Description

Technical Field

[0001] This invention relates to the field of liquid crystal display technology, and in particular to an adaptive wide-temperature-range stress-compensated display module. Background Technology

[0002] In the field of modern display technology, the performance and reliability of display devices are directly affected by changes in ambient temperature. With the increasing prevalence of display devices in extreme temperature environments such as aerospace, automotive, and outdoor advertising, maintaining their display performance and structural stability over a wide temperature range has become a critical issue that urgently needs to be addressed.

[0003] Applications include automotive displays, military-grade shock-resistant systems, specialized optics, aviation instruments, and outdoor electronic equipment. These devices all require maintaining their display performance and structural stability over a wide temperature range, ensuring the display panel maintains stability, reliability, and high durability under extreme temperatures.

[0004] In existing display devices, the light source is usually mounted on the bottom side of the back panel. When the display device is working, the light source emits light and generates heat, which raises the temperature in the backlight module. The temperature on the side where the light source is installed is higher than that on the side where the light source is not installed. This will cause uneven heating of the optical film, thereby affecting the optical performance of the optical film and causing uneven brightness of the backlight in the backlight module.

[0005] In existing technology, the gas inside the airbag expands due to the temperature difference between the upper and lower parts, causing the slider and conductive plate to move and change the resistance, thereby controlling the current and ensuring heating of the upper part. However, during use, the slider is affected by gravity and the mutual resistance between the two airbags after expansion, resulting in low accuracy. At the same time, when the device is under vibration for a long time, the conductive plate will also vibrate continuously, changing the contact position with the resistor and altering the resistance, thus reducing the accuracy of temperature control. Furthermore, prolonged vibration and temperature changes can damage the device. Summary of the Invention

[0006] This application provides an adaptive wide-temperature-range stress-compensated display module, which solves the problems of existing technologies that rely on the temperature difference between the upper and lower parts of the device to cause the gas in the air bag to expand, thereby moving the slider and conductive sheet, changing the resistance, and thus controlling the current to heat the upper part. However, in use, the slider is affected by gravity and the mutual resistance between the upper and lower air bags after expansion, resulting in low accuracy. At the same time, when the device is under vibration for a long time, the conductive sheet will also vibrate continuously, and the contact position between it and the resistor will change, changing the resistance, which will reduce the accuracy of temperature control. In addition, long-term vibration and temperature change can damage the device. The present application implements a sliding component 1 and a sliding component 2 diagonally arranged on both sides of the resistor, with the extension and retraction directions of the sliding rods parallel to each other. When the temperature changes, the two sliding rods slide parallel to the ground, eliminating the interference of gravity on the displacement of the sliding rods, and the two do not collide with each other. Under vibration environment, the solidified electrorheological fluid bladder locks the position of the sliding rods, and the contact point between the conductive rod and the resistor is zero-vibration, avoiding the temperature control circuit from jumping due to vibration.

[0007] This application provides an adaptive wide-temperature-range stress-compensated display module, including a display component and a compensation component;

[0012] When the temperature changes, the airbag expands, causing the sliding rod to extend and changing the current resistance;

[0013] An electrorheological fluid bladder is fixed externally to the airbag. When the whole machine vibrates, the electrorheological fluid bladder becomes energized and hardens.

[0014] As an improvement, the compensation component is located at the center of the backplate;

[0015] The sleeve has a sliding opening on one side, and the slide rod is slidably set in the sliding opening of the sleeve;

[0016] The cross-section of the sleeve sliding opening is the same as that of the slide rod, both being rectangular.

[0017] As an improvement, a telescopic cavity is formed between the sleeve and the slide rod, the airbag is located in the telescopic cavity, and the two ends of the airbag are fixed to the end of the sleeve sliding port away from its opening and the slide rod, respectively.

[0018] As an improvement, the resistor is U-shaped, with its opening parallel to the ground in both the direction of the slide bar's extension and retraction.

[0019] The U-shaped opening of the resistor faces the slider.

