Description

Technical Field

[0001] The invention relates to the field of display heating, and in particular to a main-auxiliary integrated heating component. Background Art

[0002] The reinforced LCD display module product needs to start working at a low temperature of -45℃. However, due to the characteristics of the liquid crystal material, the LCD screen itself cannot work normally at low temperatures. Therefore, a heating component needs to be designed to heat the LCD screen so that the LCD screen can start function normally in a low temperature environment.

[0003] Due to the limitation of product appearance, the shape of the heating component can only be designed as a rectangle according to the shape of the LCD screen. However, the use of this flat heating design often results in a high temperature in the middle of the LCD screen and a low temperature around it. As a result, when the LCD screen is started at low temperature, the LCD screen has uneven display around it due to its uneven surface temperature.

[0004] Usually, additional auxiliary heaters can be used to improve the heat distribution during low-temperature heating, thereby improving the problem of uneven display of the display in a low-temperature environment. However, adding auxiliary heaters will increase the design cost and also increase the assembly complexity of the product. Summary of the invention

[0005] The purpose of the present invention is to provide a main-auxiliary integrated heating component, which divides the entire heating substrate into an auxiliary heating zone and a main heating zone. They are powered by the same power supply, which simplifies the structure of the heating component; at the same time, by adjusting the power supply of the auxiliary heating zone and the main heating zone separately, it can effectively alleviate the situation where the temperature in the middle of the display is high and the temperature around it is low after the heating component is started.

[0006] In order to achieve the above-mentioned object, the present invention provides a main-auxiliary integrated heating component, the main-auxiliary integrated heating component comprises a heating power supply and a heating substrate electrically connected to the heating power supply, a heating area and an isolation area are arranged on the heating substrate, a plurality of heating areas are arranged, two adjacent heating areas are separated by the isolation area, and the isolation area is arranged in a ring shape.

[0007] The outermost heating zone is set as an auxiliary heating zone, and a second positive electrode and a second negative electrode are set at the corners of the auxiliary heating zone, and the second positive electrode and the second negative electrode are respectively located at two ends of the same side of the auxiliary heating zone;

[0008] The heating zone located inside is set as a main heating zone, and a first positive electrode and a first negative electrode are respectively set on both sides of the main heating zone;

[0009] The first positive electrode and the second positive electrode are connected to a positive electrode of the heating power source, and the first negative electrode and the second negative electrode are connected to a negative electrode of the heating power source.

[0010] Preferably, the lengths of the first positive electrode and the first negative electrode are consistent with the length of the main heating zone where they are located.

[0011] Preferably, the width of the second positive electrode and the second negative electrode is consistent with the width of the auxiliary heating zone.

[0012] Preferably, the auxiliary heating zone is provided with an adjustment electrode, the length of the adjustment electrode is consistent with the width of the auxiliary heating zone, the adjustment electrode is arranged perpendicular to the length direction of the auxiliary heating zone, and a plurality of adjustment electrodes are arranged along the length direction of the auxiliary heating zone.

[0013] Preferably, the width of the adjustment electrode is set to 0.1-10 mm.

[0014] Preferably, the number of the adjustment electrodes located on the same side gradually decreases from the middle to both ends.

[0015] The present invention also provides a design method for the main-auxiliary integrated heating assembly, the design method comprising:

[0016] Step 1: design the number and size of the heating areas and the size of the isolation areas according to the size of the display;

[0017] Step 2: designing the number of the adjustment electrodes according to the energy demand of the auxiliary heating zone;

[0018] Step three: debug the display, and adjust the size of the isolation area and / or adjust the number and position of the adjustment electrodes according to the display status of the display.

[0019] Preferably, in step 1, one isolation zone is provided, and one isolation zone separates the heated substrate into one main heating zone and one auxiliary heating zone.

[0020] Preferably, in step three, when the auxiliary heating area shows uneven display, the number and position of the adjustment electrodes are adjusted.

[0021] According to the above technical scheme, the present invention uses laser processing, etching and other methods to divide the conductive layer on the rectangular heating substrate. The insulating area obtained by the processing is the isolation area 3. Under the action of the isolation area 3, the two adjacent heating areas are insulated, and each heating area can be individually connected to the heating power supply to realize the heating function of the display.

[0022] The isolation area 3 is set in a ring shape, so that each heating area is distributed in a U-shaped manner on the heating substrate. When the temperature of the heating area at the center position is too high, a reliable heat dissipation effect can be obtained through the isolation area 3 adjacent to it, which is helpful to solve the problem of excessively high center temperature of the display.

