Description
Technical Field
[0001] The utility model relates to a liquid crystal handwriting board, in particular to an interesting liquid crystal handwriting board and a handwriting pen. Background Art
[0002] Cholesteric liquid crystal is one of many liquid crystal materials. It has a unique spiral structure, which produces reflection of external ambient light. It is widely used in the reflective field, one of which is the liquid crystal writing tablet. Cholesteric liquid crystal writing tablets display in the form of reflection of external light, and do not require a backlight source. At the same time, applying pressure can change the state of liquid crystal molecules to achieve reflection of external ambient light. When clearing, a momentary voltage is applied to flip the liquid crystal molecules to achieve clearing. Therefore, this product is dust-free and ink-free. When clearing the screen, a momentary voltage is applied, and no voltage is required to maintain the display. It is very energy-saving and environmentally friendly.
[0003] In order to enhance the fun of existing LCD writing tablets, one way is to make the material transparent so that it can be used for copying; another way is to turn a monochrome writing tablet into a multi-color one; and some also add an LCD screen to enhance the fun by combining the content on the screen with sound.
[0004] Although there are transparent LCD tablets, strip-shaped color LCD tablets, and ordinary black-bottom LCD tablets, in principle, they are all based on the fact that the liquid crystal molecules become P state when writing, and the reflection of ambient light produces color. This has a big disadvantage: in the absence of ambient light, the reflection cannot be seen, making it unusable. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide an interesting liquid crystal handwriting board and a handwriting pen, which solves the problem that the reflection cannot be seen in the absence of ambient light, resulting in the inability to use the handwriting board.

[0007] A base plate, which forms the main structural basis of the tablet;
[0008] At least one functional film selected from a fluorescent film or a temperature-sensitive film, the functional film being arranged above the bottom plate and used for changing visual feedback;
[0009] A transparent liquid crystal handwriting film, arranged above the functional film, has an adjustable transparency range for realizing the writing function and maintaining clear visibility under different lighting conditions.
[0010] As a preferred technical solution, grooves are formed between the functional film and the bottom plate, and the gap between the grooves is 0.5 mm-20 mm.
[0011] As a preferred technical solution, grooves are formed between the transparent liquid crystal handwriting film and the bottom plate, and the gap between the grooves is 0.5mm-20mm.

[0013] As a preferred technical solution, the transparency of the transparent liquid crystal handwriting film is set at 80%-20%, so that the transparency of the transparent liquid crystal handwriting film can be adjusted according to different usage environments and visual effect requirements.
[0014] As a preferred technical solution, the thickness of the functional film is between 0.1 mm and 3 mm, and the material of the functional film is a plastic material with a certain elasticity to ensure feedback and recovery performance under the action of handwriting pressure.
[0015] The utility model discloses an interesting liquid crystal handwriting board, comprising:
[0016] A base plate, which forms the main structural basis of the tablet;
[0017] At least one functional film selected from a fluorescent film or a temperature-sensitive film, the functional film being arranged below the bottom plate and used for changing visual feedback;
[0018] A liquid crystal handwriting film is arranged below the base plate and has an adjustable transparency range.
[0019] As a preferred technical solution, the transparency of the liquid crystal handwriting film is set at 80%-0%, and when light does not pass through, it is a black liquid crystal handwriting film.
[0020] As a preferred technical solution, grooves are formed between the functional film and the base plate, and the gap between the grooves is 0.5mm-20mm. Grooves are formed between the liquid crystal handwriting film and the base plate, and the gap between the grooves is 0.5mm-20mm. The thickness of the functional film is between 0.1mm and 3mm. The material of the functional film is a plastic material with a certain elasticity to ensure feedback and recovery performance under handwriting pressure.
[0021] The utility model discloses a stylus pen, which is used in conjunction with an interesting liquid crystal handwriting board, and comprises:
[0022] A pen tip assembly for writing on a transparent liquid crystal handwriting film;

[0024] Wherein, the light-emitting component is detachable to adapt to the needs and usage scenarios of different users.
