Description

Technical Field

[0001] The present invention relates to a cholesterol display device, and more particularly to a cholesterol display module and a manufacturing method thereof and a cholesterol display device. The manufacturing method and innovative structure thereof can improve the existing production efficiency and cost. Background Art

[0002] The production method of traditional cholesterol display is relatively complicated. In addition to consuming more flexible circuit boards, which increases production costs, the flexible circuit boards will form a large volume and be difficult to assemble.

[0003] See also Figure 1 ,exist Figure 1 In the prior art, a plurality of driving ICs 6 are disposed on the glass substrate 2, and the first driving circuit 3 and the second driving circuit 5 are electrically coupled to the plurality of driving ICs 6 and are respectively fabricated on the flexible printed circuit board 7. Because there are a plurality of driving ICs 6, the flexible printed circuit board 7 needs to accommodate a plurality of first driving circuits 3 and a plurality of second driving circuits 5, so the required area of ​​the flexible printed circuit board 7 is relatively large. As shown in the figure, the flexible printed circuit board 7 can be divided into two blocks, the right block and the lower block. Each flexible printed circuit board 7 in each block requires an independent connector to assemble the printed circuit board, so there are two connectors in total, so that the materials and the time for installing and assembling the printed circuit board are both doubled that of a single one.

[0004] Therefore, in order to effectively reduce production costs and save production time and assembly space, the main purpose of the present invention is to provide a cholesterol display module and a production method thereof and a cholesterol display device to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a cholesterol display module and a manufacturing method thereof and a cholesterol display device, so as to facilitate assembly when producing the cholesterol display device and reduce the material and time costs required for production.

[0006] The invention relates to a cholesterol display module with a display area, and the display area has a plurality of cholesterol liquid crystals.

[0007] To achieve at least one of the above advantages or other advantages, an embodiment of the present invention provides a cholesterol display module including at least one glass substrate, a plurality of first driving circuits, an insulating layer, and a plurality of second driving circuits.

[0008] In at least one glass substrate, the glass substrate includes a display area substrate and a driving circuit area substrate. The display area substrate corresponds to the display area and is used to sandwich multiple cholesterol liquid crystals with other layers. The driving circuit area substrate is integrally extended from two adjacent sides of the display area substrate. That is, in the same glass substrate, the driving circuit area substrate and the display area are respectively located in different areas of the glass substrate. Therefore, from the viewing angle direction of viewing the display screen of the cholesterol display module, the display area and the driving circuit area will not overlap.

[0009] A plurality of first driving circuits are arranged on the driving circuit area substrate, and the first driving circuits can be metal lines. After the insulating layer is covered on the surface of the driving circuit area substrate between the plurality of first driving circuits and the plurality of first driving circuits, a conductive through hole is arranged in the insulating layer to transmit electric energy, and then a plurality of second driving circuits are arranged on the other side surface of the insulating layer different from the plurality of first driving circuits, and the second driving circuits can be transparent ITO lines for easy visual penetration. Because of the arrangement of the conductive through hole, electric energy can be transmitted from the metal line of the first driving circuit to the ITO line of part of the second driving circuit through the insulating layer.

[0010] The display area substrate and the driving circuit area substrate both contain metal circuits and ITO circuits, so they can be processed simultaneously in the manufacturing process, which can save processing time and improve efficiency. In addition, the display area substrate and the driving circuit area substrate are integrated glass substrates, and only the size of the glass substrate needs to be slightly increased when purchasing materials, which has little impact on the cost. Compared with the prior art that uses a glass substrate with a large-area flexible circuit board design, the flexible circuit board needs to be purchased from outside and has a considerable amount of feed cost. The present invention has the advantage of a single material and does not require secondary processing to increase costs.

[0011] Furthermore, the cholesterol display module further includes a plurality of driving ICs, which are disposed on the driving circuit area substrate and adjacent to the display area substrate, and each driving IC is electrically connected to an end of a first driving circuit and a second driving circuit.

[0012] Furthermore, the cholesterol display module only needs to include a small area and a small number of flexible circuit boards. Multiple first drive circuits and multiple second drive circuits will converge on the flexible circuit board, and the flexible circuit board is partially adjacent to the edge of the glass substrate. There is also an assembly circuit board under the cholesterol display module. After the multiple first drive circuits and multiple second drive circuits converge on the flexible circuit board, the flexible circuit board will turn to be plugged into the assembly circuit board with a connector. The volume of the flexible circuit board used in the present invention is much smaller than that of the flexible circuit board in the prior art. Therefore, in terms of production, the materials and production are cheaper and more convenient, and it is easy to miniaturize and standardize the flexible circuit board to save mold manufacturing costs, or even directly buy standard products instead to save production time.

