2 Message from President
Thank you for your understanding and support for JOLED’s management philosophy, research and development activities and business promotion.
JOLED was founded in 2015 with the goal of accelerating mass production development and commercialization of OLED displays. In 2017, we commercialized printed OLED for the first time in the world. Then, we expanded production as well as our customer network, while continuing to develop further advanced technologies. In 2019, we started operation of our mass-production line. From there, we will bring our medium-sized high- resolution printed OLED to the market, targeting for high-end monitors, Our mission at JOLED is to realize a world filled with excitement and medical monitors, signage and automotive displays. emotion through our cutting-edge devices. With products that people
Display panels have become an integral part of modern life. Displays are always want to carry, experience, wear, and more, we offer new now too familiar in everyday life and people may spend a long time without experiences that strike a chord. By achieving this, we could perhaps being aware of it. Because of it, we hope to embody and provide the values enrich people’s spirits, provide convenience, and even improve that displays of this era should have, such as eye-friendly, stress-free lifestyles. And perhaps can we even make a small contribution to usability, and exceptional visual expressions. enriching people’s lives. We will continue taking on new challenges to achieve this innovation. In the technology licensing business, which is our core business along with the product business, we concluded capital and business alliance with TCL I would like to ask for your kind and continuous support.
CSOT last year and started joint development of large-sized printed OLED. We aim to further develop printed OLED technology as a pioneer and to take Tadashi Ishibashi it from a technology trend to the de facto standard in the industry. Representative Director and President, JOLED Inc.

11 What is OLED ?
How does OLED emit light? Electron transport layer Organic Light Emitting Diode (OLED) is a kind of light- Host material emitting diode (LED) that uses organic compound to emit
Guest material light. In OLED, the emissive electroluminescent (EL) layer Emitting layer is formed by a film of organic compound that emits light in response to the current flow.
Exciton generation →Excitation energy conversion OLED device is composed of two electrodes and several Hole transport layer →Light emission from guest functional layers: electron transport layer (ETL), emitting material layer (EML), and hole transport layer (HTL), etc. When a
bias is applied between anode and cathode electrodes, electron and hole recombine in the EML and emit light in response to the current flow.
12 What is OLED ?
Structure of OLED display
OLED has a simple structure in which an organic EL layer sandwiched between electrodes is again sandwiched between a front glass substrate and a TFT formed rear glass substrate.

Proprietary TRIPRINTTM Technology
The proprietary TRIPRINTTM technology, which forms RGB subpixels by printing, enables to produce superior performance displays in efficient production process.
Performance Advantages
Features of JOLED display are: “RGB Printed EL Layer” to realize great light efficiency, “Microcavity Structure” to realize high color purity by sharpening RGB lights, and “Top Emission” to realize high light utilization.

Proprietary TRIPRINTTM Technology
The proprietary TRIPRINTTM technology, which forms RGB subpixels by printing, enables to produce superior performance displays in efficient production process.
Process Advantages
With JOLED’s proprietary TRIPRINTTM technology, RGB sub pixels are formed at once by printing. It is processed under atmospheric pressure without vacuum chamber nor metal mask. There is no material waste because it puts necessary quantity of materials onto target points by printing. The technology has also scalability merit because panels in variety of sizes can be manufactured with the same print head.
15 Difference of OLED Manufacturing Methods
There are two types of method to manufacture OLED display; “Evaporation White Vapor RGB Vapor RGB Printing Deposition Method Deposition Method Method method” and “Printing method”. There are also two types of EL layer; “White OLED” in which three layers are deposited in laminated structure to emit white
color (White Vapor Deposition OLED), and “RGB OLED” in which three different light emitting layers are deposited side-by-side (RGB Vapor Deposition OLED
and RGB Printed OLED).
Evaporation method, currently used by major companies, forms EL layers by
evaporating EL materials in vacuum chambers. It requires large vacuum chambers to accommodate panel and vapor deposition source, and metal masks to form Vacuum process Vacuum process Atmospheric pressure process the EL layer on only target points. Area mask Fine metal mask No mask
Especially in RGB Vapor Deposition Method, it deposits each RGB layer
individually and requires three times of fine mask than White Vapor Deposition Method. When the screen size becomes bigger or number of pixels rises, it
becomes more difficult to align the mask onto target points. In addition,
extremely low efficiency in material utilization and the difficulty in depositing uniform thin films are the issues for this technology. 4 pixels 3 pixels 3 pixels
Bottom emission Top emission Top emission In the case of White Vapor Deposition Method, although the difficulty of aligning
12 layers 12 processes 4 layers 12 processes 3 layers 3 processes the mask is alleviated, colors are produced by color filter and it causes loss of 3/4 of lights, and color purity contradicts light utilization efficiency.
JOLED manufactures OLED displays by using the highly productive RGB printing Large OLED for TV Small and medium OLED Medium OLED for monitor for smartphone and and signage method, which overturns the issues of the vapor deposition method. We also aim laptop Large OLED for TV to share this manufacturing technology with our partners and establish it as an
industry standard technology.

Flexible Display
Flexible display is a display that can be rolled, folded, or bended like a paper or cloth. With its ultra-thin and light profile, it can realize displays more freely designed or easy to store.
JOLED is researching and developing various flexible displays. A super light in weight, flexible and high performance display can be realized by replacing the conventional glass substrate to the plastic substrate, and using the oxide TFT. We are aiming at developing flexible OLED for practical use in near future.

TAOS TFT Technology
To realize excellent performance of OLED, it is required high current flow to run for the thin film transistor (TFT).
Actually JOLED display uses low temperature poly-silicon (LTPS) TFT. LTPS TFT has good performance to run the high current flow but has same tasks such as non-uniform TFT performance due to the crystallization process and high manufacturing cost.
JOLED is now focusing on developing TAOS TFT (Transparent Amorphous Oxide Semiconductor) which has high electron mobility for high current flow and is uniformly formed on the large substrate.
We have developed a novel self-aligned top-gate TFT and realized superior reliability, by using a technology to passivate TFT electrode by metallic reaction. Also putting our unique correction circuit technology, we will realize high quality but reasonable OLED displays using our TAOS TFT.