[0025] The beneficial effects of the utility model are:
[0026] 1. When the functional film of the utility model is a fluorescent film, it can be combined with the light-emitting component of the pen head at night to achieve writing in complete darkness. When the pen head emits light and shines on the functional film (fluorescent film), the brightness and duration of the fluorescent film are different at different irradiation times. Generally speaking, the higher the light intensity and the longer the time, the higher the fluorescence brightness of the functional film (fluorescent film) and the longer the duration. In a low-light environment, you can simultaneously see the writing content of the handwriting board and feel the fluorescent light, which greatly enhances interactivity and fun.

[0037] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0038] like Figure 1 — Figure 2 As shown, the utility model is an interesting liquid crystal handwriting board, comprising:
[0039] A base plate 1, which constitutes the main structural basis of the handwriting tablet and plays a role of supporting the entire product through the base plate 1;
[0040] At least one functional film 2, selected from a fluorescent film or a temperature-sensitive film, the functional film 2 is arranged above the bottom plate 1 and is used to change the visual feedback;
[0041] A transparent liquid crystal handwriting film 3 is arranged above the functional film 2 and has an adjustable transparency range, so as to realize the writing function and remain clearly visible under different lighting conditions.
[0042] There are grooves formed between the functional film 2 and the bottom plate 1, and the gap between the grooves is 0.5mm-20mm;
[0043] Among them, a groove is formed between the transparent liquid crystal handwriting film 3 and the bottom plate 1, and the gap between the grooves is 0.5mm-20mm;
[0044] On the one hand, the gap is retained to facilitate production and processing, increase the tolerance of the process, and prevent stacking between layers, which may cause poor assembly; on the other hand, it increases the reliability of the product and prevents deformation of the overall structure or cracking between layers due to thermal expansion and contraction, which may affect functional use.
[0045] The functional film 2 is fixed around by adhesive tape or attached to the bottom plate 1 with adhesive on the entire surface to prevent sliding.
[0046] In addition, the transparency of the transparent liquid crystal handwriting film 3 is set at 80%-20%, so that the transparency of the transparent liquid crystal handwriting film 3 can be adjusted according to different use environments and visual effect requirements.
[0047] In addition, the thickness of the functional film 2 is between 0.1 mm and 3 mm, and the material of the functional film 2 is a plastic material with a certain elasticity to ensure feedback and recovery performance under the handwriting pressure; the liquid crystal handwriting film is on top of the functional film 2. Because the liquid crystal handwriting film senses pressure, if the functional film 2 is thicker, it will cause a sinking and soft feeling when writing, which greatly affects the writing experience.
[0048] When the functional film 2 is a fluorescent film (light-storing film), the transparent film handwriting film can be used for normal writing during the day, and has the same function as an ordinary LCD handwriting board; at night or when the light is relatively dark, the light on the light pen shines on the LCD handwriting board, and the light shines on the functional film 2 (fluorescent film) through the transparent LCD handwriting film 3. When the light is removed, the irradiated part emits a fluorescent effect, and the fluorescence then passes through the transparent handwriting film to the human eye, realizing the function of light writing. The time of light writing depends on the intensity and time of the light exposure and the fluorescent formula components inside the functional film 2; this handwriting board can be used as an ordinary handwriting board for writing, and can also be used for light writing, which greatly enhances the playability.
[0049] When the functional film 2 is a temperature-sensitive film, the handwriting board can be written normally, and its function is the same as that of an ordinary liquid crystal handwriting board; when an object of a certain temperature is placed on the liquid crystal film, the temperature is transferred to the functional film 2 through heat, and the functional film 2 reflects light of different colors, and the transparent handwriting film can be used to create on the underlying pattern. Such a temperature-sensitive film is set to a certain color (usually black) at a certain temperature. When the critical temperature is exceeded, different colors at different temperatures or different brightness at different temperatures are displayed. After the heat evaporates naturally, it returns to the original color. Such a handwriting board greatly increases the fun. Previously, there was only pressure sensing, but now both temperature and pressure sensing changes have been realized.