[0013] There are generally two glass substrates in a cholesterol display module, and the aforementioned glass substrate may refer to a glass substrate located below a plurality of cholesterol liquid crystals. A combination structure of a plurality of first driving circuits, an insulating layer, and a plurality of second driving circuits may be disposed on the upper surface of the glass substrate. Therefore, after the ITO circuit and the metal circuit converge on the flexible circuit board, the flexible circuit board will need to be turned to be plugged into the assembled circuit board on the bottom surface of the glass substrate with a connector.

[0014] The present invention also relates to a cholesterol display device, which includes three cholesterol display modules and an assembled circuit board. The three cholesterol display modules are stacked, the cholesterol display module has a display area, and the display area has multiple cholesterol liquid crystals. The cholesterol display module includes at least one glass substrate, multiple first driving circuits, an insulating layer, multiple second driving circuits, and a flexible circuit board.

[0015] In at least one glass substrate, the glass substrate includes a display area substrate and a driving circuit area substrate. The display area substrate corresponds to the display area and is used to sandwich multiple cholesterol liquid crystals with other layers. The driving circuit area substrate is integrally extended from two adjacent sides of the display area substrate. That is, in the same glass substrate, the driving circuit area substrate and the display area are respectively located in different areas of the glass substrate. Therefore, from the viewing angle direction of viewing the display screen of the cholesterol display module, the display area and the driving circuit area will not overlap.

[0016] A plurality of first driving circuits are arranged on the driving circuit area substrate, and the first driving circuits can be metal lines. After the insulating layer is covered on the surface of the driving circuit area substrate between the plurality of first driving circuits and the plurality of first driving circuits, a conductive through hole is arranged in the insulating layer to transmit electric energy, and then a plurality of second driving circuits are arranged on the other side surface of the insulating layer different from the plurality of first driving circuits, and the second driving circuits can be transparent ITO lines for easy visual penetration. Because of the arrangement of the conductive through hole, electric energy can be transmitted from the metal line of the first driving circuit to the ITO line of part of the second driving circuit through the insulating layer.

[0017] Furthermore, the cholesterol display module only needs to include a small area and a small number of flexible circuit boards. A plurality of first driving circuits and a plurality of second driving circuits converge on the flexible circuit board, and a portion of the flexible circuit board is adjacent to the edge of the glass substrate. An assembly circuit board is provided below the cholesterol display module. After the plurality of first driving circuits and a plurality of second driving circuits converge on the flexible circuit board, the flexible circuit board is turned to be plugged into the assembly circuit board with a connector.

[0018] To further illustrate, when looking down at the display area of ​​the cholesterol display device, the three flexible circuit boards of the three cholesterol display modules can be located on the same side of the three glass substrates and are staggered, so the three connectors of the assembled circuit boards correspond to the three flexible circuit boards are arranged side by side.

[0019] In addition, when looking down at the display area of ​​the cholesterol display device, the three flexible circuit boards of the three cholesterol display modules can also be located on the same side of the three glass substrates and overlapped, so that the three connectors of the assembled circuit board correspond to the three flexible circuit boards in a stacked arrangement.

[0020] The present invention also relates to a method for manufacturing a cholesterol display module. The cholesterol display module includes a glass substrate and has a display area. The glass substrate includes a display area substrate and a drive circuit area substrate. The display area substrate corresponds to the display area. The drive circuit area substrate extends integrally from two adjacent sides of the display area substrate. The manufacturing method includes the following steps:

[0021] Step 1: Synchronously fabricate multiple metal circuits on the display area substrate and the drive circuit area substrate of the glass substrate, which undergo mask covering, exposure, development, etching, and cleaning processes.

[0022] Step 2: coating an insulating layer on the surface of the substrate in the driving circuit area between the plurality of metal lines and simultaneously reserving conductive through holes, wherein the process includes mask covering, exposure, development, etching, and cleaning.