[0023] By adopting the U-shaped heating zone, the auxiliary heating zone can cover all sides of the display, so that the four sides of the display can be heated evenly and effectively. Preferably, in order to improve the situation where the heating energy of the electrodes arranged at the four corners of the display is insufficient, the size of the second positive electrode and the second negative electrode can be reduced as much as possible while taking into account that both adjacent auxiliary heating zones can be energized, so that a more efficient and uniform heating effect can be obtained around the display.

[0024] Preferably, the isolation area 3 should be set as little as possible to reduce the number of heating areas on the heating substrate, thereby reducing the number of wiring terminals and reducing the complexity of manufacturing the main-auxiliary integrated heating component.

[0025] After the main heating area 1 is connected to the two poles of the heating power supply through the first positive electrode 11 and the first negative electrode 12, the heating power supply can provide electrical energy to the main heating area 1. The voltage between the first positive electrode 11 and the first negative electrode 12 is the voltage of the heating power supply. The heating substrate located between the first positive electrode 11 and the first negative electrode 12 generates heat after being energized, and is used to heat the middle position of the display.

[0026] The auxiliary heating zone 2 is connected to the two poles of the heating power supply through the second positive electrode 21 and the second negative electrode 22 at the four corners. The two ends of the same side are respectively set as the second positive electrode 21 and the second negative electrode 22, that is, the voltage of the heating power supply is applied to both ends of each side of the auxiliary heating zone 2. After the auxiliary heating zone 2 is powered on, the four sides generate heat in parallel.

[0027] The main heating zone 1 and the auxiliary heating zone 2 of the main-auxiliary integrated heating component are both connected to the heating power supply, the first positive electrode 11 and the second positive electrode 21 are connected to the positive pole of the heating power supply, and the first negative electrode 12 and the second negative electrode 22 are connected to the negative pole of the heating power supply. Therefore, the main-auxiliary integrated heating component only needs to set up one heating power supply, and use one heating substrate to achieve separate heating of the main heating zone 1 and the auxiliary heating zone 2. Therefore, the structural design of the heating component of the main-auxiliary integrated heating component is also very simple, and will not increase the complexity of assembly.

[0028] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0037] In the present invention, unless otherwise stated, directional words such as "adjacent, both ends, both sides" contained in the terms merely represent the directions of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0038] See also Figure 1 A main-auxiliary integrated heating component, the main-auxiliary integrated heating component includes a heating power supply and a heating substrate electrically connected to the heating power supply, a heating area and an isolation area 3 are arranged on the heating substrate, a plurality of heating areas are arranged, two adjacent heating areas are separated by the isolation area 3, and the isolation area 3 is arranged in a ring shape,

[0039] The outermost heating zone 1 is set as an auxiliary heating zone 2, and a second positive electrode 21 and a second negative electrode 22 are set at the corners of the auxiliary heating zone 2. The second positive electrode 21 and the second negative electrode 22 are respectively located at two ends of the same side of the auxiliary heating zone 2;

[0040] The heating zone located inside is set as the main heating zone 1, and the first positive electrode 11 and the first negative electrode 12 are respectively arranged on both sides of the main heating zone 1;

[0041] The first positive electrode 11 and the second positive electrode 21 are connected to the positive electrode of the heating power source, and the first negative electrode 12 and the second negative electrode 22 are connected to the negative electrode of the heating power source.

[0042] Through the implementation of the above technical solution, the conductive layer is divided on the rectangular heating substrate by laser processing, etching, etc., and the insulating area obtained by the processing is the isolation area 3. Under the action of the isolation area 3, the two adjacent heating areas are insulated, and each heating area can be individually connected to the heating power supply to realize the heating function of the display.

[0043] The isolation area 3 is set in a ring shape, so that each heating area is distributed in a U-shaped manner on the heating substrate. When the temperature of the heating area at the center position is too high, a reliable heat dissipation effect can be obtained through the isolation area 3 adjacent to it, which is helpful to solve the problem of excessively high center temperature of the display.

[0044] By adopting the U-shaped heating zone, the auxiliary heating zone 2 can cover all sides of the display, so that the four sides of the display can be heated evenly and effectively. Preferably, in order to improve the situation where the electrodes are arranged at the four corners of the display and the heating energy at the location of the electrodes is insufficient, the sizes of the second positive electrode 21 and the second negative electrode 22 can be reduced as much as possible while taking into account that both adjacent auxiliary heating zones 2 can be powered, so that the four sides of the display can obtain a more efficient and uniform heating effect.

[0045] Preferably, the isolation area 3 should be set as little as possible to reduce the number of heating areas on the heating substrate, thereby reducing the number of wiring terminals and reducing the complexity of manufacturing the main-auxiliary integrated heating component.

[0046] After the main heating area 1 is connected to the two poles of the heating power supply through the first positive electrode 11 and the first negative electrode 12, the heating power supply can provide electrical energy to the main heating area 1. The voltage between the first positive electrode 11 and the first negative electrode 12 is the voltage of the heating power supply. The heating substrate located between the first positive electrode 11 and the first negative electrode 12 generates heat after being energized, and is used to heat the middle position of the display.

