Referring to fig. 1 to 3, a writing instrument 100 according to an embodiment of the present application includes a writing board 10 and a writing control pen 20. Tablet 10 includes writing area 12, writing area 12 including a media layer 126, and media layer 126 changing a display attribute based on a change in a target parameter. Writing control pen 20 includes a tip 23 and a control device 21 for controlling a target parameter of medium layer 126 via tip 23.

In the writing apparatus 100 of the above embodiment, the control device 21 controls the target parameter of the medium layer 126 through the pen tip 23, so that the medium layer 126 can change the display attribute based on the change of the target parameter when being written to realize different display effects, and can recover the display attribute of the medium layer 126 when not being written to realize repeated writing, thereby realizing the effects of saving resources and facilitating writing.

Specifically, the medium layer 126 may be sprayed on the writing area 12 through a spraying process, and when the control device 21 controls the target parameter of the medium layer 126 to be changed through the pen tip 23, the display property of the medium layer 126 may be changed, for example, the color of the position of the written medium layer 126 may be changed.

Control device 21 may be disposed within an inner housing of writing control pen 20, and a user may operate writing control pen 20 to cause control device 21 to control a target parameter of medium layer 126 via nib 23, where medium layer 126 exhibits different display attributes at different target parameters.

In some embodiments, any parameter value of the target parameter of the media layer 126 corresponds to a unique display attribute. This allows the dielectric layer 126 to accurately display the corresponding display attribute.

Referring to fig. 2, in some embodiments, writing area 12 further includes a base color layer 122 below medium layer 126, and the color of base color layer 122 remains unchanged. Thus, the base color layer 122 can be exposed when the target parameters of the dielectric layer 126 are changed to make the dielectric layer 126 transparent.

Specifically, base color layer 122 may be a non-color changeable coating and dielectric layer 126 may be a color changeable coating. When the writing control pen 20 is writing in the writing area 12, the target parameter of the position of the written medium layer 126 is changed, for example, the position of the written medium layer 126 is in a transparent state, so that the color of the base color layer 122 is exposed, that is, when the user uses the writing control pen 20 to write, the written handwriting is in the color of the base color layer 122. In addition, when the writing area 12 is not operated by the writing control pen 20 for a preset time, the position of the previously written medium layer 126 is restored to the non-transparent filling color, that is, the previously written handwriting disappears. The time for the written medium layer 126 to return to the opaque fill color is determined by the characteristics of the paint.

In some embodiments, the display properties of the dielectric layer 126 are transparent when the parameter value of the target parameter is greater than or equal to the color change threshold. When the parameter value of the target parameter is less than the color change threshold, the display attribute of the dielectric layer 126 is a non-transparent filling color. Therefore, the effect of repeated writing can be achieved, and the user experience is good.

It is understood that the dielectric layer 126 corresponds to a color change threshold, and the size of the color change threshold is determined by the characteristics of the dielectric layer 126 itself. When the parameter value of the target parameter controlled by the control device 21 through the pen tip 23 is greater than or equal to the color change threshold value, that is, the parameter value of the target parameter at this time may change the display property of the medium layer 126 so that the display layer is transparent. When the parameter value of the target parameter is smaller than the color change threshold, that is, the parameter value of the target parameter may not change the display property of the dielectric layer 126, so that the dielectric layer 126 still maintains the original non-transparent filling color.

Specifically, in one embodiment, the medium layer 126 may be made of white paint, so that when the writing control pen 20 writes in the writing area 12, if the parameter value of the target parameter is greater than or equal to the color-change threshold value, the display property of the medium layer 126 is transparent to expose the color of the base color layer 122, and the positions of the other unwritten medium layers 126 are still white, so that the written handwriting is more conspicuous.

Referring to fig. 4, in some embodiments, writing area 12 includes a plurality of media layers 126. The plurality of dielectric layers 126 have different opaque fill colors and different color-change thresholds, respectively. In this manner, the control device 21 can control the parameter values of the target parameters of the plurality of medium layers 126 through the pen tip 23 to make the plurality of medium layers 126 appear as transparent or non-transparent filling colors, so that writing in a plurality of colors can be realized on the writing board 10.

