Abstract
Description
Technical Field
[0001] This invention relates to the field of liquid crystal writing film technology, and in particular to a liquid crystal writing film with auxiliary lines, a writing board, and a blackboard. Background Technology
[0002] For elementary school students or those practicing calligraphy, referring to certain auxiliary lines when writing, such as grid lines, Chinese pinyin auxiliary lines, and English four-line three-space auxiliary lines, is essential to help standardize writing. Alternatively, when creating musical notation, staff auxiliary lines are also needed to accurately identify musical notes.
[0003] However, the inventors discovered that most LCD writing tablets or blackboards on the market do not have any auxiliary lines in the writing area. Users do not have reference marks during the writing process, which is not conducive to the standardization and alignment of writing, and to a certain extent, limits the function and applicable users of LCD writing tablets or blackboards.
[0004] In existing technologies, a second display screen is set within the LCD screen, and different patterns or lines are pre-stored in the second display screen. Users can freely choose the pattern to be copied or the grid corresponding to the text to be written based on the patterns stored in the second display screen. This technology is generally implemented by creating an intaglio coating on the display screen surface, and the coating is relatively thick. It needs to be made on the display screen surface by certain technical means, which can easily lead to poor adhesion and peeling. When using it, users must write according to the intaglio graphic text, and each product has fixed graphic text, which cannot allow for free writing and doodling. The processing cost of this technology is generally high and the difficulty is relatively large.
[0005] In existing technologies, auxiliary lines are set on the writing area of the liquid crystal writing film by ink screen printing or inkjet printing to serve as an auxiliary reference. However, with repeated use, the auxiliary lines will wear out or fall off, affecting the performance. At the same time, the auxiliary lines will also cause the writing to be discontinuous, affecting the user experience. Moreover, the clarity of the auxiliary lines will also be affected when viewed from a distance. Summary of the Invention
[0006] In view of this, the present invention discloses a liquid crystal writing film with auxiliary lines, a writing board and a blackboard. The lines are drawn on the liquid crystal writing film by etching process, which can avoid the wear or fall off of the auxiliary lines and avoid the problem of discontinuous writing. Moreover, the processing cost is low.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A liquid crystal writing film with auxiliary lines includes: a first conductive layer, a liquid crystal layer, and a second conductive layer; a plurality of closed regions are etched on one of the conductive layers, the closed regions are spliced together to form auxiliary lines, and the auxiliary lines are combined to form a predetermined pattern; a predetermined distance is spaced between two adjacent closed regions.
[0009] In other embodiments, the following technical solutions are adopted:
[0010] A liquid crystal writing film with auxiliary lines includes: a first conductive layer, a liquid crystal layer, and a second conductive layer; several closed regions are etched on the first conductive layer and the second conductive layer respectively, and the closed regions are spliced together to form auxiliary lines; the auxiliary lines on the first conductive layer and the second conductive layer together form a predetermined pattern; and a predetermined distance is spaced between two adjacent closed regions.
[0011] The auxiliary lines are etched into the conductive layer inside the liquid crystal writing film in a closed area. The closed area can display the same color as the writing, so there is no visual experience of discontinuous writing when writing. In addition, since the closed area cannot be electrified, the color in the area will always be displayed once written and will not be erased. As a result, the pattern formed by the auxiliary lines is always displayed, which can help users to refer to the writing.
[0012] At the same time, when writing, you will not directly touch the guide lines, thus avoiding wear and tear on them.
[0013] In other embodiments, the following technical solutions are adopted:
[0014] A liquid crystal writing board includes the liquid crystal writing film with auxiliary lines described above.
[0015] or,
[0016] A liquid crystal blackboard includes the liquid crystal writing film with auxiliary lines described above.
[0017] In other embodiments, the following technical solutions are adopted:
[0018] A liquid crystal writing board includes: a substrate and a liquid crystal writing film disposed on the substrate; auxiliary lines are disposed on the substrate by means of ink screen printing, inkjet printing, laser printing, or laser etching, and the auxiliary lines are combined to form a predetermined pattern.
[0019] or,
[0020] A blackboard includes: a substrate and a liquid crystal writing film disposed on the substrate; on the substrate, auxiliary lines are disposed by means of ink screen printing, inkjet printing, laser printing, or laser etching, and the auxiliary lines are combined to form a predetermined pattern.
[0021] Using processes such as ink screen printing, inkjet printing, laser printing, and laser etching, the ink is applied to the substrate inside the LCD blackboard and writing board. During the writing process, there will be no visual experience of discontinuous handwriting, and the writing will not directly contact the guide lines, thus avoiding the problem of wear or detachment of the guide lines.
[0022] Compared with the prior art, the beneficial effects of the present invention are:
[0023] The auxiliary lines of this invention are etched onto the conductive layer inside the liquid crystal writing film using an etching process, or are set on the substrate inside the liquid crystal blackboard and writing board using processes such as ink screen printing, inkjet printing, laser printing, and laser etching. During the writing process, the auxiliary lines will not come into direct contact with the writing board, thus avoiding the problem of wear or detachment of the auxiliary lines.
[0024] The auxiliary lines of this invention are etched onto the conductive layer inside the liquid crystal writing film in a closed area manner. The closed area can display the same color as the writing, so there is no visual experience of discontinuous writing when writing. In addition, since the closed area cannot be electrified, the color in the area is always displayed, and thus the pattern composed of the auxiliary lines is always displayed, which can help users to use as an auxiliary reference when writing.
