Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of touch screens, and more specifically, to a light-touch RTP structure. Background Art
[0002] With the rapid advancement of touch technology, capacitive touch screens have rapidly taken over the market with their high sensitivity, multi-touch capabilities, and excellent durability. This technology detects touch locations by sensing the body's electrical current, enabling precise operation without the need for physical pressure, bringing unprecedented user convenience. However, resistive touch screens, another important branch of touch technology, while still offering unique advantages in certain areas such as handwriting input and signature recognition, are facing significant competition from capacitive touch screens in terms of market share. Resistive touch screens rely on physical contact between two conductive layers (usually ITO, or indium tin oxide). When pressure is applied by an external object (such as a finger or stylus), the upper conductive layer deforms and contacts the lower conductive layer, completing the circuit. The location of the touch point can be calculated by measuring the voltage change at the edge of the two conductive layers.
[0003] Traditional resistive touchscreens (such as the FG structure of RTP) typically require a high operating force (typically several Newtons) to achieve effective touch, which limits the user experience. Over extended use, high operating force can not only cause finger fatigue but also affect touch accuracy and comfort. Therefore, we have improved this by proposing a light-touch RTP structure. Utility Model Content
[0004] The technical problem to be solved by the embodiments of the present invention is that conventional resistive touch screens generally require a relatively large operating force to achieve effective touch.
[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0006] A light-touch RTP structure comprises an indium tin oxide (ITO) film and an indium tin oxide (ITO) glass. An ITO protrusion is provided on a side of the ITO film close to the ITO glass.
[0007] As an improvement of the present invention, the ITO protrusion is used to reduce the contact gap between the ITO film and the ITO glass.
[0008] As an improvement of the present invention, a side of the ITO glass close to the ITO film is silk-screened with a plurality of insulating layer DOT dots.
[0009] As an improvement of the present invention, the diameter of the DOT points of the insulating layer is .mm and the spacing is .mm.
[0010] As an improvement of the present invention, the DOT dots of the insulating layer are used to support and insulate the ITO film, thereby avoiding short circuits caused by contact with the ITO protrusions.
[0011] As an improved approach of the present invention, a double-sided adhesive is bonded between the ITO film and the ITO glass, and the double-sided adhesive is arranged in a frame shape.
[0012] As an improved method of the present invention, the double-sided adhesive is used to bond the ITO film and the ITO glass together.
[0013] As an improvement of the present invention, the ITO glass has electrodes, and the electrodes are bound with FPC cables.
[0014] As an improvement of the present invention, a reinforcement portion is provided between the ITO glass and the FPC cable.
[0015] As an improved embodiment of the present invention, the reinforcing portion is a reinforcing glue, which is provided between the ITO glass and the FPC cable.
[0016] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:
[0017] To address the problem in existing resistive touch screens that typically require a high operating force to achieve effective touch, the present invention provides an ITO protrusion on the side of the ITO film closest to the ITO glass. The ITO protrusion effectively reduces the contact gap between the ITO film and the ITO glass, thereby enabling touch without applying increased force. This design reduces the operating force and greatly reduces the pressure on the human hand during touch. This is undoubtedly a great relief for users who frequently use touch devices. Whether during long hours of work or daily entertainment, it can significantly reduce the burden on the user's hands and improve user comfort. On the other hand, the reduced operating force also makes touch operations more sensitive and precise. Since the required force is reduced, users can more easily control the strength and direction during operation, thereby improving the accuracy and response speed of touch. In addition, this design also provides a softer and more convenient operating experience. The soft touch feeling makes the user feel as if they are interacting with the device in a delicate way, without any stiff touch. The convenience is reflected in the fact that users can complete various operations more easily without having to deliberately increase the force to achieve touch. Whether it is quick clicks, slides, or fine handwriting input, it can become smoother and more natural under this design. This optimized operating experience not only improves user satisfaction with the device, but also provides more possibilities for use in various application scenarios.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this utility model belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. Reference to "embodiments" herein means that the specific features, structures or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the utility model. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0024] As described in the background technology, traditional resistive touch screens (such as RTP's FG structure) typically require a large operating force (generally several Newtons) to achieve effective touch, which to a certain extent limits further improvement in user experience. Over long-term use, the large operating force may not only cause user finger fatigue, but also affect touch accuracy and comfort.
