Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and more specifically, to a display device and an electronic device. Background Technology
[0002] Currently, common simple concert support signs and street shop advertising signs typically use a combination of light strips and simple glass, or flat-printed advertising roll-up banners. However, these traditional advertising formats have some shortcomings: they are often quite heavy and inconvenient to carry, especially when they need to be frequently moved around the event venue or shop area. Furthermore, some flat-printed advertising roll-up banners may be discarded after a single use due to their thin material, causing a negative impact on the environment and hindering environmental protection. Summary of the Invention
[0003] This application provides a display device and an electronic device.
[0004] The display device according to the embodiments of this application is characterized in that it includes: a main module and a canvas carrier, the main module including a positive terminal and a negative terminal, the main module being disposed at one end of the canvas carrier, the positive terminal and the negative terminal extending toward the canvas carrier, the main module further including a polar pen and a dye pen, the dye pen being used to apply luminescent dye to the canvas carrier to draw target lines, and the polar pen being used to apply conductive material to the canvas carrier to connect the positive terminal and the target lines, as well as the negative terminal and the target lines.
[0005] In the display device of this application embodiment, the display device includes: a main module and a canvas carrier. The main module includes a positive terminal and a negative terminal, and is disposed at one end of the canvas carrier. The positive and negative terminals extend towards the canvas carrier. The main module also includes a polar pen and a dye pen. The dye pen is used to apply luminescent dye to the canvas carrier to draw target lines, and the polar pen is used to apply conductive material to the canvas carrier to connect the positive terminal and the target lines, as well as the negative terminal and the target lines. Thus, text or patterns desired by the user can be drawn on the canvas carrier using the polar pen and the dye pen to achieve functions such as billboards or light signs. The structure is simple and lightweight. When not needed, the luminescent dye and conductive material can be erased and reused, which is environmentally friendly.
[0006] In some embodiments, the canvas carrier includes two opposing sides, and there are two positive terminals and two negative terminals. The two positive terminals are sandwiched between the two sides of the canvas carrier, and the two negative terminals are sandwiched between the two sides of the canvas carrier.
[0007] In this way, target lines can be drawn on both sides of the canvas carrier using the positive and negative terminals, increasing the display area of the display device. At the same time, the positive and negative terminals can clamp the canvas carrier while energized, achieving a fixed connection between the canvas carrier and the main module.
[0008] In some embodiments, the conductive material of the polar pen is made of a conductive polymer material.
[0009] Thus, conductive polymer materials can be colorless and odorless conductive materials. By drawing lines on these conductive polymer materials, a conductive circuit can be formed between the luminescent dye and the positive or negative terminals.
[0010] In some embodiments, the luminescent dye of the dye brush is made of an organic luminescent material.
[0011] In this way, the dye brush can form the desired target lines on the canvas carrier through organic light-emitting materials. These organic light-emitting materials can emit light on their own after being electrified, displaying the desired graphics or text.
[0012] In some embodiments, the main module further includes a power supply and a switch, wherein the power supply is connected to the positive terminal and the negative terminal respectively, and the switch is disposed between the power supply and the positive terminal, and / or the switch is disposed between the power supply and the negative terminal.
[0013] In this way, the power supply can provide electrical energy, and the power supply drives the target to emit light through the positive and negative terminals to display the required graphics or text.
[0014] In some embodiments, the main module further includes a brightness adjustment knob disposed between the power supply and the positive and negative terminals, the brightness adjustment knob being used to adjust the output voltage of the positive and negative terminals.
[0015] Thus, the brightness adjustment knob can adjust the output voltage to the positive and negative terminals to control the brightness of the target line drawing.
[0016] In some embodiments, the main module further includes a detection module and an alarm. The detection module is connected to the positive terminal, the negative terminal, and the alarm, respectively. The detection module is used to detect the voltage between the positive terminal and the negative terminal, and to control the alarm to sound an alarm when the detection module detects that the voltage between the positive terminal and the negative terminal exceeds a threshold.
