China Display Optoelectronics Technology (Huizhou) Co., Ltd. is a Chinese manufacturer specializing in display modules, headquartered in Huizhou, China. The company is a key operational entity related to China Display Optoelectronics Technology Holdings Limited (HKEX: 0334), which is a public company and a subsidiary of High Value Ventures Limited, itself part of the broader TCL Technology Group Corp.. As of 2024, China Display Optoelectronics Technology Holdings Limited reported revenue of RMB 4.55 billion, with approximately 4,000 employees.
The company primarily engages in the research, development, manufacturing, and sale of liquid crystal display (LCD) modules for mobile phones and tablets. Their product offerings include TFT-LCD and CTP modules, often supplied on an Original Design Manufacturer (ODM) basis, with a focus on advanced display technologies such as In-Cell, ultra-thin, ultra-narrow, full-screen, and blind hole designs. The company is also expanding into higher-margin products, including automotive display systems, and is involved in OLED and MicroLED display development through its affiliation with TCL China Star Optoelectronics Technology (CSOT).
In terms of patent litigation, China Display Optoelectronics Technology (Huizhou) Co., Ltd. maintains a defensive posture. The company has been involved in one tracked U.S. patent infringement case, appearing solely as a defendant and never as a plaintiff. This indicates that it is an operating company defending against patent assertions, rather than an entity actively asserting its own patent portfolio.
The single notable case involving the company is Bishop Display Tech LLC v. TCL Electronics Holdings Ltd. et al., filed on March 27, 2026, in the U.S. District Court for the Eastern District of Texas [cite: tracked cases]. The inclusion of "et al." suggests multiple defendants, and TCL Electronics Holdings Ltd. is a prominent related entity within the TCL ecosystem, which sources a significant portion of its TV panels from CSOT, a related display manufacturer. The Eastern District of Texas is a well-known venue for patent litigation, often favored by patent assertion entities.