[0025] In order to solve this technical problem, the utility model provides a light-touch RTP structure.
[0026] Specifically, please refer to Figure 1-Figure 2 , the touch RTP structure specifically includes:
[0027] The ITO film 1 and the ITO glass 5 are provided with an ITO protrusion 101 on a surface of the ITO film 1 close to the ITO glass 5 .
[0028] The light-touch RTP structure provided by the present invention provides an ITO protrusion 101 on the side of the ITO film 1 close to the ITO glass 5. The ITO protrusion 101 effectively reduces the contact gap between the ITO film 1 and the ITO glass 5, so that touch can be achieved without applying increased force. This design reduces the action force; greatly reduces the pressure when the human hand touches, and provides a softer and more convenient operating experience.
[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.
[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0032] Example 1 of the light touch RTP structure of the utility model
[0033] Please refer to Figure 1-Figure 2 The light-touch RTP structure of the present invention includes: an ITO film 1 and an ITO glass 5. An ITO protrusion 101 is provided on the side of the ITO film 1 close to the ITO glass 5. By providing the ITO protrusion 101 on the side of the ITO film 1 close to the ITO glass 5, the ITO protrusion 101 effectively reduces the contact gap between the ITO film 1 and the ITO glass 5, thereby achieving touch without applying increased force. This design reduces the operating force and greatly reduces the pressure when the human hand touches, providing a softer and more convenient operating experience.
[0034] At the same time, this design also improves the touch response speed, allowing the device to detect touch signals and respond more quickly, enhancing the user experience. In addition, since the pressing force is reduced, the wear on the device is also reduced, and the service life of the device is extended; because when the ITO protrusion 101 exists, the distance between it and the ITO glass 5 is reduced, so that the finger or stylus only needs a very small force to make the ITO protrusion 101 contact with the ITO glass 5 to form a signal, thereby achieving touch coordinate detection and positioning, which greatly reduces the pressure when the human hand touches, and provides a softer and more convenient operating experience.
[0035] During operation, the surface of the ITO film 1 is pressed by a finger or a stylus. Due to the arrangement of the ITO protrusions 101 , only a small force is required to make it contact with the ITO glass 5 to generate a signal to achieve touch coordinate detection and positioning.
[0036] Furthermore, the ITO protrusion 101 is used to reduce the contact gap between the ITO film 1 and the ITO glass 5. This setting can ensure the stable generation of the touch signal and improve the reliability of the device. The stable touch signal can ensure that the device can work normally in various environments without being interfered with by the outside world. At the same time, the reliable device performance also reduces the cost of maintenance and replacement, bringing better economic benefits to users. In addition, the stable touch signal can also improve the accuracy of the device, so that it can better meet the needs of users in situations where precise operation is required, such as drawing, design, etc.
[0037] Embodiment 2 of the light touch RTP structure of the utility model
[0038] For further information on the structure of this utility model touch RTP, please refer to Figure 1-Figure 2 , a plurality of insulating layer DOT dots 2 are silk-screened on the side of the ITO glass 5 close to the ITO film 1; the insulating layer DOT dots 2 can play a supporting and insulating role, ensuring the normal operation between the ITO film 1 and the ITO glass 5, and avoiding the occurrence of short circuit. This design improves the safety of the equipment and prevents equipment damage or safety accidents caused by short circuit. At the same time, the supporting role of the insulating layer DOT dots 2 can also make the ITO protrusions 101 more stably contact with the ITO glass 5, improve the accuracy and stability of touch, and extend the service life of the equipment.
[0039] Furthermore, the diameter of the DOT point 2 of the insulating layer is 0.03mm and the spacing is 3.5mm. The above dimensions are preferred settings, and the specific dimension settings can be adjusted according to actual conditions. The appropriate diameter and spacing can ensure the insulation and support effects while not affecting the sensitivity and accuracy of the touch; the distance enables the DOT point 2 of the insulating layer to effectively realize the insulation and support functions, and will not affect the transmission and detection of the touch signal due to the point being too large or too dense. This can ensure that the device can maintain good touch performance in various usage scenarios and provide users with a stable and accurate operating experience. At the same time, the appropriate diameter and spacing can also reduce the use of materials and reduce production costs.
[0040] Furthermore, the insulating layer DOT dots 2 are used to support and insulate the ITO film 1 to avoid short circuit with the ITO protrusions 101 .
