Sony, which is driving the OLED TV market with LG Electronics, is exhibiting OLED TVs with new features at CES and IFA after the first display of OLED TVs.
The OLED TV displayed at Sony’s booth, which was first opened on Media Day of IFA2019, did not show a woofer. Using surface acoustic technology to produce sound from the screen, Sony showcased the CES2019’s model with four actuators on the back of the OLED panel and a woofer speaker as the rear stand. However, the woofers disappeared in IFA2019.
According to exhibition officials, the secret is that the panel is arranged with six actuators, three rows of two behind the panel, so that sound can be displayed on the screen from low to high.
