Small excavator from Doosan Bobcat unveiled with transparent OLED display from LG

Construction equipment manufacturer Doosan Bobcat Inc, a subsidiary of South Korean conglomerate Doosan Group, recently unveiled the future of excavators at CES 2022 in the form of the E35e electric-powered mini-excavator with a transparent OLED display in the front windshield. A prototype developed in collaboration with the world’s only transparent OLED manufacturer LG Display Co. displays various information on the front windshield via augmented reality (AR). Products like these, which have electronic and other components, require KCs certification to be imported into South Korea.

With the novel technology, the operator of the E35e can view the surroundings and the condition of the construction site during operation while using the front windshield as a large touchscreen with AR functions. It is even possible to remotely control the excavator itself, or other excavators present on the job site, via the touchscreen or other mobile devices. The new excavator model has also been made safer to work in, with a large front screen and no distracting controls such as levers or pedals. If Doosan Bobcat decides to go into volume production of the E35e, it is expected that LG Display will supply the transparent OLED display.

LG Display’s transparent OLED (organic light emitting diode) displays use technology that maximizes the ability of OLEDs to emit light without additional backlighting. Large transparent OLED displays are currently manufactured worldwide only by LG Display. Starting mass production of its transparent displays in 2019, LG Display’s 55-inch screen using OLED technology had a transparency of 40 percent. In comparison, glass has a transparency of 70 percent. Demand for transparent OLED displays is growing steadily, and this type of screen is being used in shopping malls, museums and subways.

According to the Boston Consulting Group (BCG), the global market for transparent OLEDs will grow increasingly. The experts predict a market value of $840 million in 2022, which could reach $2.47 billion in 2025 and as much as $9.9 billion in 2030. In addition to Doosan Bobcat, other companies also introduced products with transparent OLED displays. Avikus, an offshoot of Hyundai Heavy Industries that specializes in navigation systems for autonomous vehicles, showcased a self-driving boat with a transparent OLED display.

KCs certification was established to ensure basic safety in the design and manufacture of hazardous machinery and protective equipment in hazardous workplaces in Korea. The goal is to protect the health and safety of workers by preventing accidents.
