45.4: High Frequency LVDS Interface for F‐HD 120Hz LCD TV

Abstract

In FHD 120Hz TV, frame rate converting IC with the MEMC (Motion Estimation and Motion Compensation) function is applied to make the 120Hz image and 2 cables with 4 port LVDS pairs are used to transmit FHD 120Hz image data. Therefore, The cost of FHD 120Hz TV System is higher than the cost of FHD 60Hz TV System. LGD(LG‐Display) have evaluated the new FHD 120Hz LCD panel with HF (High Frequency) LVDS which is the most cost‐effective way to make FHD 120Hz TV System. This paper will review the technical aspects of FHD 120Hz LCD panel with HF LVDS and cost and propose to adapt Next Generation Interface for the new standard of FHD 120Hz LCM (LCD Module) in the Future.

“…Therefore, a more suitable, very-high-speed interface is currently under development. 10 Mini-LVDS data are transmitted from the dual TCON board through four flexible flat cables (FFC), each of which corresponds to a single quarter partitioned block. Data for the outer quarter blocks are looped through each respective inner block.…”
