Revolutionizing display manufacturing: The impact of XTPL’s Ultra-precise Dispensing technology

The evolution of high-tech display technology

The advancement of high-tech display technology plays a pivotal role in the development of cutting-edge products. Currently, Ultra-HD (UHD) televisions featuring 4K displays are readily available in stores, while even higher-resolution 8K screens are entering the market, albeit at steep prices for the time being. The divergence in product requirements between large-screen TVs and sophisticated smartphones, alongside tablets and computer monitors, intensifies the demand for stringent manufacturing standards. The expectation for both large and small screens to deliver sharp, vibrant images necessitates the implementation of increasingly precise tolerances. This progress is made possible by the continuous evolution of inspection technologies that keep pace with the detection of microscopic imperfections in the submicron range.

Televisions, designed for viewing at approximately a 9-ft distance, employ modern 4K UHD screens with 3840 pixels across the width. The picture quality heavily relies on the perfection of each of these pixels. Conversely, most smartphones boast relatively smaller screens, with resolutions ranging from HD (1920 × 1080 pixels) to 2K (2560 × 1440 pixels). The newest generation smartphones surpass pixel densities of 500 pixels per inch (ppi). The use of OLED technology in high-end TVs and smartphones introduces challenges, particularly in achieving air-tight encapsulation to prevent contact with oxygen and moisture, posing additional inspection obstacles.

The Display Manufacturing Process & Quality Assurance

The manufacturing process begins with the production of a large master panel substrate, subject to multiple inspection stages to ensure adherence to quality specifications. After this, the master substrate is cut into smaller pieces for integration into end-product devices, with additional processing steps and inspections carried out. For OLED displays, special encapsulation steps are necessary, requiring further inspection to guarantee successful encapsulation.

OLED technology’s capabilities, while contributing to remarkable picture quality, present challenges in inspection processes. Line-scan cameras are utilized during panel manufacturing for higher throughput, while OLED inspection demands resolutions in the submicron range. Final screen tests employ area-scan cameras with high megapixels to detect imperfections in individual pixels.

Challenges in Inspection Cameras & Technological Solutions

Inspection cameras, coupled with advanced lenses, face challenges in maintaining submicron resolution over wide fields of view for large displays. The fusion of inspection optics with microscope technology addresses these challenges, enabling submicron resolution through modern line-scan sensors. Color correction in lenses is crucial to ensure accurate testing of each color in the display.

Modern high-resolution cameras allow final tests with a single camera, enhancing throughput and reducing equipment costs. Large-format lenses enable efficient testing of various screen sizes without compromising performance.

The constant pursuit of finer image quality and diverse screen sizes necessitates ongoing advancements in imaging technology for inspection. Collaboration between manufacturers and inspection technology developers facilitates the production of affordable, high-tech gadgets that meet consumer demands.

XTPL’s Ultra-precise Dispensing technology breakthrough

XTPL’s Ultra-precise Dispensing technology provides solutions for Additive Manufacturing for Flat Panel Displays. Technology provider of ultra-precise printing. Feature size reduction solutions (1-8 µm)

XTPL operates in the nanotechnology market segment. The company is developing and commercialising its globally innovative platform technology of ultra-precise printing of nanomaterials, protected by international patent applications. The XTPL method is a breakthrough. This is because of a unique combination of several features: it is an additive method, which ensures significant time and material savings and allows the advantages of print – such as scalability, cost effectiveness, simplicity and speed – to be used in the production of advanced devices thanks to unprecedented precision (structures width 1-8 micrometres) and without a need to use electric field. Due to its platform character, this solution will find application in the broadly understood printed electronics industry. At present, the company is focusing on commercialization of its technology in the flat panel display sector.

XTPL is a supplier of advanced technology of ultra-precise printing of nanomaterials. It develops and commercializes the technology dedicated to a specific application field, using one of three models:


The company develops a technological solution dedicated to a particular application field, which is licensed to a partner who on its basis builds devices that allow the technology to be implemented in a given industry; in this case, the company generates revenue from license fees based on the sale of devices in which developed technology was implemented;

Strategic partnership:

The company develops a technological solution dedicated to a particular application field and commercializes it in cooperation with a strategic partner with whom e.g. a joint venture agreement is signed; commercialization tasks are divided between the partners in accordance with their competencies and potential; in this case, the company participates in profits achieved through mutual cooperation;

Sale of a one-stop-shop solution

the company develops a technological solution dedicated to a particular application field and uses subcontractors to manufacture the solution on the basis of its own unique IP; in this model, the company is solely responsible for setting up distribution channels and for managing the sales and support processes; the comprehensive solution is sold to the end customer; the company generates revenues from the sale of printing heads and nanoinks.

The choice of the optimal business model depends on the specific application field where the company offers its solution.

At this stage, XTPL is in business talks with two groups of interested partners. The company’s direct potential clients are manufacturers of devices used for production in a particular market sector. These devices are bought and implemented on production lines at end customers – final producers of advanced electronics (e.g. displays). Both groups of entities are important for XTPL as the company needs to obtain the fullest information about the requirements that its technology must meet so it can be effectively integrated with the partners’ systems.


Repeatable and continuous silver lines with a width of 1.0 μm, length of 25 μm printed on OLED substrate.

The printed lines have a very high aspect ratio, i.e. the height-to-width ratio after the printing head has deposited a single layer of ink, i.e. after a single “pass”.

In order to obtain a similar result by competitive methods it would be necessary to deposit conductive material multiple times at the same point with multiple “passes”, thus extending the process duration.
