Sony today, May 28, has announced a soon-to-release of Sony ECX339A Microdisplay OLED that features a UXGA resolution of 1600 x 1200, the highest in class for a 0.5-type.
Thanks to the technologies of OLED display and miniaturization of Sony, the Microdisplay can offer a pixel pitch of 6.3μm, the smallest ever in the industry. It enables a resolution of 1.6x higher than its predecessor model.
There’s a new drive circuit design employed aimed to operate on half the voltage of the predecessor, allowing for the same level of low-power operation for the new Microdisplay while putting a higher resolution on the table. It also supports 240fps, that’s double the predecessor.
The Microdisplay additionally features optimized transistors layout and process as a solution to uneven characteristics and loss of withstand voltage, leading to deteriorating image quality. The original variation compensation circuit of Sony helps enhance picture quality as well.
Furthermore, the color filter in the Microdisplay has been deposited directly on the silicon substrate. This reduces the distance between the filter and the light emitting layer. Also, the color array of the filter is modified. This will be useful to secure viewing angle properties when achieving high resolution.
The Sony OLED Microdisplay will find purpose in digital camera electronic viewfinders (EVF), offering superior high contrast, high color gamut, and high-speed responsiveness. The high frame rate and the high resolution will be ideal for high-end cameras demanding extremely high image qualities.
Sony wants to deploy the product in a ‘diverse range of fields and applications like AR and VR head-mounted displays. The company has planned for mass-production shipment in November 2018, with a sample price of 50,000 Japanese Yen without taxes.
