Printing OLED is an inkjet printing technology, the three primary colours of coloured light-emitting semiconductor materials as inkjet materials and ink droplets will be sprayed onto the substrate at the designated location of direct patterning, the material utilization rate of about 90%, and is not subject to the limitations of the equipment and the large size of the fine metal mask plate.

Previously, China Optical and Optoelectronic Industry Association Liquid Crystal Branch Executive Vice President and Secretary General Liang Xinqing said in an interview that TCL Huaxing has made great progress in printing display technology through strategic cooperation with JOLED in the past few years, and is fully capable of taking the lead in realizing the industrialization of printing display in China.

From the industry manufacturers and supply chain upstream and downstream news, China’s printing OLED mass production technology has basically matured. According to the relevant industry sources to confirm, at present the domestic panel enterprises have completed the 274PPI with no colour mixing, no defects in the development of printing samples, yield and other mass production has been confirmed.

At the same time, high-precision printing technology is also being developed and verified, and it is expected that the resolution of the printing technology will exceed 300PPI next year, which can correspond to small and medium-sized OLED products, and become the OLED technology that can cover full-sized products.

TCL Huaxing brought more than 20 heavyweight products to CES 2023, such as the world’s first high screen-to-body ratio ultra-slim flexible OLED medium-sized screen, 14″, 4K resolution, 120Hz refresh rate.

According to the introduction, it has a screen-to-body ratio of 96%, with 4K ultra-high definition and 120Hz refresh rate at the same time both lightweight, the whole thickness of only 0.86mm, weighing only 119g, whether for office or watching movies, can be handy.

It is reported that the TCL Huaxing booth also showcased the world’s first 65″ 8K printed OLED, which is the world’s largest size, highest resolution and refresh rate OLED products developed based on printed OLED technology so far.

The product adopts IGZO TFT backplane process, 120Hz drive system, and ultra-high precision inkjet printing technology, using 33 million ultra-high pixels to smoothly and delicately display each frame; combined with more than 99% of DCI-P3 ultra-high color gamut and millions of contrast ratio, can bring users to top visual enjoyment.

We are developing Monitor IJP technology, oxide backplane technology, and RGB IJP technology through printed OLED technology for medium to large-size products. Compared with the traditional WOLED, the printed OLED technology has more advantages in wide color gamut, low power consumption, high resolution, transparent display and flexible display.

TCL Huaxing’s printed OLED technology has now covered a number of applications such as TVs, monitors, laptops, etc., which also includes the innovative development of medium-sized panel technology, such as High PPI development / Hybrid Oxide technology, and flexible new form products.

In addition, TCL Huaxing also brought a variety of products to CES 2023, such as the world’s first 98″ 4K 240Hz 1G1D display, the world’s highest partition 49″ R800 5000+ Zones MLED display module and 34″ WQHD 165Hz R1500 OD0 Mini LED surface gaming screen, 65″ 8K wide viewing angle light field display, 7.9″ reflective LCD flat panel, and Micro Prism (MLP) technology folding screen, among many other black technology products.