[0050] like Figure 3-Figure 4 The utility model is an interesting liquid crystal handwriting board, comprising:
[0051] A base plate 1, forming the main structural basis of the handwriting tablet;
[0052] At least one functional film 2, selected from a fluorescent film or a temperature-sensitive film, the functional film 2 is arranged below the bottom plate 1 and is used to change the visual feedback;
[0053] A liquid crystal handwriting film is arranged below the bottom plate 1 and has an adjustable transparency range.
[0054] Among them, the transparency of the liquid crystal handwriting film is set at 80%-0%. When light does not pass through, it is a black liquid crystal handwriting film.
[0055] In addition, grooves are formed between the functional film 2 and the base plate 1, and the gaps between the grooves are 0.5mm-20mm. Grooves are formed between the liquid crystal handwriting film and the base plate 1, and the gaps between the grooves are 0.5mm-20mm. The gaps are retained for the convenience of production and processing, to increase the tolerance of the process, and to prevent stacking between layers and poor assembly. On the other hand, the reliability of the product is increased to prevent deformation of the overall structure or cracking between layers due to thermal expansion and contraction, thereby affecting functional use. The thickness of the functional film 2 is between 0.1mm and 3mm, and the material of the functional film 2 is a plastic material with a certain elasticity to ensure feedback and recovery performance under handwriting pressure.
[0056] Ordinary fluorescent functional film 2 (also known as light-storing film) usually has a background color, which will more or less affect the display effect of the transparent film liquid crystal handwriting film, so the functional film 2 is placed on the back of the bottom shell. In this way, the front of the board can be written normally with the liquid crystal handwriting film (at this time the handwriting film can be a conventional black-bottom handwriting film with a transmittance of 0), which will not affect the writing effect of the handwriting film, and the back can be written with light, which greatly enhances the playability.
[0057] When the functional film 2 is a temperature-sensitive film, in order to prevent the transparent handwriting film or the temperature-sensitive film from overlapping and affecting the experience, the temperature-sensitive film is placed under the bottom shell. The handwriting film can be set to have a transmittance of 0, and for normal writing, it has the same function as an ordinary liquid crystal handwriting film; when temperature sensing is needed, it is placed on the back, and the temperature is transferred to the functional film 2, which reflects light of different colors. Such a temperature-sensitive film is set to a color (usually black) at a certain temperature. When the critical temperature is exceeded, different temperatures and different colors or different temperatures display different brightness. After the heat evaporates naturally, it returns to the original color. Such a handwriting board greatly increases the fun. Previously, there was only pressure sensing, but now both temperature and pressure sensing changes have been achieved.
[0058] like Figure 5-Figure 6 As shown, the utility model is a stylus pen used in conjunction with an interesting liquid crystal handwriting board, comprising:
[0059] A pen tip assembly 4, used for writing on the transparent liquid crystal handwriting film 3;
[0060] An illumination component 5 integrated with a light-emitting component, the light-emitting component can emit a spectrum including ultraviolet light, which is used to activate the fluorescent effect of the fluorescent film or increase the temperature sensing reaction speed of the temperature-sensitive film;
[0061] The lighting component 5 is detachable to meet the needs and usage scenarios of different users; for example, the lighting component is a pen cover that can be put on the pen tip component 4;
[0062] In addition, the plastic tip of the pen tip assembly 4 can apply tip pressure to the liquid crystal handwriting film; the lighting component 5 has a button, and the light-emitting component can be turned on and off by the button; the wavelength of light emitted by the light-emitting component must include the ultraviolet part, such as emitting purple light or white light; the lighting component 5 contains structures such as batteries, and the light switch can be controlled by the button on the lighting component 5.
[0063] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
