Sony 1.3-inches 4K OLED Microdisplay
Sony Semiconductor Solutions Corporation (SSS) continues to push the boundaries of display technology with its latest innovation – the microdisplay 4K OLED display, model number ECX344A. Measuring a mere 1.3 inches, this microdisplay is poised to revolutionize the world of augmented reality (AR) and virtual reality (VR) applications.
At the heart of the ECX344A is its impressive 90Hz refresh rate, ensuring smooth and lifelike visuals. Complementing this feature is an exceptional contrast ratio of 100,000:1, delivering vivid and true-to-life images. Enthusiasts of vibrant colors will also appreciate the microdisplay’s coverage of 96% DCI-P3 color gamut, enhancing the visual experience further.
One of the key advancements that sets the ECX344A apart is its “miniaturization process,” a technology Sony honed while developing electronic viewfinders (EVFs) for cameras. This process enables the microdisplay to achieve remarkable resolution and refresh rates in a remarkably compact form factor.
Sony’s commitment to excellence doesn’t stop there. The ECX344A boasts a peak brightness of up to 5,000 cd/m², effectively mitigating ghosting effects and enhancing the display’s overall performance.
A standout feature of the microdisplay is its “Scan Mode.” This unique display mode intelligently renders content at full resolution only in areas within the viewer’s field of vision. For peripheral or less focal areas, the resolution is subtly reduced. This ingenious technique reduces data transmission by a notable 60%, all while maintaining a truly immersive experience.
