Visionox: What is the AMOLED pixel arrangement?

IT Home News on February 26, according to Visionox released, at the 2021 Visionox Innovation Conference, Visionox's Pixel Arrangement made its first public appearance, achieving the industry's highest visual equivalent pixel density and announcing that domestic AMOLED displays have taken a step towards high image quality.

On nearly 10 full-screen and folding screen mobile phones, Visionox Ding-type pixel arrangement has been successfully mass-produced, and "Ding-Pai" has gradually become well-known to the public because of its clearer, more uniform and more delicate display quality. Today Visionox officially brought relevant science.

What are the characteristics of the ding-type pixel arrangement? The arrangement of ding-shaped pixels in the microscope field of view is a combination of sub-pixels composed of isosceles trapezoids, which are similar to the side view of the continental Bronze Age ceremonial vessel, the Ding. The top pixel arrangement is hence the name.

Therefore, whether it is the secondary screen area and main screen area of the under-screen camera, or the full screen and folding screen, as long as the pixel arrangement meets the characteristics of "isosceles trapezoidal", regardless of the size and shape of the sub-pixel area, it belongs to the top-type pixel arrangement.

It is worth mentioning that this pixel arrangement is also conducive to improving the transmittance of the sub-screen area of the camera under the screen, thereby improving the photo quality of the front camera.

But why make a set of sub-pixels form an isosceles trapezoid? Visionox said the answer is hidden in the patent for the pixel arrangement design.

In 2016, Kunshan Guoxian Optoelectronics Co., Ltd. submitted an invention patent application for "AMOLED Pixel Structure and Display Device".

In the abstract of the patent application, the design idea of this pixel structure is proposed: the AMOLED pixel structure includes several first subpixels, second subpixels and third subpixels, and the third subpixel is B subpixels. The center of the two first subpixel luminous zones and the two third subpixel luminous zones located around the second subpixel luminous zone form a virtual isosceles trapezoid... Increased process margin.

Increasing the process margin means that from the beginning of the pixel arrangement design, the mass production is the goal. After obtaining the patent, Visionox began the process of introducing it into mass production. In addition to designing the structure between pixels, Visionox can also design a total solution with TFT and SPR algorithms based on customer needs and quickly import into mass production.

For example, Visionox's recently released 1Hz low-power Hybrid-TFT also uses a top-type pixel arrangement.

At present, the relevant patents arranged around the Ding-type pixels have not only been authorized in Chinese mainland, but also in Taiwan and the United States. In addition, Visionox has also laid out a patent family related to the pixel arrangement of the Ding-type.