[0023] Step 3: Synchronously manufacture multiple IT0 circuits, wherein part of the IT0 circuits of the multiple IT0 circuits correspond to and extend into the conductive through-holes to electrically contact part of the metal circuits corresponding to the conductive through-holes, so that the conductive through-holes connect the first driving circuit and the second driving circuit for conduction, which also undergoes processes such as covering with a mask, exposure, development, etching, and cleaning.

[0024] Furthermore, the preparation method may also include the following steps:

[0025] A plurality of driving ICs are disposed on the driving circuit area substrate adjacent to the display area substrate, and each driving IC is electrically connected to a metal line and an end of an ITO line.

[0026] A flexible circuit board is arranged adjacent to the side edge of the substrate in the driving circuit area, and a plurality of metal circuits and a plurality of ITO circuits are respectively converged on the flexible circuit board.

[0027] Therefore, the cholesterol display module and its manufacturing method and a cholesterol display device provided by the present invention can not only reduce the use of flexible circuit boards compared to the prior art, but the display area substrate and the driving circuit area substrate are both circuits made of the same material, so they can be operated at the same time, and the number of connectors can be saved. Therefore, the material cost and installation man-hours are halved compared to the prior art. Based on the above three reasons, the convenience of saving time and labor can be achieved, and the highest production capacity has been achieved.

[0057] The object of the present invention is to provide a cholesterol display module and a manufacturing method thereof and a cholesterol display device, so as to reduce the required material and time costs when producing the cholesterol display device.

[0058] See also Figure 2 And with Figure 3 , Figure 2 is a side cross-sectional view of a cholesterol display module 100 of the present invention, Figure 3 1 is a top view of a cholesterol display module 100 of the present invention. The cholesterol display module 100 has a display area 23 composed of a plurality of cholesterol liquid crystals 10. The cholesterol display module 100 shown in the figure includes two glass substrates 20, a plurality of first driving circuits 30, an insulating layer 40, a conductive through hole 42, a plurality of second driving circuits 50, a driving IC 60 and a flexible printed circuit board 70.

[0059] In the figure, two glass substrates 20 are shown. The lower glass substrate 20 includes a display area substrate 22 and a drive circuit area substrate 24. The display area substrate 22 corresponds to the display area 23 and sandwiches a plurality of cholesterol liquid crystals 10 with the upper glass substrate 20. Figure 3 As shown, the driving circuit area substrate 24 integrally extends from two adjacent sides of the display area substrate 22 , that is, the driving circuit area substrate 24 in the glass substrate 20 is not in the display area 23 , and the display area 23 and the driving circuit area do not overlap.

[0060] A plurality of first driving circuits 30 are disposed on the driving circuit area substrate 24, and the first driving circuits 30 may be metal circuits, which may be formed together with the metal circuits on the display area substrate 22 in the display area 23 in the manufacturing process. Then, after the insulating layer 40 is covered on the surface of the driving circuit area substrate 24 between the plurality of first driving circuits 30 and the plurality of first driving circuits 30, a conductive through hole 42 is provided in the insulating layer 40 for transmitting electric energy, and then a plurality of second driving circuits 50 are disposed on the upper surface of the insulating layer 40 and on the other side surface different from the plurality of first driving circuits 30, and the conductive material of part of the second driving circuits 50 may be poured into the conductive through hole 42, and the second driving circuits 50 may be transparent ITO circuits for easy visual penetration, which may be formed together with the ITO circuits in the display area 23 in the manufacturing process, and finally, the insulating material may be filled between the plurality of second driving circuits 50. Because of the provision of the conductive through hole 42, electric energy may be transmitted from the metal circuits of the first driving circuits 30 to the ITO circuits of part of the second driving circuits 50 through the insulating layer 40.

[0061] Furthermore, multiple driver ICs 60 are arranged on the driver circuit area substrate 24 and adjacent to the display area substrate 22. Each driver IC 60 is electrically connected to the ends of a first driver circuit 30 and a second driver circuit 50. Multiple first driver circuits 30 and multiple second driver circuits 50 are converged on the flexible circuit board 70. The flexible circuit board can be turned and connected to the assembled circuit board 80 on the back of the cholesterol display module 100 through a connector.