Referring to fig. 5, in some embodiments, the writing control pen 20 includes a plurality of control keys 22 corresponding to the plurality of medium layers 126, and the control device 21 is configured to control parameter values of target parameters of the plurality of medium layers 126 through the pen tip 23 when one control key 22 is activated. After a control key 22 is triggered, the parameter value of the target parameter of the plurality of dielectric layers 126 is greater than or equal to the color-changing threshold value of the dielectric layer 126 corresponding to the control key 22, so that all the dielectric layers 126 with the color-changing threshold value less than or equal to the parameter value are displayed as transparent, and the uppermost dielectric layer 126 with the non-transparent filling color or the above-mentioned base color layer 122 is displayed.

In this manner, the control device 21 is used to control the parameter values of the target parameters of the plurality of medium layers 126 through the pen tip 23 when a control key 22 is activated so that the plurality of medium layers 126 appear transparent, so that the medium layer 126 appearing as a non-transparent filling color or the base color layer 122 is exposed, thereby enabling writing in multiple colors on the tablet 10.

Specifically, the plurality of control keys 22 may be pressing type control keys 22, touch type control keys 22, and the like.

It is to be understood that one control 22 corresponds to a respective one of the dielectric layers 126. When a control key 22 is triggered and writing is performed, the parameter values of the target parameters of all the medium layers 126 are correspondingly changed, so that one or more medium layers 126 with the color change threshold lower than or equal to the parameter values are transparent, and the medium layer 126 with the non-transparent filling color as the uppermost layer or the base color layer 122 is exposed, so that writing in multiple colors can be realized on the writing board 10.

In some embodiments, multiple media layers 126 are arranged in a stacked arrangement on writing area 12 from top to bottom or from bottom to top according to the order of color change threshold magnitude. Thus, when a control key 22 is activated, the parameter value of the target parameter of the plurality of medium layers 126 is gradually increased or decreased, and the display property of each medium layer 126 is sequentially displayed along with the change of the parameter value. It should be noted that the speed of the parameter value change of the target parameter can be adjusted to make the sequential display of the display attributes of the medium layers 126 invisible or imperceptible, and to directly display the medium layer 126 of the non-transparent filling color on the uppermost layer.

Specifically, in one embodiment, a plurality of dielectric layers 126 are arranged in a stacked arrangement from top to bottom over writing area 12 according to the order of color change threshold magnitude. In another embodiment, multiple dielectric layers 126 are stacked from bottom to top in order of color change threshold size over writing area 12.

Specifically, referring to fig. 4, in another embodiment, the number of the dielectric layers 126 is 3, which are respectively a first dielectric layer 126a, a second dielectric layer 126b and a third dielectric layer 126c, and the first dielectric layer 126a, the second dielectric layer 126b, the third dielectric layer 126c and the base color layer 122 are sequentially stacked from top to bottom. The color change threshold of the first dielectric layer 126a is less than the color change threshold of the second dielectric layer 126b, and the color change threshold of the second dielectric layer 126b is less than the color change threshold of the third dielectric layer 126 c. The number of control keys 22 is also 3. When the first control 22 is activated, the first dielectric layer 126a becomes transparent to expose the opaque fill color of the second dielectric layer 126 b. When the second control 22 is activated, both the first dielectric layer 126a and the second dielectric layer 126b become transparent to expose the opaque fill color of the third dielectric layer 126 c. When the third control key 22 is activated, the first dielectric layer 126a, the second dielectric layer 126b and the third dielectric layer 126c all become transparent to expose the base color layer 122. After a period of time without being operated, all of the dielectric layers 126 may return to atmospheric environmental parameter values (e.g., room temperature, solar wavelength, etc.). In a preferred embodiment, the value of the atmospheric environment parameter is lower than the color change threshold of the first medium layer 126a, the color change threshold of the second medium layer 126b, and the color change threshold of the third medium layer 126c, so that all of the medium layers 126 are returned to the opaque fill color, and thus the only opaque fill color present on the writing board 10 is the first medium layer 126a, i.e., the unwritten "whiteboard" mode.

