Description

Technical Field

[0001] This utility model belongs to the field of resistive touch screen technology, and in particular relates to a resistive touch screen that prevents light leakage. Background Technology

[0002] A resistive touchscreen consists of a lower conductive ITO layer (glass or thin film material) and an upper conductive ITO layer (thin film material), separated by tiny insulating dots. When there is no pressure on the touchscreen surface, the upper and lower circuits are open. Once pressure is applied to the touchscreen, the upper and lower circuits become conductive. The controller applies a driving voltage in the X-coordinate direction through the lower conductive ITO layer and detects the voltage in the X-coordinate direction through probes on the upper conductive ITO layer. From this, the X-coordinate of the touch point is calculated. By changing the direction of the applied voltage, the Y-coordinate of the touch point can be measured, thus determining the position of the touch point.

[0003] However, when existing resistive touchscreens are subjected to external impacts in actual use, due to the lack of an effective protective structure, the glass base or plastic layer of the touchscreen is prone to cracking or scratching. This not only affects the display effect of the screen, but may also cause the touch function to malfunction. Moreover, when water splashes on the screen, the water may seep into the interior through the gaps in the screen, causing corrosion to the internal conductive layer and electronic components, and shortening the lifespan of the touchscreen.

[0004] To address this issue, we provide a resistive touchscreen that prevents light leakage. Utility Model Content

[0005] The purpose of this invention is to provide a resistive touchscreen that prevents light leakage. By combining an optical film, an optical adhesive layer, a black adhesive layer, and protective components, it solves the problem that existing resistive touchscreens lack an effective protective structure and are easily damaged when subjected to external forces and water stains.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a light-leakage-proof resistive touchscreen, comprising an outer frame, a touchscreen body disposed within the inner cavity of the outer frame, a protective component disposed on the front of the outer frame, an optical film disposed on the surface of the touchscreen body, an optical adhesive layer disposed on one side of the optical film, and a black adhesive layer disposed on the other side of the optical adhesive layer, the protective component comprising a rotating shaft, one end of the rotating shaft being movably connected to one side of the outer frame, and a protective cover being fixedly connected to the other end of the rotating shaft, grooves being formed on both sides of the inner cavity of the outer frame, a fixed shaft being fixedly connected to the top and bottom of the inner cavity of the grooves, a movable plate being movably connected to the surface of the fixed shaft, a spring being sleeved on the surface of the fixed shaft, a connecting strip being fixedly connected to one side of the movable plate, and a protective film being fixedly connected to one side of the connecting strip, positioning grooves being formed at the top and bottom of the inner cavity of the outer frame, and a drainage groove being formed on one side of the inner cavity of the positioning groove.

[0008] The present invention is further configured such that a sealing block is provided in the inner cavity of the drainage channel, and a pressing strip is fixedly connected to one side of the sealing block. Moving the pressing strip causes the sealing block on one side to be inserted into the inner cavity of the drainage channel, thereby sealing the inner cavity of the drainage channel and preventing a large amount of external dust from entering the inner cavity of the outer frame from the drainage channel.

[0009] The present invention is further configured such that a limiting strip is fixedly connected to one side of the front of the outer frame, and one side of the limiting strip is in contact with the surface of the protective cover. When the protective cover is rotated to completely cover the front of the outer frame, one side of the protective cover is in contact with the surface of the limiting strip, and the magnetic side of the limiting strip attracts the protective cover, preventing the protective cover from rotating easily.

[0010] The present invention is further provided that a pressure point pad is fixedly connected to one side of the front of the protective cover, and the surface of the pressure point pad is provided with anti-slip particles, making it more convenient to press the pressure point pad with your fingers and rotate the protective cover through the pressure point pad.

[0011] The present invention is further configured such that a positioning piece is provided in the inner cavity of the positioning groove, and a sealing strip is fixedly connected to one side of the positioning piece by adhesive. One side of the sealing strip is fixedly connected to the surface of the protective film. The top and bottom of the protective film are fixed to the inner cavity of the positioning groove by the sealing strip, which can prevent water stains from seeping in from the gap between the top and bottom of the protective film and the inner cavity of the outer frame.

[0012] The present invention is further configured such that a sealing line is fixedly connected to the side of the protective cover facing the outer frame, and one side of the sealing line is in contact with the surface of the outer frame. When the protective cover is rotated to cover the outer frame, the sealing line on one side of the cover is in tight contact with the surface of the outer frame. The sealing line can improve the sealing between the protective cover and the outer frame and prevent water stains from seeping in.

[0013] The present invention is further configured such that a connecting wire is provided at the bottom of the outer frame, and a protective sleeve is fixedly connected to the bottom of the outer frame and outside the connecting wire. The connecting wire is connected to an external device, so that the touch screen can be installed on the designated device.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model has good protective performance and can effectively prevent external forces from scratching the touch screen body. During operation, when the finger presses the protective film, the protective film drives the movable plate to move, so that the operation is smooth. When the pressure is released, the protective film quickly detaches from the surface of the touch screen body under the action of the spring, which does not affect the normal use of the touch screen body and can effectively protect it.

