thickness of the glass substrate 10. In other words, the height of the pitch D is greater than or equal to the thickness of the glass substrate 10.

Finally, please refer to Figure 5. 5 is a partial schematic view showing the spacer component of the crimped glass substrate of FIG. 1C sandwiched between the roll-to-roll process of the glass substrate of FIG. 1B. Figure 5 illustrates how the spacer elements of a crimped glass substrate can be applied in a roll-to-roll process. In Figure 5, a machine 9 is in a roll-to-roll process for making a crimped glass substrate. As shown in FIG. 5, the spacer element 20 of the crimped glass substrate can be used to space the glass substrate 10. How to extract and insert the spacer element 20 of the crimped glass substrate into the glass substrate 10 will be described below. In FIG. 5, the guide reel 70 is used to guide the spacer element 20 of the glass substrate 10 and/or the crimped glass substrate.

In this embodiment, the trailing edge member (not shown) of the spacer member 20 of the crimped glass substrate is sandwiched by a carrier (not shown), but the disclosure is not limited thereto. The carrier is used to secure the spacer element 20 of the crimped glass substrate in the machine table 9.

When the glass substrate 10 is withdrawn from the first reel 30 and moved along the first direction D1, the spacer elements 20 of the crimped glass substrate are stacked at different portions of the curled glass substrate 10, and are oriented toward the second reel along the second direction D2. 40 moves. As a result, the spacer element 20 and the glass substrate 10 of the crimped glass substrate are separated and the glass substrate 10 is taken out.

When the glass substrate 10 is loaded into the third reel 50 along the third direction D3, the spacer element 20 of the curled glass substrate moves toward the fourth reel 60 along the fourth direction D4. As a result, the spacer element 20 of the crimped glass substrate and the glass substrate 10 are wound together, and the spacer elements 20 of the crimped glass substrate are stacked on different portions of the curled glass substrate 10, and the glass substrate 10 is loaded.

In the case B2, different processes can be applied to the glass substrate 10. For example, a process such as grinding, polishing, cleaning a glass substrate, or depositing an adhesion layer and/or a component such as an organic component may be applied to the glass substrate 10.

According to the spacer element of the crimped glass substrate disclosed in the present invention, when the spacer element of the crimped glass substrate is sandwiched on the curled glass substrate, the trailing edge member corresponds to the edge region, the bridging member is disposed in the spacing region, and the active region is also disposed in the hollow region. Therefore, the active area does not contact or adhere to the second surface of the outer region of the glass substrate. Further, the first surface of the inner region of the glass substrate is not attached to the second surface of the outer region of the glass substrate. Therefore, it is very convenient to separate the curled glass substrate, and the glass substrate or the active region is not damaged during the separation.

In other embodiments, the spacer elements of the crimped glass substrate further comprise at least one interconnecting element. The number of hollow regions is determined by the change in the number of interconnecting elements. Thus, the user can employ an appropriate number of interconnecting elements with a suitable number of hollow regions such that the spacer glass substrate has a corresponding number of active regions.

In other embodiments, the trailing edge element further has a plurality of through holes corresponding to the teeth of the sprocket (not shown), so that in the roll-to-roll process, it is very convenient to manipulate the spacer elements of the crimped glass substrate.

In other embodiments, each bridging element has a first sleeve at one end of the bridging element and a second sleeve at the other end of the bridging element. a tow edge The element passes through the first sleeve and the other tow edge element passes through the second sleeve. Therefore, when the spacer elements of the crimped glass substrate are stacked at different portions between the curled glass substrates, a pitch corresponding to the thickness of the glass substrate is maintained by the sleeve.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