[0017] In this way, the detection module can detect the voltage between the positive and negative terminals, and control the alarm to sound when the voltage exceeds the threshold, so as to avoid the power supply short circuit causing the whole module to overheat and be damaged.
[0018] In some embodiments, the overall module further includes a storage space for accommodating the polar brush and the dye brush.
[0019] In this way, the storage space can hold polar brushes and dye brushes, making them easy to access and preventing them from being lost.
[0020] In some embodiments, the canvas carrier is a plastic film.
[0021] In this way, target drawings can be drawn on the plastic film, resulting in a better display effect.
[0022] The electronic device according to the embodiments of this application includes the display device described in any of the above embodiments.
[0023] In the display device and electronic device of the embodiments of this application, the display device includes: a main module and a canvas carrier. The main module includes a positive terminal and a negative terminal, and is disposed at one end of the canvas carrier. The positive terminal and the negative terminal extend towards the canvas carrier. The main module also includes a polar pen and a dye pen. The dye pen is used to apply luminescent dye to the canvas carrier to draw target lines, and the polar pen is used to apply conductive material to the canvas carrier to connect the positive terminal and the target lines, as well as the negative terminal and the target lines. Thus, text or patterns desired by the user can be drawn on the canvas carrier using the polar pen and the dye pen to achieve functions such as billboards or light signs. The structure is simple and lightweight. When not needed, the luminescent dye and conductive material can be erased and reused, which is environmentally friendly.

[0035] Please see Figure 1 and Figure 2The display device 100 according to the embodiments of this application is characterized in that it includes: a main module 10 and a canvas carrier 20. The main module 10 includes a positive terminal 11 and a negative terminal 12. The main module 10 is disposed at one end of the canvas carrier 20. The positive terminal 11 and the negative terminal 12 extend toward the canvas carrier 20. The main module 10 also includes a polar brush 131 and a dye brush 132. The dye brush 132 is used to apply luminescent dye to the canvas carrier 20 to draw the target outline 21. The polar brush 131 is used to apply conductive material to the canvas carrier 20 to connect the positive terminal 11 and the target outline 21, as well as the negative terminal 12 and the target outline 21.
[0036] In the display device 100 of this application embodiment, the display device 100 includes: a main module 10 and a canvas carrier 20. The main module 10 includes a positive terminal 11 and a negative terminal 12, and is disposed at one end of the canvas carrier 20. The positive terminal 11 and the negative terminal 12 extend toward the canvas carrier 20. The main module 10 also includes a polar pen 131 and a dye pen 132. The dye pen 132 is used to apply luminescent dye to the canvas carrier 20 to draw the target outline 21, and the polar pen 131 is used to apply conductive material to the canvas carrier 20 to connect the positive terminal 11 and the target outline 21, as well as the negative terminal 12 and the target outline 21. In this way, text or patterns required by the user can be drawn on the canvas carrier 20 by the polar pen 131 and the dye pen 132 to realize the function of billboards or light signs, etc., with a simple and lightweight structure. When not needed, the luminescent dye and conductive material can be erased and reused, which is beneficial to environmental protection.
[0037] Please see Figure 2 In some embodiments, the canvas carrier 20 includes two opposite sides, and there are two positive terminals 11 and two negative terminals 12. The two positive terminals 11 are sandwiched between the two sides of the canvas carrier 20, and the two negative terminals 12 are sandwiched between the two sides of the canvas carrier 20.
[0038] Thus, target lines 21 can be drawn on both sides of the canvas carrier 20 via the positive terminal 11 and the negative terminal 12, increasing the display area of the display device 100. At the same time, the positive terminal 11 and the negative terminal 12 can clamp the canvas carrier 20 when powered on, achieving a fixed connection between the canvas carrier 20 and the main module 10.