[0062] See also Figure 4 And with Figure 2 , Figure 4 2 is a partial enlarged cross-sectional view of the cholesterol display module 100 of the present invention. The display area substrate 22 and the drive circuit area substrate 24 both contain metal circuits and ITO circuits, so they have the advantage of being able to be processed simultaneously in the process, in addition to achieving the purpose of saving processing time, it can also improve production efficiency. In addition, the display area substrate 22 and the drive circuit area substrate 24 are both the same glass substrate 20. Compared with the design of the prior art using a glass substrate 20 with a soft board, it has the advantage of a single material and does not require secondary processing to increase costs.

[0063] In the cholesterol display module 100, two glass substrates 20 can sandwich a plurality of cholesterol liquid crystals 10 and be stacked at the upper and lower parts, and the combination structure of a plurality of first driving circuits 30, an insulating layer 40, and a plurality of second driving circuits 50 is sequentially arranged on the upper surface of the lower glass substrate 20, and the flexible circuit board 70 can be adjacent to or partially connected to the edge of the glass substrate 20, so as to facilitate the convergence of the plurality of first driving circuits 30 and the plurality of second driving circuits 50 on the flexible circuit board 70, and the flexible circuit board 70 is convenient to turn and plug the connector on the assembly circuit board 80 under the lower glass substrate 20. The volume of the flexible circuit board 70 is much smaller than that of the flexible circuit board 70 in the prior art, so in addition to saving process and material costs and being cheaper in production, the flexible circuit board 70 is small in volume and convenient for turning and assembly, and can be directly purchased as a standard product that saves mold costs.

[0064] See also Figure 5 And with Figure 3 , Figure 5 Schematic diagram of a cholesterol display device 100A of the present invention. The present invention also relates to a cholesterol display device 100A including three cholesterol display modules 100 and an assembled circuit board 80. The three cholesterol display modules 100 are stacked. The cholesterol display module 100 also has a display area 23 as described in the previous example. The display area 23 has a plurality of cholesterol liquid crystals 10. In the example, each cholesterol display module 100 includes two glass substrates 20, a plurality of first driving circuits 30, an insulating layer 40, a plurality of second driving circuits 50, and a flexible circuit board 70.

[0065] The glass substrate 20 includes a display area substrate 22 and a drive circuit area substrate 24. The display area substrate 22 corresponds to the display area 23. In the example, the lower glass substrate 20 and the upper glass substrate 20 sandwich a plurality of cholesterol liquid crystals 10 within the display area 23. The drive circuit area substrate 24 extends integrally from two adjacent sides of the display area substrate 22, which means that in the same glass substrate 20, the drive circuit area substrate 24 and the display area 23 are located in different areas of the glass substrate 20, so from the viewing angle direction of viewing the display screen of the cholesterol display module 100, the display area 23 and the drive circuit area will not overlap.

[0066] The multiple first driving circuits 30 will continue to transmit electrical energy to some of the multiple second driving circuits 50 through the conductive through holes 42 set in the insulating layer 40. The second driving circuits 50 are set on the other side surface of the insulating layer 40 different from the first driving circuits 30. The first driving circuits 30 can be metal circuits, while the second driving circuits 50 are transparent ITO circuits that are easy to visually penetrate.

[0067] The cholesterol display device 100A has a flexible circuit board 70 connected to the glass substrate 20, and an assembled circuit board 80 is provided on the bottom surface of the lowest cholesterol display module 100. The assembled circuit board 80 has three connectors to respectively connect the three flexible circuit boards 70 of the three cholesterol display modules 100. The flexible circuit boards 70 of the three cholesterol display modules 100 are respectively plugged and converged to the assembled circuit board 80 through the three connectors. That is, after the electric energy of each cholesterol display module 100 is converged to the flexible circuit board 70 through the ITO circuit and the metal circuit, the flexible circuit board 70 is respectively turned to be plugged into the assembled circuit board 80 below the lowest cholesterol display module 100 through the connector.

[0068] See also Figure 6 , Figure 6 1 is a top view of the first embodiment of the cholesterol display device 100A of the present invention. From the perspective of looking down at the display area 23 of the cholesterol display device 100A, the three flexible circuit boards 70 of the three cholesterol display modules 100 are located on the same side of the three glass substrates 20 and are staggered. The side can be any of the long and short sides of the cholesterol display device 100A. As shown in the legend, it is the lower side in the long direction in the figure. At this time, the three connectors of the assembly circuit board 80 corresponding to the three flexible circuit boards 70 are preferably arranged side by side. Such a staggered design can prevent the flexible circuit boards 70 from overlapping. The length of the flexible circuit board 70 from top to bottom can be that the top layer is greater than or equal to the middle layer, and the middle layer is greater than or equal to the bottom layer. When the three layers are equal, the same size of flexible circuit boards 70 can be used universally. Therefore, when the flexible circuit board 70 is to be connected to the assembly circuit board 80 at the bottom of the cholesterol display device 100A, no extra thickness will be generated, and only one size of flexible circuit board 70 needs to be prepared during production.