[0020] As an improvement, the electrorheological fluid bladder is annular and is fitted and fixed on the outer ring of the air bladder.

[0021] In the initial state, the air bladder and electrorheological fluid bladder fill the sleeve and slide rod to form a telescopic cavity;

[0022] The electrorheological fluid bladder is filled with electrorheological fluid, and an electrode layer is provided in the inner layer of the electrorheological fluid bladder. The electrode layer is connected to the circuit and is used to generate an electric field when energized.

[0023] When the circuit is energized, an electric field is generated, causing the current to change and the liquid capsule to harden.

[0024] As an improvement, the display components also include a display screen, light strips, heating elements, air cylinder one, air cylinder two, and air supply pipe;

[0025] The back panel is located on one side of the display screen, and the light strip and heating element are fixed on the back panel;

[0026] Air cylinder one and air cylinder two are symmetrically arranged, and both air cylinder one and air cylinder two are mounted on the back plate. The compensation component is located between air cylinder one and air cylinder two.

[0027] There are two gas supply pipes, corresponding to gas cylinder one and gas cylinder two respectively;

[0028] Air cylinder one is connected to the air bladder inside sliding component one through an air supply pipe, and air cylinder two is connected to the air bladder inside sliding component two through an air supply pipe;

[0029] The light strip is located below the first air cylinder, and the heating element is located above the second air cylinder.

[0030] Gas cylinder one and gas cylinder two are filled with argon gas.

[0031] As an improvement, the conductive rod inside the first slider is connected to the power supply, and the conductive rod inside the second slider is electrically connected to the heating element.

[0036] Multiple air cylinders, number one and number two, are evenly spaced on the back plate.

[0037] As an improvement, both air cylinders are made of aluminum oxide.

[0038] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0039] Firstly, slider one and slider two are arranged diagonally on both sides of the resistor. The extension and retraction directions of the two sliders are parallel vertically. When the temperature changes, the two sliders slide parallel to the ground, eliminating the interference of gravity on the slider displacement, and the two do not collide with each other. Under vibration environment, the solidified electrorheological fluid bladder locks the slider position, and the contact point between the conductive rod and the resistor is zero-vibration, avoiding the temperature control circuit from jumping due to vibration.

[0040] Secondly, a single air cylinder one or two only reflects the average temperature at the top and bottom ends of the back plate, and the compensation for local hot spots is delayed. By adding multiple air cylinders one and two, the temperature difference of each area of ​​the back plate can be captured in real time, thereby improving the response speed of the slide bar and shortening the delay of local temperature difference compensation.

However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0051] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0053] Example 1: As Figures 1-8 As shown, this application discloses an adaptive wide-temperature-range stress-compensated display module, including a display component 100 and a compensation component 200;

[0054] The display assembly 100 includes a backplate 110, a display screen 120, a light strip 130, a heating element 140, an air pump 150, an air pump 2 160, a vibration sensor 170, an air supply pipe 180, and a controller 190.

[0055] The compensation component 200 includes a resistor 210, a first slider 220 and a second slider 230; the first slider 220 includes a sleeve 221, an air bladder 222, a slide rod 223, a conductive rod 224 and an electrorheological fluid bladder 225;

[0056] The compensation component 200 is located at the center of the backplate 110;

[0057] The back plate 110 is fixed with a sleeve 221 and a resistor 210. A slide rod 223 is provided inside the sleeve 221. One side of the sleeve 221 has a sliding opening. The slide rod 223 is slidably disposed in the sliding opening of the sleeve 221.

[0058] The cross-section of the sliding port of sleeve 221 is the same as that of slide rod 223, both being rectangular.

[0059] Specifically, the rectangular cross-section of the sleeve 221 and the sliding rod 223 ensure that the sliding rod 223 does not rotate during the sliding extension and retraction process.

