Summary of SONY RELEASES 0.5″ OLED MICRODISPLAY WITH 1600 X 1200 RESOLUTION
Sony's ECX339A is a 0.5-inch OLED microdisplay boasting the industry-leading UXGA resolution (1600 x 1200) with a 6.3μm pixel pitch. It features optimized transistor layouts, a new drive circuit operating at half voltage for low power consumption, and an original variation compensation circuit to ensure high image quality. The display supports up to 240 fps frame rates and utilizes a direct-deposited color filter on the silicon substrate to improve viewing angles. This technology targets high-end electronic viewfinders for cameras as well as AR and VR applications.
Parts used in the Sony ECX339A OLED Microdisplay:
- OLED display technology
- Miniaturization technology
- New drive circuit design
- Sony original driving system
- Optimized transistors layout
- Process for addressing uneven characteristics
- Sony original variation compensation circuit
- Color filter deposited directly on silicon substrate
Sony Corporation today announced the upcoming release of the ECX339A OLED Microdisplay featuring UXGA(1600 x 1200 resolution), the highest in class for a 0.5-type. This product achieves the world’s smallest pixel pitch of 6.3μm by leveraging Sony’s OLED display technology and miniaturization technology, enabling a resolution 1.6x higher than the previous model1. By employing a new drive circuit design that operates on half the voltage of the previous model1, the new product achieves the same level of low-power operation as its predecessor but with much higher resolution. When paired with Sony’s original driving system2, a frame rate up to 240 fps is supported—double that of previous product1.
Enhancing the resolution on microdisplays has traditionally presented problems such as deteriorating image quality due to decreased pixel pitch and inferior viewing angle properties. The new product features optimized transistors layout and process to address uneven characteristics and loss of withstand voltage, the issues associated with transistor miniaturization. The Sony original variation compensation circuit also enhances picture quality. Additionally, the color filter is deposited directly on the silicon substrate, reducing its distance from the light emitting layer, and the filter’s color array has been modified. This helps to secure the viewing angle properties while achieving high resolution.
OLED Microdisplays are widely used in digital camera electronic viewfinders (EVF) for their superior high contrast, high color gamut, and high-speed responsiveness. Sony, having achieved this high resolution and high frame rate, now offers even more realistic image display and accurate capture of subjects for use in high-end cameras that demand extremely high image quality.
Going forward, Sony expects this high-definition OLED Microdisplay to be employed in a diverse range of fields and applications such as AR (augmented reality) and VR (virtual reality) head-mounted displays.
