Since its birth, touch screen technology has continued to develop and innovate, and touch screen types have emerged to adapt to different industries and different needs. Currently, they have been widely used in mobile phones, tablet computers, financial industry, retail industry, industrial control and monitor, entertainment and catering, public information inquiry and education systems, and other fields, bringing great convenience to people’s lives.The Global Touch Screen Display Market scale was valued at USD 65.60 Billion in 2021 and $66.91 billion in 2022. The global market for touch screen display is expected to reach USD 163,10 billion by 2029, growing from USD 66,91 billion in 2022 to USD 166,12 billion by 2029 at a compound annual growth rate of 13.9%.The touch screen display industry chain can be divided into three sections: the upstream, the midstream and the downstream. The upstream of the touch screen industry chain is manufacturers of raw materials, touch sensors and electronic components. The main raw materials include glass substrates, ITO conductive glass, polarizers, color filters, etc.; The midstream is touch screen manufacturers, which use various upstream materials to manufacture touch screens; The downstream are manufacturers of various types of touch terminal equipment, using midstream touch screens to integrate various complete products.In the touch display industry chain, touch screens are in the middle reaches of the industry and play an important role in the development of the entire touch display industry. Sorted by the size of the terminal product’s panel, touch screens can be divided into small-size panels (1 to 3 inches), medium-size touch screens (3 to 10.4 inches), and large-size touch screens (10.4 inches or larger). Small and medium-sized touch screens generally refer to touch screens smaller than 10.4 inches. Small and medium-sized touch screens are mainly used in products such as mobile phones, PDAs, digital cameras (DC), digital camcorders (DV), vehicle displays (such as GPS, vehicle DVD, etc.); large-sized touch screens (larger than 10.4 inches) are mainly used in notebook computers, LCD products such as monitors and LCD TVs.Due to the huge scale of investment in large-size touch screen production lines and the large size of the glass substrates used, in order to reduce packaging and transportation risks and costs and better control product production costs, the large-size touch screen industry generally requires upstream, mid-stream and downstream manufacturers to be as close as possible; if the local supply chain is not complete and sound, it will directly lead to high production costs.In the touch screen industry chain, the core competitiveness of enterprises lies in whether they master innovative touch screen technology independently. Touch screen manufacturers and companies with independent R&D capabilities and having their own intellectual property rights will have strong competitive advantages. In the assembly and debugging stages, companies with strong manufacturing, assembly and testing capabilities also have certain competitive advantages.Key players of touch display industry are Displax, Samsung, AD metro, Atmel Corporation, Microsoft Corporation, Fujitsu Ltd., 3M, Elo, BOE Technology, Sharp, NEC Corporation, Qisda Corp., AU Optronics, Panasonic, LG Electronics, etc. Most of companies in touch display industry mainly focus on the small-size capacitive screen manufacturing and supplying. In recent years, many companies have vigorously launched consumer capacitive screen projects, which has further intensified competition in the small-size touch screen industry such as mobile phones. With the development of the medium and large size touch screen market, companies that specialize in medium and large size touch screens will have greater opportunities. At present, in the medium and large size touch screen market, leading companies include ELO, TouchSystems, 3M, etc. ELO and 3M specialize in surface acoustic wave screens and infrared screens respectively.The market for touch screen displays is divided into Asia Pacific, North America, Latin America, Europe and Middle East & Africa in terms of region.

