S8a is targeted for middle class users. It is an OLED TV with high price/ performance ratio. With the adoption of AI graphic chip, the image quality is improved a lot. The sound effect reaches A+ level because of Dolby Atmos sound system. The hidden speaker and the frames that are integrated with the backboard make S8s look simpler. Moreover, the design of all screen makes the display area account for 97.6%, which helps users watch beyond the frames for a better visual effect. We also designed luminous texture at the bottom of the screen. The texture can be customized.
