Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a display screen with defogging function. Background Technology

[0002] A display screen is a device used to display information such as images, text, and video. It is commonly found in various electronic devices, such as televisions, computers, smartphones, tablets, and monitors. It is a display tool that displays certain electronic documents onto a screen through a specific transmission device. It can be divided into cathode ray tube displays (CRT), plasma displays (PDP), and liquid crystal displays (LCD). Chinese utility model patent CN221592386U discloses a display screen, including: a mounting bracket with symmetrically symmetrically arranged mounting holes; a fixing strip fixedly installed on the side wall of the mounting bracket; a first sliding groove on the side wall of the fixing strip; and a second sliding groove symmetrically arranged in the inner wall of the first sliding groove; a display mechanism including a fixed base fixedly connected to an inner rod; symmetrically arranged vertical strips on the side wall of the fixed base; a display screen body positioned above the fixed base; symmetrically fixedly installed vertical blocks at the lower end of the display screen body; screws rotatably installed inside the two vertical blocks; threaded rings threaded at both ends of the screws; the two threaded rings respectively engaging with the two vertical blocks; and a fixing ring fixedly installed at the lower end of the display screen body, with a traction rope installed inside the fixing ring. This existing technology, through the design of the display body, vertical blocks, screws, and threaded rings, causes the two vertical blocks to rotate on the screw when the display body is flipped. When the display body is adjusted to a suitable angle, the two threaded rings can be tightened at both ends of the screw to limit the position of the two vertical blocks. This makes it easier to adjust the installation position and angle during use, making the device more convenient to use.

[0003] The aforementioned prior art has the following shortcomings in actual operation: In actual use, during winter or humid weather, the product's inner surface will fog up due to temperature differences. The fog will only slowly dissipate after the equipment has been turned on for a period of time. Since the product surface is not equipped with a heating mechanism, the fog cannot be eliminated quickly, thus affecting the normal transmission of the content displayed on the screen. Utility Model Content

[0004] The purpose of this invention is to provide a display screen with a defogging function to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A display screen with defogging function includes a fixing plate, a mounting mechanism, and a defogging mechanism, wherein the defogging mechanism includes:

[0007] A connecting plate is disposed on the front side of the mounting mechanism.

[0008] The display screen body is connected to the front side of the connecting plate;

[0009] An adhesive layer is connected to the front side of the display screen body;

[0010] A heating film is connected to the front side of the adhesive layer, and its two end electrodes are connected to the motherboard of the peripheral product.

[0011] The frame is attached to the front side of the heating film. More specifically, the frame is an OCA optical adhesive or a double-sided adhesive frame.

[0012] Optionally, the defogging mechanism further includes a support frame and a rotating pipe, the rear side of the support frame being connected to the front side of the mounting mechanism, the rotating pipe being rotatably connected to the front side of the support frame, and the rear side of the connecting plate being connected to the front side of the rotating pipe.

[0015] Optionally, the mounting mechanism further includes a telescopic groove and a spring. The telescopic groove is formed on the right rear side of the mounting block. A telescopic tube is connected to the inner wall of the telescopic groove. One end of the telescopic tube is connected to a control plate. The spring is connected to the left rear side of the control plate. The spring is located on the outside of the telescopic tube. The left side of the spring is connected to the left side of the inner wall of the telescopic groove.

A screw is connected to the rear side of the upper rotating frame, and a threaded tube is threaded onto the surface of the screw. One end of the threaded tube is rotatably connected to a lower rotating frame. A lower hinge frame is hinged to the rear side of the lower rotating frame, and the bottom of the lower hinge frame is connected to the top of the T-shaped block.

