Huawei Mate 20 Pro uses a new Flexible OLED DDIC and Touch Controller by Synaptics

The Huawei Mate 20 Pro was announced earlier today, and it will undoubtedly be one of Huawei’s most popular devices for the next year. As usual, it packs in a ton of awesome and bleeding-edge features: an in-display fingerprint scanner, triple cameras on the back, a beefy battery, and even reverse wireless charging. One of the stars of the show is its beautiful 6.39-inch OLED display, which uses new technology from Synaptics.

Synaptics announced today that the Huawei Mate 20 Pro is the first to use their new complete display system solution, which includes Synaptics’ flexible chip-on-film (COF) ClearView display driver and their ClearPad touch controllers. Their new flexible COF packaging is capable of folding the necessary display drivers underneath the front display panel, obscured from view, to minimize the bottom bezel of the Huawei Mate 20 Pro, and to provide as much visible screen real estate as possible on the front of the device.

While Samsung’s mobile DDIs on their COF have been capable of folding for a while now, the process significantly raises the price of assembly for the entire device, which OEMs receive even higher margins for. With Synaptics now boasting competition by providing the same state-of-the-art folding capability, there is less reliance on Samsung to provide the steep demands for flexible display solutions, which could make it more feasible for OEMs to implement a gorgeous bezel-less construction on their next phones.