[0025] The form of the auxiliary lines in this invention does not affect the thickness and internal structure of the writing board, and the manufacturing cost is low. Attached Figure Description

[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0032] Example 1
[0033] In one or more embodiments, a liquid crystal writing film with auxiliary lines is disclosed, comprising: a first conductive layer, a liquid crystal layer and a second conductive layer; a plurality of closed regions 1 are etched on one of the conductive layers, the closed regions 1 are spliced together to form auxiliary lines 2, and the auxiliary lines 2 are combined to form a set pattern.
[0034] Specifically, the enclosed area 1 can be a rectangle, ellipse, circle, triangle, or other shape. The pattern it forms can be: a grid, a Chinese character grid, a rice-shaped grid, a rice-shaped grid with a back-and-forth pattern, a back-and-forth pattern, an English four-line three-space grid, a four-line pinyin grid, mathematical writing auxiliary lines, or musical staff auxiliary lines, or a combination of the above patterns; or other pattern forms that those skilled in the art can conceive of for auxiliary reference during writing.
[0035] Figure 1 The combination of four-line pinyin grid and rice-shaped grid is given. Of course, other combinations of patterns are also possible. Figure 1 In the middle, several closed areas 1 are pieced together to form a horizontal, vertical or diagonal line. These lines are all auxiliary lines 2. The desired pattern is formed by combining auxiliary lines 2.
[0036] A single closed regional structure such as Figure 2 As shown, the size of the closed area 1 is determined according to the area of the writing film and the number of patterns required; the shape of the closed area 1 can also be set according to the designer's requirements.
[0037] Reference Figure 1 A set distance is set between two adjacent closed regions 1, so that the conductive area inside the pattern formed by the auxiliary lines 2 can be energized by the spaced area, so that the writing in the area can be erased.
[0038] The auxiliary lines are etched into the conductive layer inside the liquid crystal writing film in a closed area. The closed area 1 can display the same color as the writing, so there will be no discontinuous writing experience when writing. In addition, since the closed area 1 cannot be powered, the color in this area is always displayed and cannot be erased. As a result, the pattern formed by the auxiliary lines is always displayed, which can help users to refer to the writing.
[0039] The auxiliary line 2 is etched onto the conductive layer inside the liquid crystal writing film using an etching process. During the writing process, the auxiliary line will not come into direct contact with the writing process, thus avoiding the problem of wear or detachment of the auxiliary line.
[0040] It should be noted that the liquid crystal writing film structure in this embodiment can be applied to liquid crystal writing films with one-click erasure, blackboards and writing boards, as well as liquid crystal writing films with partial erasure.
[0041] Through the structural improvements to the liquid crystal writing film in this embodiment, the functions of the liquid crystal writing film can be expanded, and the scope of application and the target audience can be broadened.
[0042] Example 2
[0043] In one or more embodiments, a liquid crystal writing film with auxiliary lines is disclosed, comprising: a first conductive layer, a liquid crystal layer, and a second conductive layer; a plurality of closed regions 1 are respectively etched on the first conductive layer and the second conductive layer, and the closed regions 1 are spliced together to form auxiliary lines 2; the auxiliary lines 2 on the first conductive layer and the second conductive layer together form a predetermined pattern; and a predetermined distance is spaced between two adjacent closed regions 1.
[0044] In this embodiment, several closed regions 1 are etched on two conductive layers respectively, and auxiliary lines 2 formed on the two conductive layers are superimposed and combined to form a set pattern. This can reduce the number of closed regions etched on each conductive layer, which is beneficial to reduce the difficulty of the process, and at the same time, it can make the pattern more delicate, more complex and more diverse.
[0045] The other structures and overall implementation principles are the same as in Embodiment 1, and will not be repeated here.
[0046] Example 3
[0047] In one or more embodiments, a liquid crystal writing board is disclosed, which employs a liquid crystal writing film with auxiliary lines as described in Embodiment 1 or Embodiment 2.
[0048] It should be noted that this writing board can be a one-click erasing writing board or a partial erasing writing board.
[0049] Of course, the above-described LCD writing board structure is also applicable to LCD blackboards or LCD drawing boards, etc., and will not be described in detail in this embodiment.
[0050] Example 4
[0051] In one or more embodiments, a liquid crystal writing board is disclosed, the writing board including a substrate and a liquid crystal writing film disposed on the substrate; on the substrate, auxiliary lines are disposed by means of ink screen printing, inkjet printing, laser printing or laser etching, and the auxiliary lines are combined to form a predetermined pattern.
[0052] The pattern can be: a square, a Chinese character grid, a rice-shaped grid, a rice-shaped grid with a back-and-forth pattern, a back-and-forth pattern, an English four-line three-space grid, a four-line pinyin grid, a mathematical writing auxiliary line or a five-line staff auxiliary line, or a combination of the above patterns; or other pattern forms that can be conceived by those skilled in the art for the purpose of providing auxiliary reference when writing.
[0053] In this embodiment, the auxiliary lines can be continuous lines.
[0054] In this embodiment, the structure of the liquid crystal writing board does not require modification of the liquid crystal writing film structure. It only requires setting the corresponding pattern on the substrate. The pattern can be displayed on the outermost layer of the writing board to serve as an auxiliary reference. At the same time, the auxiliary lines will not be worn or detached due to writing, and there will be no visual experience of discontinuous handwriting.
[0055] Of course, the structure and principle of the above-mentioned liquid crystal writing board are also applicable to liquid crystal blackboards or liquid crystal drawing boards, etc., and will not be described again in this embodiment.
[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