Therefore, the present embodiment and all the above-mentioned embodiments have the common advantage that, on the one hand, all the patterns drawn on the writing board 10 will be self-cleared in an unoperated period of time without manual intervention. The automatic clearing without human intervention provides convenience for users, all colors (or other display attributes) are the colors (or other display attributes) of the dielectric layers 126 under a specific environment, no data can be left after the dielectric layers are restored to a white board mode, and the safety is remarkably improved; on the other hand, the writing of the tablet 10 can be realized without digitalization or energy supply by using the physical characteristics that each medium layer 126 presents different display attributes (including but not limited to colors) under different environments (including but not limited to light, temperature, current, voltage, etc.), in other words, the tablet 10 itself can realize paperless display even without electricity, and can present multiple display attributes (including but not limited to colors) at the same time, and the requirement of matching multiple hardware is also saved while energy is saved.

In some embodiments, the medium layer 126 is a temperature sensitive paint layer, the target parameter is temperature, and the control device 21 is used for controlling the temperature of the pen tip 23. The control device 21 is adapted to control the temperature of the medium layer 126 via the tip 23 when the tip 23 is in contact with the writing area 12. In this way, the control device 21 can control the temperature of the medium layer 126 through the pen tip 23, so that the display property of the medium layer 126 can be changed to enable the acted part of the medium layer 126 to be in a light-transmitting state, the operation is convenient, and the materials are easy to obtain.

Referring to fig. 4, in some embodiments, the dielectric layers 126 include a first dielectric layer 126, a second dielectric layer 126b and a third dielectric layer 126c arranged in sequence from top to bottom; when the temperature of the first dielectric layer 126 is greater than or equal to the first color-changing threshold value, the first dielectric layer 126 is transparent, and when the temperature of the first dielectric layer 126 is less than the first color-changing threshold value, the first dielectric layer 126 is a first non-transparent filling color; when the temperature of the second dielectric layer 126b is greater than or equal to the second color-changing threshold value, the second dielectric layer 126b is transparent, and when the temperature of the second dielectric layer 126b is less than the second color-changing threshold value, the second dielectric layer 126b is a second non-transparent filling color; when the temperature of the third dielectric layer 126c is greater than or equal to the third color-changing threshold value, the third dielectric layer 126c is transparent, and when the temperature of the third dielectric layer 126c is less than the third color-changing threshold value, the third dielectric layer 126c is a third non-transparent filling color; wherein the first color change threshold is less than the second color change threshold, and the second color change threshold is less than the third color change threshold; the first non-transparent filling color, the second non-transparent filling color and the third non-transparent filling color are different.

Like this, the relative temperature of predetermineeing of nib 23 output of control writing control pen 20 is so that the dielectric layer 126 that corresponds among a plurality of dielectric layers 126 presents for transparent state, can expose the non-transparent filling color of corresponding dielectric layer 126 or the colour of base colour layer 122 like this to make the user can write the handwriting of different colours on writing region 12 through writing control pen 20, the colour of writing is various, writes conveniently, and user experience nature is good.

It is understood that in other embodiments, the control key 22 may include a touch sliding area, and the pen tip 23 may be controlled to output a corresponding preset temperature by sliding operation on the touch sliding area.

Specifically, in the present embodiment, a base color layer 122 is first sprayed on the writing area 12, and then medium layers 126 are sprayed on the base color layer 122 layer by layer, and the color change threshold corresponding to each medium layer 126 is different. It should be noted that, the plurality of dielectric layers 126 are stacked from top to bottom, and the color change threshold corresponding to each dielectric layer 126 is gradually increased. When the relative preset temperature output by tip 23 of writing control pen 20 exceeds the corresponding color change threshold of media layers 126 and writing control pen 20 acts on writing area 12, one or both or more of media layers 126 may become transparent to expose the non-transparent fill color of the uppermost media layer 126 or the color of base color layer 122.