Capacitive touch screen is a kind of display utilizing the electrical properties of the human body as an input way. When a finger or input device like a stylus comes in contact with the display it detects when and where on the display the touches are. Capacitive screens are mainly divided into two types: surface capacitive screens and projected capacitive screens, and projected capacitive screen technology is divided into self-capacitance and interactive capacitance. 1. Surface Capacitive ScreensSurface capacitive touch screens sense touch behaviour on the screen surface through electric field induction. Its panel is evenly coated with an ITO layer. Each of the four corners of the panel has an outlet wire connected to the controller. During operation, a uniform electric field is generated on the surface of the touch screen. When a grounded object touches the screen surface, the electrodes can sense the change in charge on the screen surface and identify the coordinates of the touch point.Surface capacitive touch screens have long service life and high light transmittance, but have low resolution and do not support multi-touch. They are currently mainly used in large-size outdoor touch screens, such as public information platforms (POI), public service (sales) platforms (POS), etc.2. Projected Capacitive ScreenProjected capacitive touch screens utilize electrostatic field lines emitted by touch screen electrodes for sensing. Projected capacitive sensing technology can be divided into two types: self-capacitance and interactive capacitance.Self-capacitance is also called absolute capacitance. It uses the sensed object as the other plate of the capacitance. The object induces charge between the sensing electrode and the sensed electrode, and the touch position is identified by detecting changes in the coupling capacitance. But if it is a single touch, through capacitance changes, there is only one set of coordinates identified in the X-axis and Y-axis directions, and the combined coordinates are also unique. If there are two points touched on the touch screen and the two points are not in the same X direction or the same Y direction, and there are two coordinate projections in the X and Y directions respectively, four coordinates will be combined. Obviously, only two coordinates are real, and the other two are commonly known as "ghost points". Therefore, self-capacitive screens cannot achieve real multi-touch.Interactive capacitance is also called crossing capacitance. It is the capacitance generated by the coupling of adjacent electrodes. When the sensed object is close to the electric field line from one electrode to another electrode, the change in interactive capacitance will be sensed. When the horizontal electrodes send out stimulation signals in sequence, all the vertical electrodes receive the signals at the same time. In this way, the capacitance value of the intersection of all horizontal and vertical electrodes can be obtained, that is the capacitance of the entire two-dimensional plane of the touch screen. When human fingers approach, the local capacitance will decrease. Based on the two-dimensional capacitance data change of the touch screen, the coordinates of each touch point can be calculated. Therefore, even if there are multiple touch points on the screen, each touch point’s real coordinates can be calculated.In both types of projected capacitive sensors, the sensing capacitance can be designed in a given way that the touch of a finger is detected at any given time. The touch is not limited to one finger, but can also be multiple fingers. Since 2007, with the great success of Apple's iPhone and iPad series products, projected capacitive screens have begun to develop rapidly, quickly replacing resistive touch screens and becoming the mainstream touch technology in the market. Advantages of Projected Capacitive ScreensThe advantages of projected capacitive screens are as follows:1. High definition: Projected capacitive screens have high-resolution and high-density pixels, enabling clearer and more detailed images and text.2. Multi-touch: The projected capacitive screen supports multi-touch, allowing multiple people to operate at the same time, improving the user's interactive experience.3. Fast response speed: The projected capacitive screen has a very fast response speed and can achieve real-time response, improving the user's operating efficiency.4. Space efficiency: Projected capacitive screens can be directly projected on a flat surface or wall, without the need for additional displays.5. Good display effect: The projected capacitive screen has a very good display effect, with bright colours, high brightness and strong contrast, which can present more realistic and vivid images and videos.6. Easy to maintain: Projected capacitive screens have no mechanical parts, and are not easily damaged, enabling low maintenance costs and long service life.Projected capacitive screens have the characteristics of high sensitivity, high precision, fast response, and support multi-touch. They are widely used in electronic products such as smartphones, tablets, TVs, and car navigation systems.About Top One TechFounded in 2010, Top One Tech has been a global leader in touch technology and a world-leading supplier of touch technology, products and industry solutions since then.

The outdoor application scenarios of the display cover billboards, outdoor vending machines, outdoor smart lockers, outdoor Kiosks, etc. Touch display products used in outdoor environments need to be equipped with some special performances to resist changing outdoor environments and ensure a longer life cycle and stable work. When choosing a touch display, attention should be paid to the appropriate screen type, waterproof and dustproof capabilities, durability, brightness, contrast, etc. Screen type: Glossy screens may have better color rendering, but are prone to reflections and are not applicable to direct sunlight environments while matte screens have poorer color rendering, but better anti-glare effects and are applicable to outdoor use. Waterproof and dustproof: Rainwater, dust and other pollutants may be encountered in the outdoor environment, so touch display products should have certain waterproof and dustproof capabilities, we generally suggest a protection level of IP65 or above.Feasible in the sun: Touch displays working in an outdoor environment will definitely be exposed to the sun, so you should choose a touch monitor with high brightness and anti-glare performance. We generally suggest using 1000-2500nits brightness.Durability: Outdoor applications will face harsh environments, so durability is very important. In addition to being waterproof and dustproof, a touch screen should be anti-breakage, anti-vibration, and anti-scratch. It is necessary to make sure the touch screen can work properly in a high-temperature, low-temperature or high-humidity environment as well as in an environment where frequent shaking happens.Safety: Outdoor applications are often subject to damage by vandalism or accidental damage. It may cause the glass surface of the display to break. Keeping in mind public safety and economic loss, it is important to use touch screens that don’t shatter into small shards when hit.Reliability and stability: In an industrial outdoor environment, the touch screen needs to have good anti-interference performance and be able to work reliably and stably. It is suggested that you should study and test the quality of the touch display, the reputation of the supplier and after-sales service.Visibility: Not limited to high brightness, high contrast, and anti-glare, a wide viewing angle ensures better visibility in all environmental conditions.Top One Tech can provide you with high-quality touch screens, touch monitors, and touch computers with high brightness, high contrast, wide viewing angle, NEMA3 frame sealing standard, IP65 Waterproof and dustproof grade, wear-resistant and scratch-resistant surfaces.