[0060] The airbag 222 is fixed between the sleeve 221 and the slide rod 223;

[0061] The sleeve 221 and the slide rod 223 form a telescopic cavity, and the airbag 222 is located in the telescopic cavity. The two ends of the airbag 222 are respectively fixed to the end of the sliding port of the sleeve 221 away from its opening and to the slide rod 223.

[0062] Resistor 210 is U-shaped, and its opening is parallel to the ground in both the extension and retraction directions of slide rod 223;

[0063] The U-shaped opening of resistor 210 faces the slider 220;

[0064] The conductive rod 224 is in close contact with the resistor 210 and is fixed on the slide rod 223.

[0065] Resistor 210 is made by winding copper wire around a ceramic pillar, and the conductive rod 224 is always in contact with the copper wire when it moves.

[0066] Specifically, when the temperature changes, the airbag 222 expands, causing the sliding rod 223 to extend and changing the current resistance.

[0067] The second slider 230 has the same structure as the first slider 220, and is diagonally arranged on both sides of the resistor 210, and the extension and retraction directions of the sliders 223 inside both are parallel up and down;

[0068] Specifically, the sliding rod 223 inside the second sliding member 230 and the sliding member 220 are parallel in the vertical direction of extension and retraction, which can avoid them hitting each other when they are extended and improve the accuracy of changing the resistance.

[0069] The airbag 222 is externally fixed with an electrorheological fluid bag 225. When the whole machine vibrates, the electrorheological fluid bag 225 is energized and hardens.

[0070] The electrorheological fluid bladder 225 is annular and is fitted and fixed on the outer ring of the air bladder 222.

[0071] In the initial state, the airbag 222 and the electrorheological fluid bag 225 fill the sleeve 221 and the slide rod 223 to form a telescopic cavity;

[0072] The electrorheological fluid bladder 225 is filled with electrorheological fluid, and an electrode layer is provided inside the electrorheological fluid bladder 225. The electrode layer is connected to the circuit and is used to generate an electric field when energized.

[0073] When the circuit is energized, an electric field is generated, which causes the current-changing fluid capsule 225 to harden.

[0074] Specifically, when the device is subjected to continuous vibration, the circuit is energized, causing the electrochemical fluid bladder 225 to harden, fixing the position of the slide bar 223, and preventing resistance adjustment.

[0075] The back plate 110 is located on one side of the display screen 120, and the light strip 130 and the heating element 140 are both fixed on the back plate 110;

[0076] Air cylinder 150 and air cylinder 2160 are symmetrically arranged, and both air cylinder 150 and air cylinder 2160 are mounted on the back plate 110. The compensation component 200 is located between air cylinder 150 and air cylinder 2160.

[0077] There are two gas supply pipes 180, which correspond to gas cylinder 150 and gas cylinder 2160 respectively;

[0078] Air cylinder 150 is connected to air bag 222 inside sliding member 220 through air supply pipe 180, and air cylinder 260 is connected to air bag 222 inside sliding member 230 through air supply pipe 180.

[0079] The light strip 130 is located below the first air pump 150, and the heating element 140 is located above the second air pump 160;

[0080] Gas cylinder 150 and gas cylinder 2160 are filled with argon gas.

[0081] Specifically, when the device is turned on, the lamp strip 130 and the heating element 140 turn on together. Initially, the current in the heating element 140 is small, and the heating effect is minimal. After the lamp strip 130 has been working for a long time, causing the temperature at the bottom to be higher than the temperature at the top, the argon gas in the first gas cylinder 150 expands. The expanded gas is then transported through the gas delivery pipe 180 to the air bladder 222 in the first sliding member 220, compressing the sliding rod 223. This causes the sliding rod 223 to move the conductive rod 224 on the resistor 210, reducing the distance between the two conductive rods 224 in the first sliding member 220 and the second sliding member 230. As the resistance decreases, the current applied to the heating element 140 increases, resulting in greater heating power, and the same heating is applied to the upper part. As the temperature at the upper part increases, the air bladder 222 of the second air cylinder 160 and the second sliding element 230 expands to a greater extent, thereby applying a pushing force to the conductive rod 224 inside the second sliding element 230, increasing the distance between it and the two conductive rods 224, and decreasing the resistance. This process is repeated to adjust the temperature up and down. When the temperatures in the upper and lower regions gradually become the same, the conductive rod 224 stops moving, thus providing stable heat compensation for the optical film.