[0018] Optionally, the adjustment mechanism further includes a control ring connected to the surface of the threaded tube.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) By attaching the adhesive layer to the surface of the liquid crystal screen on the front side of the display body of the connecting plate, and connecting the electrodes at both ends of the heating film connected to the frame layer to the main board of the product, the heating purpose is achieved by applying voltage and current through software control. In this utility model, the installation and replacement of the defogging component is more convenient. The start-up time is controlled by software, and the heating is turned on in advance before the display body is used normally to quickly remove fog, ensuring that the content displayed on the display is transmitted normally from the time of power-on, improving the speed of fog removal when the display body is used, ensuring that the display content is clearly visible, and solving the problems in the prior art.

[0029] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0030] like Figures 1-6 As shown in the figure, this utility model embodiment provides a display screen with defogging function, including a fixing plate 1, a mounting mechanism 2, a defogging mechanism 3, and other parts.

[0031] The connecting plate 303 is located on the front side of the mounting mechanism 2. The display screen body 304 is connected to the front side of the connecting plate 303. The adhesive layer 305 is connected to the front side of the display screen body 304. The heating film 306 is connected to the front side of the adhesive layer 305. The electrodes at both ends of the heating film 306 are connected to the motherboard of the peripheral product. The heating film 306 achieves the purpose of heating by applying voltage, current and running time through software control. Specifically, the electrodes of the heating film 306 are led to the interface of the display screen through a flexible circuit board (FPC) or wires and connected to a specific power interface on the device motherboard. The pre-set control program on the motherboard can output a rated DC power of 5V / 1A to the interface when the device is started, with a duration of 3 minutes, in order to achieve the purpose of rapid defogging.

[0032] Specifically, the defogging mechanism 3 also includes a support frame 301 and a rotating pipe 302.

[0033] The rear side of the support frame 301 is connected to the front side of the mounting mechanism 2, the rotating pipe 302 is rotatably connected to the front side of the support frame 301, and the rear side of the connecting plate 303 is connected to the front side of the rotating pipe 302.

[0034] In use, the rotatable connection between the rotating tube 302 and the support frame 301 provides room for adjusting the tilt angle of the display body 304. The adhesive layer 305 is attached to the liquid crystal screen surface of the display body 304 on the front side of the connecting plate 303. The heating film 306 connected to the rear side of the frame layer 307 generates heat under the control of the peripheral software to perform defogging.

[0035] Furthermore, to facilitate the installation and removal of the display screen, the display screen with defogging function also includes a mounting mechanism 2.

[0036] Specifically, such as Figures 1-6 As shown, the mounting mechanism 2 includes a mounting hole 201 and a mounting block 202.

[0037] Among them, the mounting hole 201 is opened on the front side of the fixing plate 1, and the rear side of the mounting block 202 is connected to the front side of the fixing plate 1.

[0038] Specifically, the mounting mechanism 2 also includes a T-slot 203 and a T-block 204.

[0039] The T-shaped groove 203 is formed on the top of the mounting block 202, and the T-shaped block 204 is slidably connected to the inner wall of the T-shaped groove 203.

[0040] Specifically, the mounting mechanism 2 also includes a telescopic groove 205 and a spring 208.

[0041] The telescopic groove 205 is located on the right rear side of the mounting block 202. The inner wall of the telescopic groove 205 is connected to the telescopic tube 206. One end of the telescopic tube 206 is connected to the control plate 207. The spring 208 is connected to the left rear side of the control plate 207. The spring 208 is located on the outside of the telescopic tube 206. The left side of the spring 208 is connected to the left side of the inner wall of the telescopic groove 205.

[0042] Specifically, the installation mechanism 2 also includes a baffle 209 and a retaining groove 210.

[0043] Among them, the baffle 209 is connected to the left front side of the control plate 207, the bottom of the baffle 209 is attached to the upper surface of the T-shaped block 204, the groove 210 is opened on the right front side of the mounting block 202, and the inner wall of the groove 210 is slidably connected to the side of the baffle 209.

