Pixelworks, Inc. (Nasdaq: PXLW), a leading provider of innovative solutions for video and display processing, and OPPO, the world’s leading smart device manufacturer and innovator, jointly announced today that OPPO’s first The foldable smartphone Find N uses Pixelworks' efficient color and brightness calibration technology, allowing users to enjoy the consistent true color and comfortable look and feel while enjoying the novel screen experience of "mobile phone to tablet".

The concept of foldable mobile phones has been proposed in the past few years, and many manufacturers have successively launched related products. For video and game enthusiasts, foldable mobile phones can not only provide a large-screen entertainment experience similar to a tablet, but are also convenient to carry, realizing the vision of combining mobile phones and tablets into one in a true sense. However, the realization of a foldable mobile phone from concept to technology is not simple. Different barriers need to be overcome, such as the balance between the folding method and the screen protector, how to deal with the crease of the screen after folding, and how the color and brightness of the folding screen are presented. Always maintain a real and comfortable look. The launch of OPPO Find N is also a response to these challenges.

The new OPPO Find N foldable phone is equipped with a 7.1-inch main display, adopts LTPO technology, has a 1Hz-120Hz adaptive refresh rate, and supports a resolution of 1792*1920 pixels. The mobile phone is equipped with the latest Qualcomm SnapdragonTM 888 mobile platform and Pixelworks' point-by-point semiconductor high-efficiency color calibration technology, which provides strong support for the presentation of high-quality visual effects on the folding screen.

Pixelworks’ point-by-point semiconductor visual display technology provides OPPO Find N with the following outstanding performance in terms of screen display quality (including folding screen and outer small screen):

Absolute color accuracy: The screen of each OPPO Find N foldable phone is factory calibrated with Pixelworks' patented display calibration technology, and its average Delta E<1, which means that the human eye cannot perceive any deviation from perfect color reproduction.

Professional brightness calibration: The human eye captures brightness in a disproportionate manner, and the light perceived by humans is often only part of the brightness captured by the camera. Therefore, when the display interprets the color of the original image and presents it on the screen, it often needs to perform gamma correction to respond to the characteristics of human vision, so as to be more in line with the real look and feel. Pixelworks' brightness calibration technology can maintain the gamma value at 2.2 in different color modes (displays with a gamma value of 2.2 can produce almost the best color and are used as a standard for graphics and video professionals) to ensure that the naked eye is on the screen The colors seen above are almost the same as those seen in the real world to ensure the precise expression of the original intent of the image.

Color correction under low brightness: Pixelworks' visual display technology can call 3D LUT for precise color calibration, from simple gamma value, color range and tracking error, to correction of advanced non-linear properties, color crosstalk, hue, saturation , Brightness, realize the control of the full three-dimensional color space, even when the ambient light changes, the color displayed on the screen is always natural and true.

Leo Shen (Shen Lei), general manager of Pixelworks’ point-by-point semiconductor mobile phone product division, said: “It’s great to participate in and witness the launch of OPPO’s first foldable mobile phone, Find N. The mobile phone market is highly competitive, and top players often need to continue to iterate and innovate. In order to maintain a competitive advantage, OPPO’s achievements in the imaging field are obvious to all, and the exploration of foldable screens and future scrolling screens is also deepening. We are honored to participate in the innovation journey of OPPOFind N and hope to make the best screen The visual experience is brought to every OPPO user."

Time to market

The newly released OPPO Find N smartphone will be officially launched on December 23, 2021.
