Custom Glass Touch Screen
Custom Glass Touch Screen is a touchscreen display with a built-in digitizer layer that converts physical interactions into digital signals. The touchscreen is a great option for businesses looking to add or replace their existing kiosks and equipment.
Resistive touchscreens use a protective cover over a transparent electrode film that contains conductive layers. When a finger comes in contact with the screen, it interrupts the current and the controller registers the touch event.
LUMINEQ provides transparent touch foil that can be embedded in any glass Custom Glass Touch Screen surface, turning it into an interactive touch screen. The screen can be used to display dynamic media content and rear projected images and video. It also functions as a digital keypad for vehicle, office room or home security systems. It can even be used to control the lighting in a building. Transparent touch screens provide endless possibilities for designers and engineers looking to break traditional design boundaries and wow customers.
The most popular type of touch screen is a resistive touch screen. These screens consist of two layers of glass and a conductive film sandwiched between them. The conductive film is coated with an ITO layer and is usually black or gray. The glass substrate is made from tempered, clear or anti-glare glass. This touch screen offers high durability and is suitable for use in harsh environments. It can be actuated by a bare finger, gloved hand or soft-tip stylus.
Another type of touch screen is a projected capacitive (P-Cap) screen. P-Cap touch screens consist of a glass substrate with embedded transparent electrode films and an IC chip. When a finger touches the screen, the ratios of the electrical currents change, which can be detected by the IC chip. These screens are more durable than resistive touch screens and can be used with a variety of materials, including surgical gloves and cotton gloves. They are also available in a variety of colors and can be customized according to customer drawings or specifications.
Touchscreens are built to withstand the wear and tear of daily use. They must be able to withstand frequent contact from fingers and other objects, as well as being exposed to high temperatures and humidity. They must also pass strict impact resistance tests, such as UL60950 ball-drop and IK06 impacts.
The most robust touchscreens are constructed using chemically hardened glass. This is produced by immersing the cut glass panels in a bath of molten salt for several hours. This process changes the surface of the glass by replacing smaller potassium ions on the surface with larger sodium ions from the salt bath.
Another way to improve the durability of resistive touch screens is by incorporating polarizer films into the sensor construction. These reduce incident light reflections from ambient lighting, enhancing display image contrast and readability. Privacy films are also available, which limit the viewable area of the screen to only those directly in front of it.
Elo’s new state-of-the-art manufacturing facility is able to customize each glass sensor and assembly, reducing production time and lowering costs for customers. This includes etching and grinding the surface of the glass to customise its appearance and functionality, as well as adding holes and slots for peripheral devices such as credit card readers or NFC detectors. Custom Glass Touch Screen Finished touch sensors can then be bonded to LCD modules with VHB perimeter bond or full optical (OLP) and OCA bonding methods.
Touchscreens can be aesthetically pleasing, blending with any design while still providing the functionality the user expects. The key to this is the use of projected capacitive technology, which uses clear conductive grids that connect through glass to system electronics, rather than using a traditional wired construction. This means that the electrodes are not visible to the end user, and surface wear like cracks or scratches are less likely to cause functional damage.
The conductive patterns can be incorporated in a variety of ways, including index-matched ITO and optically clear adhesives to reduce light transmission loss. Anti-reflective coatings can be applied to the glass, and a slightly matt surface can be used to enhance the way fingers glide over the screen. This is often referred to as ‘anti-stiction’, and it can enhance the user experience on applications that require lots of dynamic drawing or gesturing.
Zytronic can produce a virtually unlimited range of different shapes, sizes and finishes for touchscreens incorporating this technology. This flexibility is possible thanks to the company’s unique manufacturing process. The company is able to create full sheets of the required glass, and then cut it to a precise size with 3- and 5-axis CNC equipment. It can also bend and shape the glass to create curved touchscreens, and thermally temper it to meet strict safety standards.
Before capacitive touchscreens were available, resistive touchscreens were the only option for allowing users to interact with their devices. Resistive touch panels rely on pressure to activate the display. They can be actuated by bare fingers, gloves and passive stylus, but they are more susceptible to dents and scratches than other touchscreen technologies. They also have poor visibility in direct sunlight, making them less suitable for outdoor use.
In contrast, capacitive touchscreens have a glass top layer that is more durable. They can also be actuated by bare fingers, thick gloves and active stylus, but they don’t suffer from the same issues as resistive touchscreens. In addition, a crack in the screen does not interfere with the device’s functionality because the sensor measures variations in capacitance to determine where a finger has touched the screen.
The durability of a touchscreen is important for long-term use, especially in public facing environments like ATMs and gas pump displays. These screens are often exposed to high-pressure, moisture and corrosive salt spray. The use of a rugged glass top layer and chemical strengthening improves impact resistance.
