The thin and tough glass also reduces screen parallax and improves touch control accuracy for better visual quality.

Custom Touch Sensor

Touchscreen is not only a part of the display system but also the primary input device too. YI YI provides various capacitive and resistive technologies to formulate different types of touch panels as needed.

Resistive Touchscreen

A resistive touchscreen comprises two layers of conductive ITO (indium tin oxide) film and ITO glass separated by transparent dot spacers. The resistive touch panel features thin, light, and lower power consumption. Also, it is pressure sensitive to have highly accurate and quick response to any input device, including finger, glove, stylus or pen. The resistive touchscreen constructs reliable and affordable solutions for restaurants, factories and hospitals due to high resistance to dust, oil, liquids and contaminants.

Capacitive Touchscreen

A capacitive type touchscreen consists of one layer of insulation glass, coated with transparent and conductive indium tin oxide (ITO) on both surfaces. Unlike a resistive touchscreen, the capacitive touch displays rely on the electrical change caused by a light touch of a finger, capacitive stylus, or electric conductive glove.

The capacitive screens feature more sensitive and accurate touch performance as glass technology advances. The advancement also leads to sharper and brighter display performance for the capacitive screens.

Projected Capacitive Touchscreen

Projected Capacitive Touchscreens (PCT) deliver highly accurate and multi-touch functionality with a matrix of conductive wires. The PCTs are widely installed in the most demanding devices like medical machines, smartphones, and tablet computers with pinpoint accuracy in tracking the motion of a finger over the screen.

Custom Touch Controller

The touch controller is usually a micro-processor IC used to send touch signals from the touch sensor to the embedded system or computer. The IC-based controller can be set on a controller board inside the system, alternatively it can be located on a flexible printed circuit (FPC) affixed to the glass touch sensor.

Anti-interference

Electrical noise can cause system shutdowns relating to signal transmission problems for medical applications. To reinforce your operational reliability and security, YI YI provides touch controllers well integrated with noise resistance technology to protect your display panels against noise interference generated by electrical devices, peripherals, and the environment.

Glove Touch

Glove touch is a great benefit for medical and patient-care applications. YI YI provides superior high Signal and Noise Ratio (SNR) solution that detects touch signal through glove for your best convenience and operational efficiency.

EMI protection / Custom EMI Shield

Electromagnetic interference (EMI), also known as radio frequency interference (RFI), is interference from external sources. This interference occurs when devices emit signals in close proximity to operating systems. Various devices such as telephones, Bluetooth speakers, microwaves, sensors, and others can cause EMI. Regardless of the industry you operate in, ensuring a reliable, uninterrupted display is paramount.Shielding against EMI requires a combination of factors such as material impedance, conductivity, and shielding capability, and often requires a combination of specialized shielding designs and techniques to ensure that the effects of electromagnetic interference are effectively minimized or prevented.

We continue to pioneer new approaches to combat EMI. The effects of EMI include power fluctuations and surges that adversely affect medical equipment and industrial controls. As a result, EMI shielding is critical and provides several benefits, including increased system reliability, uninterrupted operation of electronic displays and seamless system functionality.Our EMI shielding can serve as a barrier to the electromagnetic interference that can cause your display to malfunction.Several strategies can be used for EMI shielding in display technology.

Metal mesh in touch panel / cover glass or lens

Metal mesh belongs to a kind of conductive material, its shape looks like a barbecue grill composed of very fine Cover glass metal wires. This technology is different from the traditional ITO conductive layer, which uses silver, copper metallic materials or silver oxides to create a conductive metal mesh pattern on a PET film.Moire patterns are interference patterns that occur when two similar but slightly offset patterns or grids overlap. These patterns can often appear as unwanted visual artifacts in various types of displays, such as LCDs, monitors, or printed materials. To minimize or eliminate unwanted moire effects, our engineer evaluated, fine-tuned, and configured the display on a case-by-case basis to optimize the display's performance to achieve better visual clarity and reduce interference for a better.

EMI Shielding – ITO Glass

ITO glass is a type of conductive ITO glass substrate with electrostatic (EMI) shielding capabilities. It is SiO2 produced by sputtering a layer of indium tin oxide (ITO), commonly Glass abbreviated as ITO, onto a base of sodium calcium or silicon boron based glass in a vacuum environment. This manufacturing structure gives the glass its EMI shielding ability while maintaining high transparency and excellent optical performance, making it a material with high quality optical properties. This makes it well suited for many display applications that require EMI shielding. In addition, the EMI shielding effectiveness can be customized as needed to meet specific application requirements.

EMI tape / Copper foil tape

Copper foil tapes, also known as EMI shielding tapes, consist of copper foil combined with an acrylic conductive adhesive and are available in various sizes. We use copper foil tape with the panel's laminated structure design to shield the electromagnetic interference generated by the LCD.

Custom Heater for Display Solution

Extreme cold temperatures can pose a challenge to liquid crystal displays (LCDs). When exposed to colder climates, the liquid inside LCD screens becomes less agile, affecting their response speed. As a result, these conditions can cause portions of the LCD screen to darken or even cause the entire screen to go black. Exposure to extremely low temperatures for an extended period of time has the potential to cause permanent damage to the screen. In order to protect displays in the toughest weather conditions, there are a variety of solutions available for applications that require the use of displays in extreme environmental conditions. Heater is one of the option.

Heater is a small piece of flexible plastic or film which is placed on or below the LCD module. It is manufactured with a layer of conductive film on different base material. Heaters use the properties of electrically conductive materials to generate heat by applying electricity to heat the LCD screen. When the LCD screen is in a low-temperature environment, this heater helps to quickly raise the temperature of the screen to ensure proper operation and display.

The heater operates intermittently, activating only when the temperature exceeds a predetermined threshold. To regulate heater activation, a sensor is required to be integrated into the customer's product to trigger the heater when the ambient temperature reaches a critical level. When triggered, the heater is energized, creating a resistive heating effect that generates heat on the surface of the heater, which is then transferred to the LCD screen, raising its temperature to improve the alignment of the liquid crystal molecules, ensuring that the LCD can display images normally at different ambient temperatures.

Custom PET heater solution

The PET heater is a PET (polyethylene terephthalate) base material which covered with a conductive layer. When energized, these conductive materials generate heat that heats the entire film, providing temperature control and uniform heating. It helps prevent problems with condensation or curing of displays that can occur at low temperatures. It is light, thin, flexible and bendable, and has good durability for drop test.

Custom ITO heater solution

The ITO heater is constructed on a conductive transparent film with a glass substrate. When energized, the ITO material is electrically conductive and generates heat to heat the entire surface, providing temperature control and uniform heating effects. This controls the temperature of the display panel and helps prevent condensation or curing of the display at low temperatures. Because ITO is a transparent material, the ITO heater is suitable for designs that require transparency.