[0041] Further, such as Figure 1-Figure 2As shown, double-sided adhesive 3 is bonded between the ITO film 1 and the ITO glass 5, and the double-sided adhesive 3 is arranged in a frame shape; the frame-shaped double-sided adhesive 3 can firmly bond the ITO film 1 and the ITO glass 5 together, thereby improving the stability of the structure. This stable structure can prevent the ITO film 1 and the ITO glass 5 from being displaced or separated during use, thereby ensuring the accuracy and reliability of the touch operation. At the same time, the frame-shaped design can also play a certain sealing role, thereby preventing impurities such as dust and water vapor from entering the interior of the device and affecting the performance and life of the device; in addition, the use of the frame-shaped double-sided adhesive 3 also makes the assembly of the device more convenient and quick, thereby improving production efficiency.
[0042] Furthermore, double-sided adhesive 3 is used to bond the ITO film 1 to the ITO glass 5. This ensures a fixed relative position between the two films, facilitating accurate touch signal generation and detection. This stable relative position reduces touch signal errors caused by positional variations, improving the device's accuracy and reliability. Furthermore, this fixed positional relationship helps maintain the device's structural integrity when subjected to external forces, reducing the likelihood of damage. Furthermore, the bonding of the double-sided adhesive 3 provides a buffering effect, reducing external impacts on the device and extending its service life. Because the ITO film 1 and ITO glass 5 are bonded together using the double-sided adhesive 3, their positional relationship is more stable and less susceptible to shifting due to external forces, ensuring accurate touch signal generation and detection.
[0043] Embodiment 3 of the light touch RTP structure of the utility model
[0044] The utility model touches RTP structure further, such as Figure 1-Figure 3 As shown, the ITO glass 5 has electrodes, and the electrodes are bound to the FPC cables 4. The binding of the FPC cables 4 makes signal transmission more stable and efficient, improving the performance of the device. Stable and efficient signal transmission can ensure that the device can operate normally in various complex environments and is not easily affected by signal interference. At the same time, the softness and bendability of the FPC cables 4 also make the design of the device more flexible and can adapt to different installation requirements.
[0045] The reason is that FPC is soft and flexible, which can better adapt to different installation environments. At the same time, its good conductive properties can ensure stable and efficient signal transmission between electrodes and other components.
[0046] Further, such as Figure 1-Figure 2As shown, a reinforcement portion is provided between the ITO glass 5 and the FPC cable 4; the reinforcement portion can enhance the connection strength between the ITO glass 5 and the FPC cable 4, thereby improving the reliability of the device. The strong connection can prevent the FPC cable 4 from separating from the ITO glass 5 during use, thereby ensuring the stability of signal transmission. At the same time, the reinforcement portion can also play a certain protective role, preventing external forces from damaging the connection parts and extending the service life of the device. In addition, the enhanced connection strength also enables the device to better maintain structural integrity when subjected to vibration or impact, thereby improving the device's anti-interference ability.
[0047] The reason is that during use, the connection between the ITO glass 5 and the FPC cable 4 is easily affected by external forces and becomes loose or damaged. Providing a reinforcement portion can effectively increase the connection strength, prevent connection problems, and improve the reliability of the equipment.
[0048] Further, such as Figure 1-Figure 2 As shown, the reinforcement portion is a reinforcing glue 6, which is arranged between the ITO glass 5 and the FPC cable 4. The reinforcing glue 6 can fill the gap in the connection part to prevent moisture and dust from entering, protecting the connection part from the influence of the external environment. The sealed connection can improve the waterproof and dustproof performance of the device and extend the service life of the device. At the same time, the adhesion of the reinforcing glue 6 can further enhance the connection strength, ensuring a stable connection between the FPC cable 4 and the ITO glass 5. In addition, the use of the reinforcing glue 6 also makes the assembly of the device simpler and more convenient, thereby improving production efficiency.
[0049] Because the reinforcing glue 6 has good sealing and adhesion properties, it can tightly connect the ITO glass 5 and the FPC cable 4 together, while filling the gap in the connection part to prevent impurities such as water vapor and dust from entering, thereby protecting the connection part from the influence of the external environment and extending the service life of the equipment.
[0050] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

Any equivalent structure made using the contents of the present invention specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of protection of the present invention patent.