[0047] The auxiliary heating zone 2 is connected to the two poles of the heating power supply through the second positive electrode 21 and the second negative electrode 22 at the four corners. The two ends of the same side are respectively set as the second positive electrode 21 and the second negative electrode 22, that is, the voltage of the heating power supply is applied to both ends of each side of the auxiliary heating zone 2. After the auxiliary heating zone 2 is powered on, the four sides are connected in parallel and the four sides heat up at the same time.

[0048] The main heating zone 1 and the auxiliary heating zone 2 of the main-auxiliary integrated heating component are both connected to the heating power supply, the first positive electrode 11 and the second positive electrode 21 are connected to the positive pole of the heating power supply, and the first negative electrode 12 and the second negative electrode 22 are connected to the negative pole of the heating power supply. Therefore, the main-auxiliary integrated heating component only needs to set up one heating power supply, and use one heating substrate to achieve separate heating of the main heating zone 1 and the auxiliary heating zone 2. Therefore, the structural design of the heating component of the main-auxiliary integrated heating component is very simple and will not increase the complexity of assembly.

[0049] In this embodiment, preferably, the lengths of the first positive electrode 11 and the first negative electrode 12 are consistent with the length of the main heating zone 1 where they are located.

[0050] Neither the first positive electrode 11 nor the first negative electrode 12 can exceed the range of the main heating area 1 .

[0051] In this embodiment, preferably, the width of the second positive electrode 21 and the second negative electrode 22 is consistent with the width of the auxiliary heating zone 2 .

[0052] The second positive electrode 21 and the second negative electrode 22 cannot exceed the range of the auxiliary heating area 2 .

[0053] In this embodiment, preferably, the auxiliary heating zone 2 is provided with an adjustment electrode 23, the length of the adjustment electrode 23 is consistent with the width of the auxiliary heating zone 2, the adjustment electrode 23 is arranged perpendicular to the length direction of the auxiliary heating zone 2, and multiple adjustment electrodes 23 are arranged along the length direction of the auxiliary heating zone 2.

[0054] The material of the adjustment electrode 23 can be conductive metals such as gold, silver, copper and their alloy materials, which are formed on the conductive layer of the heating substrate by screen printing, evaporation coating and the like, and have strong adhesion and good conductive properties.

[0055] The adjustment electrode 23 is designed to be a rectangle, and its length is the same as the width of the auxiliary heating zone 2. By setting the adjustment electrode 23 on the auxiliary heating zone 2, it is possible to short-circuit the portion of the heating substrate covered by it, thereby reducing the resistance of the auxiliary heating zone 2 where the adjustment electrode 23 is located, increasing the current in the auxiliary heating zone 2, and thereby enabling the auxiliary heating zone 2 to generate more heat during the heating process and obtain a better heating effect.

[0056] In this embodiment, preferably, the width of the adjustment electrode 23 is set to 0.1-10 mm.

[0057] The adjustment electrode 23 can reduce the resistance value of the auxiliary heating zone 2 where it is located. However, since the resistance of the adjustment electrode 23 itself is very small, according to the energy calculation formula of electric heating: Q = I 2 Rt, it can be known that the position where the adjustment electrode 23 is located hardly generates heat. Therefore, considering the requirement for temperature consistency in various parts of the display, during actual use, the width of the adjustment electrode 23 should be set as small as possible. At the same time, in order to satisfy the resistance adjustment function of the adjustment electrode 23 on the auxiliary heating zone 2, preferably, when in use, the adjustment electrode 23 can be set to have a width as small as possible and a large number of settings, that is, the resistance adjustment function of the auxiliary heating zone 2 is satisfied by setting more adjustment electrodes 23.

[0058] In actual use, the width of the adjustment electrode 23 can be designed based on the size of the display. In order to facilitate the production of the adjustment electrode 23 during the production process, a larger display requires more heating energy, and it is easier to dissipate heat at the edge. Therefore, compared with a small display, a large display is not sensitive to heat changes. Therefore, the width of the adjustment electrode 23 can be appropriately set larger to facilitate production. On the contrary, if the size of the display is small, the width of the adjustment electrode 23 needs to be set smaller so that the heating energy at each position of the auxiliary heating zone 2 can be more accurately regulated.

[0059] In this embodiment, preferably, the number of the adjustment electrodes 23 located on the same side gradually decreases from the middle to both ends.

[0060] Due to heat dissipation, the temperature in the middle of the heating substrate in the auxiliary heating zone 2 is higher than the temperature at both ends. Therefore, more adjustment electrodes 23 can be set in the middle to reduce the heat generation in the middle and achieve the purpose of uniform temperature of the auxiliary heating zone 2.