[0016] 2. The light leakage prevention optical film of this utility model is composed of an optical film, an optical adhesive layer, and a black adhesive layer. It can prevent backlight leakage and improve the quality of display effect. At the same time, the design of the drainage channel allows water stains flowing onto the surface of the protective film to flow smoothly along the surface of the protective film to the drainage channel and flow out quickly, thus avoiding water stains from corroding the touch screen body in all aspects.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-6 This utility model relates to a light-leakage-proof resistive touchscreen, comprising an outer frame 1, a touchscreen body 2 disposed within the inner cavity of the outer frame 1, a protective component 3 disposed on the front of the outer frame 1, an optical film 4 disposed on the surface of the touchscreen body 2, an optical adhesive layer 5 disposed on one side of the optical film 4, and a black adhesive layer 6 disposed on the other side of the optical adhesive layer 5. The protective component 3 includes a rotating shaft 301, one end of which is movably connected to one side of the outer frame 1, and the other end of which is fixedly connected to a protective cover 302. Grooves 303 are provided on both sides of the inner cavity of frame 1. Fixed shafts 304 are fixedly connected to the top and bottom of the inner cavity of grooves 303. Movable plates 305 are movably connected to the surface of fixed shafts 304. Springs 306 are sleeved on the surface of fixed shafts 304. Connecting strips 307 are fixedly connected to one side of movable plates 305. Protective films 308 are fixedly connected to one side of connecting strips 307. Positioning grooves 309 are provided on the top and bottom of the inner cavity of outer frame 1. Drainage grooves 310 are provided on one side of the inner cavity of positioning grooves 309.

[0028] Specifically: Rotate the protective cover 302 until it is completely offset from the front of the outer frame 1. Use your finger to operate and press on the surface of the touch screen body 2. When your finger touches the touch screen body 2, it will press the protective film 308. The protective film 308 is pressed, which drives the movable plate 305 to move on the surface of the fixed shaft 304. After the finger pressure on the surface of the protective film 308 is removed, the protective film 308 is detached from the surface of the touch screen body 2 under the action of the spring 306. The protective film 308 does not affect the normal operation of the touch screen body 2 and prevents external force from scratching the touch screen body 2. When external water stains flow onto the surface of the touch screen body 2, they will flow along the surface of the touch screen body 2 to the drainage groove 310 and flow out through the drainage groove 310 without corroding the touch screen body 2.

[0029] Example 2

[0030] Please see Figure 1-6Based on Embodiment 1, the inner cavity of the drainage groove 310 is provided with a sealing block, a pressing strip is fixedly connected to one side of the sealing block, a limiting strip is fixedly connected to one side of the front of the outer frame 1, one side of the limiting strip is in contact with the surface of the protective cover 302, a finger pressure pad is fixedly connected to one side of the front of the protective cover 302, the surface of the finger pressure pad is provided with anti-slip particles, the inner cavity of the positioning groove 309 is provided with a positioning piece, a sealing strip is fixedly connected to one side of the positioning piece by glue, one side of the sealing strip is fixedly connected to the surface of the protective film 308, a sealing line is fixedly connected to the side of the protective cover 302 facing the outer frame 1, one side of the sealing line is in contact with the surface of the outer frame 1, a connecting wire 7 is provided at the bottom of the outer frame 1, and a protective sleeve is fixedly connected to the bottom of the outer frame 1 and outside the connecting wire 7.

[0031] Specifically: Move the pressing strip so that the sealing block on one side is inserted into the inner cavity of the drainage groove 310 to seal the inner cavity of the drainage groove 310, preventing external dust from entering the inner cavity of the outer frame 1 in large quantities from the drainage groove 310. When the protective cover 302 is rotated until it completely covers the front of the outer frame 1, one side of the protective cover 302 contacts the surface of the limiting strip. The magnetic side of the limiting strip holds the protective cover 302 in place, preventing the protective cover 302 from rotating easily. Pressing the pressure pad with your finger makes it easier to rotate the protective cover 302. The top and bottom of the protective film 308 are fixed to the inner cavity of the positioning groove 309 by the sealing strip, which can prevent water stains from seeping into the gap between the top and bottom of the protective film 308 and the inner cavity of the outer frame 1. When the protective cover 302 is rotated until it covers the outer frame 1, the sealing line on one side of it is in close contact with the surface of the outer frame 1. The sealing line can improve the sealing between the protective cover 302 and the outer frame 1, preventing water stains from seeping in. Connect the connecting wire 7 to the external device, and the touch screen can be installed on the designated device.

[0032] The working principle of this utility model is as follows: The resistive touch screen is connected to the designated device through the connecting wire 7. The protective cover 302 is rotated until it is completely offset from the front of the outer frame 1. The finger is used to operate and press on the surface of the touch screen body 2. When the finger touches the touch screen body 2, it will press the protective film 308. The protective film 308 is pressed and drives the movable plate 305 to move on the surface of the fixed shaft 304. After the finger pressure on the surface of the protective film 308 is removed, the protective film 308 is detached from the surface of the touch screen body 2 under the action of the spring 306. The protective film 308 does not affect the normal operation of the touch screen body 2 and prevents external force from scratching the touch screen body 2. When external water stains flow to the surface of the touch screen body 2, they will flow along the surface of the touch screen body 2 to the drainage groove 310 and flow out through the drainage groove 310 without corroding the touch screen body 2. The optical film 4, the optical adhesive layer 5, and the black adhesive layer 6 are used to form the anti-light leakage optical film 4. The setting of the anti-light leakage optical film 4 can prevent backlight leakage.