Specifically, referring to fig. 4 and 5, in one embodiment, the dielectric layer 126 is thermochromic ink. The dielectric layers 126 include three dielectric layers 126, a first dielectric layer 126a, a second dielectric layer 126b, and a third dielectric layer 126 c. The color change threshold of the first dielectric layer 126a corresponding to the first dielectric layer 126a is 20 ℃, and the non-transparent filling color of the first dielectric layer 126a is white. The color change threshold of the second dielectric layer 126b corresponding to the second dielectric layer 126b is 30 ℃, and the non-transparent filling color of the second dielectric layer 126b itself is green. The color change threshold of the third dielectric layer 126c corresponding to the third dielectric layer 126c is 40 ℃, and the opaque filling color of the third dielectric layer 126c itself is red. The base color layer 122 itself is yellow in color. The control keys 22 comprise a first temperature control key 222a, a second temperature control key 222b and a third temperature control key 222c, wherein the preset temperature input by the first temperature control key 222a is 20 ℃. The preset temperature inputted by the second temperature control key 222b is 30 deg.c. The preset temperature output by the third temperature control key 222c is 40 ℃.

When the first temperature control key 222a is operated, the preset temperature output by the pen tip 23 of the writing control pen 20 is 20 ℃, and when the writing control pen 20 writes on the writing area 12, the first medium layer 126a of the medium layer 126 to be written is changed into a transparent state, and the second medium layer 126b and the third medium layer 126c maintain the non-transparent filling color of the medium layer 126 c. That is, as the first media layer 126a changes to a transparent state, the opaque fill color of the second media layer 126b is exposed, and green writing is visible.

When the second temperature control key 222b is operated, the preset temperature output by the pen tip 23 of the writing control pen 20 is 30 ℃, and when the writing control pen 20 writes on the writing area 12, the first medium layer 126a and the second medium layer 126b in the written medium layer 126 become transparent, and the third medium layer 126c maintains the non-transparent filling color of the third medium layer 126 c. That is, since the first medium layer 126a and the second medium layer 126b become transparent, the opaque filling color of the third medium layer 126c is exposed, and at this time, red writing is seen.

When the third temperature control key 222c is operated, the preset temperature output by the pen tip 23 of the writing control pen 20 is 40 ℃, and when the writing control pen 20 writes on the writing area 12, the first medium layer 126a, the second medium layer 126b and the third medium layer 126c of the written medium layers 126 become transparent. That is, since the first medium layer 126a, the second medium layer 126b and the third medium layer 126c become transparent, the color of the base color layer 122 is exposed, and at this time, yellow handwriting is seen.

In some embodiments, the medium layer 126 is a photosensitive coating layer, the target parameter is one of light wavelength, light frequency and light intensity, and the control device 21 is used for controlling the light emitted from the pen tip 23. Control device 21 is configured to control the wavelength, frequency or intensity of light received by medium layer 126 through tip 23 when tip 23 is in optical contact with writing area 12. Therefore, the operation is convenient, and the materials are easy to obtain.

Specifically, the photosensitive coating layer can be photochromic ink. The photochromic ink is an ink that changes color by means of a substance, for example, an ultraviolet photochromic ink, an ultraviolet fluorescent photochromic ink, an infrared excited photochromic ink, and the like. When the writing control pen 20 outputs the corresponding light source 224, the corresponding medium layer 126 becomes transparent.

In one embodiment, referring to fig. 2 and 6, the dielectric layer 126 is a uv sensitive color-changing ink, and the dielectric layer 126 is purple. The base color layer 122 is green. The writing control pen 20 outputs ultraviolet light. When the writing control pen 20 writes in the writing area 12, the written medium layer 126 is partially changed to a transparent state, so that the color of the base color layer 122 is exposed, that is, the written handwriting is green.

In another embodiment, the dielectric layer 126 is an infrared photochromic ink, and the dielectric layer 126 itself is red. The base color layer 122 is green. The writing control pen 20 outputs infrared light. When the writing control pen 20 writes in the writing area 12, the portion of the medium layer 126 to be written becomes transparent, which exposes the color of the base color layer 122, i.e., the writing is red.