[0044] In use, after fixing the fixing plate 1 by passing the bolt through the mounting hole 201, place the T-shaped block 204 in the T-shaped groove 203, release the control of the control plate 207, and under the control of the elastic force of the spring 208 in the telescopic groove 205, the telescopic tube 206 shortens. The shortening of the telescopic tube 206 drives the baffle 209 to be inserted into the baffle groove 210 until the bottom of the baffle 209 is attached to the upper surface of the T-shaped block 204 and fixes it.

[0045] Furthermore, in order to adjust the tilt angle of the display screen, the display screen with defogging function also includes an adjustment mechanism 4.

[0046] Specifically, such as Figure 2-6 As shown, an adjustment mechanism 4 for adjusting the tilt angle is connected to the upper rear side of the display body 304.

[0047] The adjustment mechanism 4 includes an upper hinge frame 401 and an upper rotating frame 402. The upper hinge frame 401 is connected to the upper rear side of the display screen body 304. The upper rotating frame 402 is hinged to the rear side of the upper hinge frame 401. A screw 403 is connected to the rear side of the upper rotating frame 402. A threaded tube 404 is threadedly connected to the surface of the screw 403. A lower rotating frame 406 is rotatably connected to one end of the threaded tube 404. A lower hinge frame 407 is hinged to the rear side of the lower rotating frame 406. The bottom of the lower hinge frame 407 is connected to the top of the T-shaped block 204.

[0048] Specifically, the regulating mechanism 4 also includes a control ring 405.

[0049] Among them, the control ring 405 is connected to the surface of the threaded tube 404.

[0050] In use, rotating the control ring 405 causes the threaded tube 404 on one side of the lower rotating frame 406, which is rotatably connected to the lower hinge frame 407, to rotate, adjusting the distance between the screw 403 and the threaded tube 404 connected to the upper rotating frame 402 to a suitable length, and at the same time causing the display screen body 304 connected to the upper hinge frame 401 to rotate, adjusting the tilt angle of the display screen body 304 to the target value.

[0051] The heating film 306, which is stacked in layers, can directly and evenly heat the display screen body 304 after being powered on, thus achieving a fast and efficient defogging function.

[0052] By connecting the electrode leads to the peripheral motherboard, the heating timing and duration can be intelligently controlled by the software program (such as preheating before power-on, and heating triggered by the humidity sensor), resulting in a high degree of automation and a good user experience.

[0053] The sliding engagement between the T-block 204 and the T-slot 203, along with the locking structure of the baffle 209 driven by the spring 208, enables quick assembly and disassembly of the display screen, facilitating maintenance.

[0054] The electrode leads of the heating film 306 are connected to an external interface (such as a board-to-board connector or pads) via a flexible printed circuit board (FPC) or insulated wires (not shown in the figure). This external interface is electrically connected to the power control circuitry pre-installed on the main control circuit board (i.e., the 'peripheral product motherboard') inside the device.

[0055] The main control circuit board integrates a control unit (such as an MCU) and a drive circuit (such as a MOSFET switch). The control unit has a pre-stored control program that can be configured to issue commands to the drive circuit under at least one of the following conditions, causing the drive circuit to conduct and provide the heating film 306 with its rated operating voltage (e.g., 5V or 12V DC):

[0056] (1) When the device receives the power-on signal, it first starts the heating film 306 to work for a period of time (e.g., 30 seconds), and then turns on the display screen backlight;

[0057] (2) When the built-in humidity sensor of the device detects that the ambient humidity is higher than a preset threshold (such as 85%RH);

[0058] (3) Users can trigger the defogging function by manually pressing a button or by pressing a software button on the touch screen.

[0059] The heating film 306 generates heat after being powered on. The heat is conducted through the adhesive layer 305 to the glass substrate of the display body 304, raising the surface temperature of the screen above the dew point temperature, thereby eliminating fog and preventing the formation of new condensation.

[0060] The frame adhesive layer 307 is a transparent optical adhesive layer, which can ensure good optical transmittance and transfer the heat generated by the heating film 306 to the outermost layer of the screen more evenly.

[0061] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