[0039] Specifically, the main module 10 is physically and securely connected to the canvas carrier 20 via positive terminal 11 and negative terminal 12. Positive terminal 11 and negative terminal 12 act as conductive and connecting structural components. For example, during actual drawing, the user can draw a positive wire 22 from positive terminal 11 using a polarized pen 131, then draw the desired target outline 21 using a dye pen 132, and finally draw a negative wire 23 from negative terminal 12 using a polarized pen 131. The target outline 21 can be connected to both the positive wire 22 and the negative wire 23. Of course, the positive wire 22 and the negative wire 23 must be kept separate on the canvas carrier 20 to avoid short circuits. At this time, the positive wire 22 and the negative wire 23 are colorless, and the target wire is a material that emits light when energized; therefore, the shape of the target wire is the graphic or text desired by the user.
[0040] In this embodiment, the specific drawing order of the target line 21, the positive wire 22 and the negative wire 23 is not limited. It is only necessary to ensure that the target line 21 can be connected to the positive terminal 11 and the negative terminal 12 through the positive wire 22 and the negative wire 23 respectively, so as to meet different requirements.
[0041] Furthermore, please combine Figure 1 During the drawing of the positive electrode wire 22 and the negative electrode wire 23, the positive electrode wire 22 and the negative electrode wire 23 can also be drawn once along the shape of the target wire. In this way, a shape with luminescent dye sandwiched between the positive electrode wire 22 and the negative electrode wire 23 can be formed. For example, when the user needs to draw the letter "B", he can first draw a line from the negative end 12 with the polar pen 131 and draw the letter "B", and then draw the target outline 21 with the dye pen 132. At this time, the dye drawn by the dye pen 132 can just cover the letter "B" of the negative electrode wire 23 without drawing the part connecting the negative end 12. Finally, draw a line from the positive end 11 with the polar pen 131 and draw the letter "B" on the dye of the target outline 21. At this time, the letter "B" is a three-layer superimposed structure of the negative electrode wire 23, the target outline 21 and the positive electrode wire 22. The lines connecting the letter "B" to the positive and negative terminals 11 and 12 respectively are non-illuminated and therefore invisible, thus allowing the letter "B" to achieve display effects such as cheering or advertising. Figure 1 In the diagram, the positive wire 22 and the negative wire 23 connected to the target letter "E" are not shown.
[0042] Specifically, the positive terminal 11 and the negative terminal 12 can also clamp the canvas carrier 20, achieving a secure connection between the canvas carrier 20 and the main module 10. This design not only enhances the stability of the display device 100, but also effectively avoids the problem of loosening or falling off between the canvas carrier 20 and the main module 10, improving the reliability and durability of the device.
[0043] Please see Figure 1 and Figure 2 In some embodiments, the conductive material of the polar pen 131 is made of a conductive polymer material.
[0044] Thus, the conductive polymer material can be a colorless and odorless conductive material. By drawing lines on this conductive polymer material, a conductive circuit can be formed between the luminescent dye and the positive terminal 11 or the negative terminal 12.
[0045] Further, please refer to Figure 1 and Figure 2 In some embodiments, the luminescent dye of the dye pen 132 is made of organic luminescent material.
[0046] In this way, the dye brush 132 can form the desired target outline 21 on the canvas carrier 20 through the organic light-emitting material. The organic light-emitting material can emit light on its own after being energized, displaying the desired graphics or text.
[0047] Specifically, the conductive material of the polar brush 131 is made of a conductive polymer. This conductive polymer is colorless and odorless, and lines drawn with it form a conductive circuit between the luminescent dye and either the positive or negative terminal 11. Due to the properties of the conductive polymer, its application on the canvas carrier 20 is very convenient. It enables current conduction and triggers a luminescent effect without affecting the appearance or quality of the canvas carrier 20, and can be easily erased when not needed. The luminescent dye of the dye brush 132 is made of an organic luminescent material. This organic luminescent material has self-luminous properties and can form the desired target lines 21 on the canvas carrier 20. When the organic luminescent material is energized, it emits light, displaying the desired graphics or text. This design allows the dye brush 132 to not only quickly and accurately achieve the desired drawing during the drawing process, but also to directly display a luminescent effect after being energized, without the need for an additional light source. This greatly simplifies the operation steps, improves production efficiency, and allows for easy erasing when not needed.
