Reaching out for new applications with Yeebo’s Optical Bonding technologies
The benefits of optical bonding in noticeably enhancing readability under all shades of light, preventing fogging as well as absorbing shocks and vibrations, are well-known in rugged and outdoor human-machine interfaces.
In most cases, though, optical bonding seems to be confined to a single connection between the cover lens or touch panel and TFT. When a project requires bonding multiple TFTs within a single cover lens or just a screen in a relatively wider cover lens, the approach needs a rethink.
Through extensive know-how in optically clear adhesives and bonding processes, and worldwide market experience, Yeebo has honed its technology to cater for multi-screen optical bonding. The technology, which is scalable to cover lenses as wide as 1,000 mm, is particularly suited to shelf labelling systems and digital signage applications housing several displays, rack-mounted letterbox user interfaces in broadcast studios, and consumer & professional appliances.
In a typical configuration, customers use two or more Yeebo’s 3.9” IPS TFTs (YB-TG480128S01A-N-A0) optically bonded to a single cover lens.
Yeebo’s optical bonding technologies do not stop at flat cover lenses: they now include curved surfaces to open a new array of designs and applications. From mobile ticketing devices and access control systems to marine navigation dashboards and dynamic information displays, Yeebo’s curved lenses are set to stimulate a new wave of ergonomically sound, innovative TFT designs.

Yeebo adds visual impact with Piano Black TFT displays
Designing the user interface of today’s applications is getting more refined thanks to Yeebo’s expertise in TFT module design and market applications. With vertically integrated cover lens and touch panel manufacturing, and a highly automated TFT facility, Yeebo is the natural partner for developing display solutions that push the limits of visual interface design on aesthetic, performance and functionality.
One component attracting growing interest in recent TFT designs is the cover lens. Not only does a well-crafted cover lens protect the screen from mechanical impact and weather conditions, but it also contributes to the overall visual appeal of the final product. Choosing the best cover lens no longer stops at its basic features – material, shape and décor options. New requirements demand that the TFT visible area is purely dark when the screen is inactive, blending display and cover lens with no visual distinction.
Yeebo is at the forefront of cover lens designs with a technology developed by combining low-transflective glass and an engineered optical bonding adhesive. By controlling light transmittance within the stack, the cover lens system completely conceals the TFT when inactive, creating a distinctive Piano Black look.

UART (Universal Asynchronous Receiver-Transmitter) TFT (Thin-Film Transistor) refers to a type of display system that uses UART communication to interface with a microcontroller or other embedded systems. Let’s break down the terms:
UART (Universal Asynchronous Receiver-Transmitter):
UART is a communication protocol commonly used for serial communication between devices. It is asynchronous, meaning that data is sent without a shared clock signal between the sender and receiver.
UART communication involves two pins: TX (Transmit) and RX (Receive). Data is transmitted from the TX pin of one device and received on the RX pin of the other.
TFT (Thin-Film Transistor):
TFT refers to the thin-film transistor technology used in the construction of certain types of liquid crystal displays (LCDs). TFT displays are commonly used in devices like smartphones, computer monitors, and other electronic displays.
TFT displays provide high-quality color reproduction and are known for their fast refresh rates and better image quality compared to older LCD technologies.
Now, combining UART and TFT means that the TFT display is being controlled or communicated with using UART protocols. In practical terms, this often involves sending serial data (commands and/or data) from a microcontroller or another embedded system to the TFT display to control what is shown on the screen.
For example, a microcontroller might send commands to initialize the TFT display, set the display resolution, and then send data to display images or text. The communication is typically done using specific protocols and commands that the TFT display understands.
The advantage of using UART for TFT communication lies in its simplicity and ease of implementation. It allows for a straightforward way to control the display without the need for complex wiring or dedicated display controllers.
It’s worth noting that there are other interfaces commonly used with TFT displays, such as SPI (Serial Peripheral Interface) and I2C (Inter-Integrated Circuit). The choice of interface depends on the specific requirements of the application and the capabilities of the devices involved.

Yeebo enhances TFT displays with curved lens and coating technologies
With a record number of industries actively digitalising their infrastructures, displays are an effective interface to enrich communication with the end-user. Starting with smart wearables and up to electric cars, products using TFT displays have helped push boundaries in terms of form, fit and function.
From the days when displays used to fill a fraction of the user interface area, TFTs are now taking a significant section of the front panel surface thanks to increasing pixel resolutions and touch-sensitive cover lenses that have displaced mechanical knobs and switches. Cover lenses, bonded directly to TFT or embedded in touch systems, have played a key role in expanding designers’ creativity. However, while flat surfaces and straight angles are commonplace, new designs crave 3D curves and freeform shapes to maximise user interaction and ergonomics.
As a leading manufacturer of TFTs modules and One Glass Solutions (OGS) touch panels, Yeebo has added design and manufacturing expertise in curved cover lenses projects through collaboration with industrial designers, customers and worldwide partners. Whilst dashboards in electric cars and motorcycles have adopted curved cover lenses quite earlier, applications taking advantage of this trend have extended to personal care and medical devices, ticketing and entertainment systems, portable instrumentation and telecommunication.
Specific surface treatments of the cover lens complement every customised project, be they either an anti-reflection coating for optimum sunlight readability, an anti-smudge treatment for smooth finger operation, or an anti-microbial coating for safe touching. With in-house and outsourced capabilities Yeebo is well placed to recommend the perfect surface coatings for each target application environment.
