JDI has unveiled a 4K x 4K IPS LCD microdisplay achieving the world’s highest 2527 ppi resolution for virtual and mixed-reality headsets on a glass substrate. The 2.15 in. microdisplay utilizes LTPO (low-temperature polycrystalline oxide) and COA (color filter on array) to help reduce power usage while giving users a better virtual image with less visible pixelization.

JDI has unveiled a 4K x 4K IPS LCD microdisplay that achieves the world’s highest 2527 ppi resolution for use in virtual and mixed-reality headsets on a glass substrate. The 2.15 in. microdisplay utilizes LTPO (low-temperature polycrystalline oxide) and COA (color filter on array) to help reduce power usage while giving users a better virtual image with less visible pixelization. The display was awarded the DIC International Display Technology Innovation Award on June 18.

VR/MR headsets depend on microdisplays mounted close to the eye to create the illusion of a virtual reality. The resolution of each display affects the clarity of the virtual world, and low-resolution displays suffer from visible pixelization that detracts from the sense of VR realism.

For a rough sense of what VR users would see, a 24-inch 1,920 x 1,080 monitor has 92 pixels per inch. When the 3,840 x 3,840 JDI display is used to create a 40-inch virtual view, users see images with similar clarity at 96 ppi.

By eliminating the use of more expensive silicon substrates, the JDI glass substrate display opens the door to inexpensive, high-resolution VR/MR headsets. Pricing and availability have not been announced. Readers who can’t wait to jump into the metaverse can always buy a lower-resolution VR headset on Amazon in the meantime.

Develops World’s Highest Resolution (>2500 ppi) Ultra High-Resolution VR Display on Glass Substrate – Awarded DIC International Display Technology Innovation Award –

JDI has developed the world’s highest resolution ultra high-resolution display on a low-cost glass substrate (2.15 inches, 2527 ppi) for use in virtual reality head-mounted displays (VRHMDs). JDI’s technology breakthrough makes possible affordable VR displays with the extraordinary imaging and highly realistic, immersive user experiences that were previously only available on high-cost silicon substrates.

Recognizing the importance of this technology, JDI was awarded the DIC International Display Technology Innovation Award on June 18, 2024, ahead of the July 3, 2024 start of Display Innovation China EXPO 2024 (DIC EXPO 2024, Shanghai), China’s leading display technology exposition.

In order to enhance the immersive experience when using a VR-HMD, it is important to secure a wide field of view (FOV) and eye-box (the range of eye movement where the screen can be viewed without distortion) in addition to a clear and natural image.

JDI's newly developed 2.15 inch, 2527 ppi ultra high-resolution display combines JDI’s worldleading LTPO (Low-Temperature Polycrystalline Oxide) and COA (Color Filter on Array) technologies to achieve a resolution of 3840×3840 pixels per eye, thus allowing for a wide FOV within a compact 2 inch display.

JDI’s ultra high-resolution LCD also minimizes the “screen door effect” problem withconventional VR-HMDs (in which pixel patterns become unintentionally visible to the user), thus providing a cleaner and more realistic visual experience. The significant cost advantages of using glass substrate for JDI’s ultra high-resolution display will cater to a broad range of needs within the high-resolution display market.

JDI will continue to leverage its world-leading technology capabilities to build upon its lead in the global VR display market.