[0069] See also Figure 7 , Figure 7 It is a top view of the second embodiment of the cholesterol display device 100A of the present invention. Also from the perspective of looking down at the display area 23, the three flexible circuit boards 70 of the three cholesterol display modules 100 can also be located on the same side of the three glass substrates 20 but in an overlapping arrangement. This side can also be any side of the long side or the short side, and the three connectors of the assembly circuit board 80 corresponding to the three flexible circuit boards 70 are preferably stacked. In this design, the length of the topmost flexible circuit board 70 will be greater than that of the middle layer, and the middle layer will be greater than the bottom layer. Therefore, after the current is collected on the flexible circuit board 70, the three flexible circuit boards 70 need to be turned together to connect to the assembly circuit board 80 at the bottom of the cholesterol display device 100A. Because of the different lengths, the cholesterol display device 100A can also have a thinner thickness. Because it is an overlapping arrangement, the width of the flexible circuit board 70 that needs to be folded back is narrower, and the appearance is more beautiful.

[0070] See also Figure 8 , Figure 8 1 is a flow chart of a method for manufacturing a cholesterol display module 100 of the present invention. The present invention also relates to a method for manufacturing a cholesterol display module 100. The cholesterol display module 100 comprises a glass substrate 20 and has a display area 23. The glass substrate 20 comprises a display area substrate 22 and a drive circuit area substrate 24. The display area substrate 22 corresponds to the display area 23. The drive circuit area substrate 24 extends integrally from two adjacent sides of the display area substrate 22. The manufacturing method comprises the following steps:

[0071] Step 1 S01: Synchronously fabricate a plurality of metal circuits of the first driving circuit 30 on the display area substrate 22 and the driving circuit area substrate 24 of the glass substrate 20. This process step can also be fabricated simultaneously with the metal circuits of the display area substrate 22, which includes processes such as covering with a mask S0101, exposing S0102, developing S0103, etching S0104, and cleaning S0105.

[0072] Step 2 S02: coating an insulating layer 40 on the surface of the driving circuit area substrate 24 between the metal circuits of the first driving circuits 30 and the metal circuits, and reserving conductive through holes 42 corresponding to some of the metal circuits of the first driving circuits 30, wherein the process includes covering with a mask S0201, exposing S0202, developing S0203, etching S0204, and cleaning S0205.

[0073] Step four S03: Synchronously manufacture the IT0 circuits of the plurality of second driving circuits 50, wherein part of the IT0 circuits of the plurality of IT0 circuits correspond to and extend into the conductive through-holes 42 to electrically contact part of the metal circuits corresponding to the conductive through-holes 42, so that the conductive through-holes 42 connect the first driving circuit 30 and the second driving circuit 50 for conduction. This process step can also be manufactured synchronously with the IT0 circuits of the display area substrate 22, which also undergoes the processes of covering with a mask S0301, exposing S0302, developing S0303, etching S0304, and cleaning S0305.

[0074] Furthermore, the manufacturing method may also include the following steps: setting a plurality of driving ICs 60 on the driving circuit area substrate 24 adjacent to the display area substrate 22, wherein each driving IC 60 is electrically connected to the end of a metal circuit and an IT0 circuit, and further setting a flexible circuit board 70 adjacent to the side edge of the driving circuit area substrate 24, so that the plurality of metal circuits and IT0 circuits can be converged on the flexible circuit board 70.

[0075] In summary, the cholesterol display module 100 and its manufacturing method and a cholesterol display device 100A provided by the present invention can not only reduce the use of flexible circuit boards 70 compared with the prior art, but also the display area substrate 22 and the driving circuit area substrate 24 are circuits made of the same material, so they can be manufactured at the same time, and the number of connectors can be saved. Therefore, the material cost and installation man-hours are halved compared with the prior art. Based on the above three reasons, the convenience of saving time and labor can be achieved, and the highest production capacity can be achieved.