Referring to fig. 7, in some embodiments, the dielectric layers 126 include a first dielectric layer 126, a second dielectric layer 126b and a third dielectric layer 126c arranged in sequence from top to bottom; when the target parameter received by the first medium layer 126 is greater than or equal to the first discoloring threshold, the first medium layer 126 is transparent, and when the target parameter received by the first medium layer 126 is less than the first discoloring threshold, the first medium layer 126 is a first non-transparent filling color; when the target parameter received by the second medium layer 126b is greater than or equal to the second discoloring threshold, the second medium layer 126b is transparent, and when the target parameter received by the second medium layer 126b is less than the second discoloring threshold, the second medium layer 126b is a second non-transparent filling color; when the target parameter received by the third dielectric layer 126c is greater than or equal to the third color-changing threshold value, the third dielectric layer 126c is transparent, and when the target parameter received by the third dielectric layer 126c is less than the third color-changing threshold value, the third dielectric layer 126c is a third non-transparent filling color; wherein the first color change threshold is less than the second color change threshold, and the second color change threshold is less than the third color change threshold; the first non-transparent filling color, the second non-transparent filling color and the third non-transparent filling color are different.

So, the nib 23 of control writing control pen 20 outputs corresponding light wavelength, light frequency or light intensity so that corresponding dielectric layer 126 appears for transparent in a plurality of dielectric layers 126, can expose the non-transparent filling color of corresponding dielectric layer 126 or the colour of base colour layer 122 like this to make the user can write the handwriting of different colours on writing region 12 through writing control pen 20, the colour of writing is various, it is convenient to write, user experience nature is good.

Specifically, in the present embodiment, a base color layer 122 is first sprayed on the writing area 12, and then dielectric layers 126 are sprayed on the base color layer 122 layer by layer, and the activation wavelengths corresponding to the dielectric layers 126 are different.

Specifically, referring to fig. 7 and 8, in one embodiment, the color of the base color layer 122 is green. The dielectric layer 126 is a photochromic ink. The dielectric layers 126 include a first dielectric layer 126a and a second dielectric layer 126 b. The first medium layer 126a is sprayed with ultraviolet photochromic ink, the activation wavelength of the first medium layer 126a is ultraviolet light output by the writing control pen 20, and the non-transparent filling color of the first medium layer 126a is purple. The second medium layer 126b is coated with infrared optically variable ink, the activation wavelength of the second medium layer 126b is infrared light output by the writing control pen 20, and the non-transparent filling color of the second medium layer 126b itself is red. The control keys 22 include a first light source control key 226a and a second light source control key 226b, wherein the light output by the first light source control key 226a is ultraviolet light. The light output from the second light source control key 226b is infrared light.

When the first light source control key 226a is operated, the light output from the pen tip 23 of the writing control pen 20 is ultraviolet light, and when the writing control pen 20 writes on the writing region 12 and the light output from the pen tip 23 of the writing control pen 20 reaches the position of the medium layer 126, the first medium layer 126a is in a transparent state, and the second medium layer 126b maintains its opaque filling color. That is, as the first media layer 126a changes to a transparent state, the opaque fill color of the second media layer 126b is exposed, and a red script is seen. On this basis, when the second light source control key 226b is operated again, the light outputted from the pen tip 23 of the writing control pen 20 is an infrared light, and when the user writes again at a position where a red writing is displayed, the second medium layer 126b becomes a transparent state, thus exposing the color of the base color layer 122, that is, the red writing becomes a green writing.

Specifically, the light source 224 of the present embodiment may be an LED light source, an IGB light source, or the like, and the type of the light source 224 is not limited herein and may be set according to actual requirements.

In some embodiments, referring to fig. 1, tablet 10 includes a memory 14 and a processor 16, where processor 16 is configured to process writing of writing control pen 20 in writing area 12 and store the writing of writing control pen 20 in memory 14. Therefore, the effect of saving the handwriting is achieved, and the user can check the handwriting conveniently.

In some embodiments, referring to fig. 1, the tablet 10 includes a transmission module 18, and the transmission module 18 is used for transmitting the handwriting stored in the memory 14 to the terminal 200. Therefore, the user can conveniently review the content of the handwriting.

Specifically, the transmission module 18 may be a bluetooth module, a WiFi module, etc., and is not limited herein. The cloud 200 may be a mobile phone terminal, a tablet computer, and the like, and is not limited herein.