[0082] The conductive rod 224 inside the first slider 220 is connected to the power supply, and the conductive rod 224 inside the second slider 230 is electrically connected to the heating element 140.

[0083] Both the vibration sensor 170 and the controller 190 are fixed on the back plate 110. The vibration sensor 170 is used to detect the overall vibration frequency of the adaptive wide temperature range stress compensation display module, and the controller 190 is electrically connected to the vibration sensor 170.

[0084] The controller 190 is electrically connected to the circuit connected to the electrorheological fluid reservoir 225, and the controller 190 is used to control the start and stop of the circuit connected to the electrorheological fluid reservoir 225.

[0085] Specifically, when the vibration sensor 170 detects a large overall vibration of the device, the signal is transmitted to the controller 190, which energizes the circuit connected to the electrorheological fluid bladder 225, thereby hardening the electrorheological fluid bladder 225, fixing the position of the conductive rod 224, and preventing temperature adjustment to avoid uncontrollable temperature caused by repeated vibration.

[0086] The backplate 110, display screen 120, light strip 130, heating element 140, vibration sensor 170, controller 190, resistor 210, conductive rod 224 and electrorheological fluid bladder 225 are all existing technologies and will not be described in detail here.

[0087] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0088] Sliding element 1 220 and sliding element 230 are diagonally arranged on both sides of resistor 210. The extension and retraction directions of their sliding rods 223 are parallel vertically. When the temperature changes, the two sliding rods 223 slide parallel to the ground, eliminating the interference of gravity on the displacement of the sliding rods 223, and the two do not collide with each other. Under vibration environment, the solidified electrorheological fluid bladder 225 locks the position of the sliding rods 223, and the contact point between the conductive rod 224 and resistor 210 is zero-vibration, avoiding the temperature control circuit from jumping due to vibration.

[0089] Example 2: In the above embodiment, the temperature is controlled by the expansion of argon gas in cylinder 150 and cylinder 160. However, during use, the heat dissipation of different areas of the back plate 110 is different. The expansion of cylinder 150 and cylinder 160 alone only reflects the average temperature of the upper and lower areas, resulting in inaccurate movement of the conductive rod 224. Therefore, the solution of Example 1 is improved, such as... Figure 1 As shown:

[0090] Multiple air cylinders 150 and 160 are provided, and all of them are connected to the airbags 222 in the corresponding sliding member 1 220 and sliding member 230 through the air supply pipe 180;

[0091] Multiple air cylinders 150 and 160 are evenly spaced on the back plate 110.

[0092] Both the 150 and 160 air pumps are made of aluminum oxide.

[0093] Specifically, multiple air cylinders 150 and 160 are evenly spaced to accurately detect temperature changes at each location. When the temperature changes, the gas expands, thereby changing the position of the conductive rod 224, changing the magnitude of the current, and thus changing the temperature.

[0094] Air cylinder 150 and air cylinder 2160 become rigid structures, and the gas inside can only be delivered to air bag 222 after it expands, so as to prevent the expanded gas from being injected into the other air cylinders 150 and air cylinder 2160, which would cause inaccurate movement. In addition, alumina has good thermal conductivity.

[0095] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0096] A single air cylinder 150 or air cylinder 2 160 only reflects the average temperature at the upper and lower ends of the back plate 110, resulting in a lag in local hot spot compensation. By adding multiple air cylinders 150 and 2 160, the temperature differences in various areas of the back plate 110 can be captured in real time, thereby improving the response speed of the slide bar 223 and shortening the local temperature difference compensation delay.

[0097] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