[0048] In the embodiments of this application, the specific types of conductive polymer materials and organic light-emitting materials are not limited to meet different needs. For example, the organic light-emitting material can be an organic EL material (Organic Electro-Luminescence: OEL), which emits light through current and voltage between positive and negative poles. As another example, the conductive polymer material can be made of conductive polymers, metal nanowires, or other materials.
[0049] Please see Figure 1 and Figure 2In some embodiments, the main module 10 further includes a power supply 14 and a switch 15, wherein the power supply 14 is connected to the positive terminal 11 and the negative terminal 12 respectively, and the switch 15 is disposed between the power supply 14 and the positive terminal 11, and / or the switch 15 is disposed between the power supply 14 and the negative terminal 12.
[0050] Thus, power supply 14 can provide electrical energy, and power supply 14 drives the target outline 21 to emit light through positive terminal 11 and negative terminal 12 to display the desired graphics or text.
[0051] Specifically, the power source 14 can be a battery, and the user can control the light-emitting effect on the canvas carrier 20 by simply operating the switch 15. When the switch 15 is turned on, the power source 14 supplies power to the positive terminal 11 and the negative terminal 12, thereby activating the light-emitting effect of the light-emitting material and displaying the drawn pattern or text. When the switch 15 is turned off, the power source 14 stops supplying power, and the light-emitting effect disappears, achieving convenient and quick control and energy-saving design.
[0052] Please see Figure 1 and Figure 2 In some embodiments, the main module 10 also includes a brightness adjustment knob 16, which is disposed between the power supply 14 and the positive terminal 11 and the negative terminal 12. The brightness adjustment knob 16 is used to adjust the output voltage of the positive terminal 11 and the negative terminal 12.
[0053] Thus, the brightness adjustment knob 16 can adjust the output voltage to the positive terminal 11 and the negative terminal 12 to control the brightness of the target outline 21.
[0054] Specifically, when users need to increase or decrease the brightness of the light emission, they can simply rotate the brightness adjustment knob 16. Increasing the output voltage will increase the brightness accordingly, while decreasing the output voltage will decrease the brightness. This adjustment method is very flexible and can meet the brightness requirements of different environments and usage needs, providing a more personalized and comfortable display experience.
[0055] Please see Figure 1 and Figure 2 In some embodiments, the main module 10 further includes a detection module 17 and an alarm 18. The detection module 17 is connected to the positive terminal 11 and the negative terminal 12 and the alarm 18, respectively. The detection module 17 is used to detect the voltage between the positive terminal 11 and the negative terminal 12, and controls the alarm 18 to issue an alarm when the detection module 17 detects that the voltage between the positive terminal 11 and the negative terminal 12 exceeds a threshold.
[0056] Thus, the detection module 17 can detect the voltage between the positive terminal 11 and the negative terminal 12, and control the alarm 18 to sound an alarm when the voltage exceeds the threshold, so as to avoid the power supply 14 from short-circuiting and causing the main module 10 to overheat and be damaged.
[0057] Specifically, the detection module 17 can monitor the voltage between the positive terminal 11 and the negative terminal 12 in real time. When the voltage exceeds the set safe range, the detection module 17 will immediately issue an alarm signal to alert the user via the alarm 18. This design aims to prevent short circuits or other abnormalities in the power supply 14, which could lead to overheating and damage to the main module 10, thereby ensuring the safe and stable operation of the equipment. During the process of the user drawing the positive wire 22 and the negative wire 23 on the canvas carrier 20 using the polarity pen 131, if the positive wire 22 and the negative wire 23 are short-circuited, or if the user forgets to erase the previous wire, causing a short circuit, the alarm 18 can issue a warning to the user by emitting an alarm light or an alarm sound.