[0061] A design method for a main-auxiliary integrated heating component, the design method comprising:

[0062] Step 1: Design the number and size of the heating zones and the size of the isolation zone 3 according to the size of the display;

[0063] Step 2: design and adjust the number of electrodes 23 according to the energy demand of the auxiliary heating zone 2;

[0064] Step 3: Debug the display, adjust the size of the isolation area 3 and / or adjust the number and position of the adjustment electrodes 23 according to the display conditions of the display.

[0065] First, design the number of heating zones and the size of each heating zone according to the size of the display. Larger displays have better heat dissipation effects. Consider setting fewer isolation zones 2 and fewer heating zones. The size of the main heating zone 1 can also be set larger, and the width of the isolation zone 3 can also be set wider. Determine the number of adjustment electrodes 23 required based on practical experience, and arrange these adjustment electrodes 23 in the auxiliary heating zone 2 in the design drawing. This completes the preliminary design of the main and auxiliary integrated heating components. The main and auxiliary integrated heating components are manufactured according to the design drawing, and the debugging work of step three is carried out.

[0066] When executing step three, the problem area on the display surface can be circled on the display, and it can be determined whether the poor display in the problem area is caused by uneven temperature on the display surface. If so, it can be determined whether the temperature at that location is too high or too low, and improvements can be made corresponding to the relevant locations of the heating substrate.

[0067] In one embodiment, if the poor display is caused by the high temperature at the center position, a heat dissipation belt can be set at the display position, and laser processing, etching, etc. can be used to divide the conductive layer of the heating substrate to form an insulating dividing line. The insulating line position is non-conductive and does not generate heat, thereby reducing the heating amount at the center position.

[0068] In one embodiment, if the poor display is caused by the high temperature at the center, an isolation area 3 can be set around the display position. The isolation area 3 is non-conductive and non-heating, and can provide heat dissipation space for the main heating area 1 in the isolation area 3, thereby reducing the temperature at the center, so that the display in the main heating area 1 can display normally. Preferably, the temperature in the main heating area 1 can be adjusted by adjusting the width of the isolation area 3. The larger the width of the isolation area 3, the more obvious the heat dissipation effect, but the temperature in the isolation area 3 also needs to be considered, so the width of the isolation area 3 cannot be too large, and is usually set to 0.01-10mm, so that the energy obtained by heat dissipation on both sides can heat the display at the isolation area 3 to a sufficiently high temperature.

[0069] In one embodiment, if the display is poor due to low temperature at the edge of the display, an adjustment electrode 23 can be added to the edge of the auxiliary heating area 2 where the display is poor, and the current of the edge is increased by adding the adjustment electrode 23, thereby increasing the overall heat generation of the edge and improving the overall temperature of the edge, thereby improving the display effect of the edge of the display. Preferably, the width of the added adjustment electrode 23 is set as narrow as possible, and the position is as close as possible to the position where the temperature of the edge is higher.

[0070] In this embodiment, preferably, in step 1, one isolation zone 3 is provided, and one isolation zone 3 separates the heated substrate into a main heating zone 1 and an auxiliary heating zone 2 .

[0071] like Figure 1 As shown, the heating substrate is divided into a main heating zone 1 and an auxiliary heating zone 2 by setting an isolation zone 3. This main-auxiliary integrated heating component has a simple structural design and is easy to manufacture.

[0072] In this embodiment, preferably, in step three, when the auxiliary heating area 2 shows uneven display, the number and position of the adjustment electrodes 23 are adjusted.

[0073] When the auxiliary heating area 2 displays unevenly, the auxiliary heating area 2 can be heated uniformly by adjusting the number and position of the adjustment electrodes 23. Specifically, the adjustment electrode 23 is set at the hotter position of the auxiliary heating area 2 to reduce the resistance of the position and increase the current of the side, so that the heat generated at the lower temperature position increases. Since the resistance of the hotter position is reduced, the voltage at the position is reduced, thereby reducing the heat generated at the position. Therefore, the purpose of heating the auxiliary heating area 2 uniformly can be achieved by setting the adjustment electrode 23.

[0074] Preferably, the width of the adjustment electrode 23 is set as narrow as possible, and reliable adjustment of the current on this side can be achieved by increasing the number of adjustment electrodes 23. The narrower adjustment electrodes 23 are evenly distributed at the locations with higher temperatures, so that the heat generated at the locations with higher temperatures can be evenly distributed, avoiding local temperature increases caused by heat accumulation, and through the positions of these narrower adjustment electrodes 23, the heat obtained by heating can be effectively dispersed, thereby better achieving the purpose of temperature uniformity.

[0075] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0076] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0077] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