[0058] Please see Figure 1 and Figure 2 In some embodiments, the main module 10 also includes a storage space 13 for accommodating a polar brush 131 and a dye brush 132.
[0059] Thus, the storage space 13 can hold polar brushes 131 and dye brushes 132, making them easy to access and preventing them from being lost.
[0060] Specifically, by providing storage space 13 inside the main module 10, users can neatly place polar brushes 131 and dye brushes 132 together, keeping them organized. This not only makes it convenient for users to access the brushes they need at any time, but also effectively prevents the brushes from being lost or scattered, improving work efficiency and tidiness, thus avoiding their loss or messy stacking.
[0061] Furthermore, the storage space 13 can also protect the brushes from the influence of the external environment, extending their lifespan. By storing the brushes in the storage space 13, the intrusion of external dust, moisture, and other factors can be reduced, keeping the brushes clean and dry, which helps maintain their good working condition.
[0062] Please see Figure 1 and Figure 2 In some embodiments, the canvas carrier 20 is a plastic film.
[0063] In this way, target drawings can be drawn on the plastic film, resulting in a better display effect.
[0064] Specifically, plastic film is thin and transparent, effectively transmitting light so that drawn patterns or text can be clearly displayed. Compared to traditional paper or cloth, plastic film has a smoother surface, is less prone to fuzzing and wrinkling, ensuring smoother and clearer lines. Furthermore, plastic film is highly durable, resistant to moisture, deformation, or tearing, and can maintain its good condition for a long time. This makes it suitable for various environments, both indoors and outdoors, ensuring stable display of drawn content.
[0065] Furthermore, in this embodiment, the specific material of the canvas carrier 20 is not limited to meet different needs. For example, the canvas carrier 20 may be made of polycarbonate (PC) and polyethylene terephthalate (PET), or other rigid film materials.
[0066] Please see Figure 3 The electronic device 200 of this application includes the display device 100 of any of the above embodiments.
[0067] In the display device 100 and electronic device 200 of this application embodiment, the display device 100 includes a main module 10 and a canvas carrier 20. The main module 10 includes a positive terminal 11 and a negative terminal 12, and is disposed at one end of the canvas carrier 20. The positive terminal 11 and the negative terminal 12 extend toward the canvas carrier 20. The main module 10 also includes a polar pen 131 and a dye pen 132. The dye pen 132 is used to apply luminescent dye to the canvas carrier 20 to draw the target outline 21, and the polar pen 131 is used to apply conductive material to the canvas carrier 20 to connect the positive terminal 11 and the target outline 21, as well as the negative terminal 12 and the target outline 21. In this way, text or patterns required by the user can be drawn on the canvas carrier 20 by the polar pen 131 and the dye pen 132 to realize the function of billboards or light signs, etc., with a simple and lightweight structure. When not needed, the luminescent dye and conductive material can be erased and reused, which is beneficial to environmental protection.
[0068] Specifically, users can use the polar brush 131 and dye brush 132 to draw the desired text or patterns on the canvas carrier 20, thereby realizing the functions of billboards or light signs, with a simple and lightweight structure. When not in use, users can erase the luminescent dye and conductive material for reuse, which is environmentally friendly and reduces resource waste. The manufacturing and use of this display device 100 is very simple, and users do not need special skills or equipment to quickly create the patterns or text they want, greatly improving flexibility and operability.
[0069] In this application embodiment, the specific type of electronic device 200 is not limited to meet different needs. For example, electronic device 200 can be a handwritten support and advertising light sign display device 100, such as concert support and street shop advertising light signs, and can also be used as an educational experimental device for children.
