Comprehensive Introduction to TOPLITE's VR Lenses and Compatible Displays

Although FAST-LCD currently holds the majority share in VR device installations, its primary drawbacks—large size and low brightness—lead to bulky optical components and heavy VR headsets, significantly affecting wearability. Miniaturization and lightweight design have become an inevitable trend for the next generation of VR devices. Our designed VR optical lenses are deeply adapted to the following OLED displays:

1. SeeYa 0.49-inch Display (OLEDoS)

This is an OLEDoS display with a resolution of 1920×1080 and a brightness of 1,800 nits. Currently, some AR and VR devices use this screen. We have developed three VR lens models adapted to this screen: V2, P2, and PW2. Among them, V2 is a five-element refractive imaging lens, while P2 and PW2 are Pancake-based imaging lenses.

The V2 lens is currently used in the CINESOLO V2 head-mounted display (HMD). CINESOLO is a rising VR HMD brand. The CINESOLO V2 uses the V2 lens and SeeYa's 0.49-inch OLEDoS screen, with a host weight of less than 110g. It is easy to wear and highly portable, supporting USB Type-C interface signal input, making it ideal for use with mobile terminals that output DP protocol signals.

P2 is a Pancake-based VR lens with features such as small size, thin thickness, light weight, and extremely low distortion (＜1.8%). When paired with this screen, the interpupillary distance (IPD) of the dual lenses can be as small as 46mm, making it suitable for VR products worn by children and special applications such as gun sights.

PW2 is also a Pancake-based VR lens, featuring small size, thin thickness (as low as 10mm), light weight (approximately 10g), and extremely low distortion (＜2%). When paired with the 0.49-inch screen, the field of view (FOV) can reach 64 degrees, making it suitable for movie-watching VR devices and bringing excellent lightweight and thin design to such products.

2. Sony/BOE 0.71-inch and SeeYa 0.72-inch Displays

Sony's 0.71-inch screen is a widely used Micro OLED screen on the market, with a resolution of 1920×1080 and a maximum brightness of 700 nits, commonly found in viewfinders of digital cameras and some XR movie-watching products. Toplite has developed the V1 lens to adapt to this screen, which uses a multi-lens refractive imaging solution.

CINESOLO V1 is a VR movie-watching HMD using the V1 lens. Thanks to the LVDS signal reception mode of Sony's screen, CINESOLO V1 can achieve built-in screen mirroring. Mobile devices and PCs (regardless of high, mid, or low range) can achieve wireless screen mirroring as long as they can access a Wi-Fi network and are on the same wireless local area network as CINESOLO V1. It is understood that Sony will also develop a high-brightness version of the 0.71-inch screen in the future.

SeeYa's 0.72-inch screen is an OLEDoS screen with a resolution of 1920×1080 and a maximum brightness of 1,800 nits. According to the manufacturer, it can already supply the market in small quantities.

For high-brightness 0.71-inch and 0.72-inch screens, we have developed two Pancake-based VR lenses, P1 and PW1. P1 will be positioned as an affordable VR lens with a FOV of up to 58 degrees and distortion less than 1.5%. PW1 has stronger performance, a wider FOV (up to 72 degrees), thinner thickness (as low as 12.5mm), lighter weight, and distortion less than 1.5%, suitable for lightweight and thin all-in-one VR devices integrated with light multi-sensors.

3. SeeYa 1.03-inch Display (OLEDoS)

SeeYa's 1.03-inch screen is a square OLEDoS display with ultra-high resolution (2560×2560) and maximum brightness of 1,800 nits, attracting attention from many VR developers. We have developed two Pancake-based VR lenses, P3 and PW3, to adapt to this screen. P3 is positioned as an economical Pancake lens with a FOV of 60 degrees and distortion less than 1.4%.

(P3 Lenses)

PW3 is positioned as a Pancake lens for professional-grade all-in-one VR devices, featuring a wider FOV (95 degrees), thin thickness (13.5mm), light weight, and distortion less than 1.8%, bringing more lightweight and thin design to multi-functional professional all-in-one VR devices.

Among the series of VR lenses developed by Toplite, V1 and V2 have completed mass production readiness and will soon be available for bulk supply. P1, P2, and P3 are already available in small batches, and PW2 can provide test samples.

Currently, the high-brightness version of Sony's 0.71-inch screen has not yet been released, and BOE's 0.71-inch and SeeYa's 0.72-inch screens have not entered mass production. Given that PW1 lens production requires significant mold development costs, PW1 lens samples cannot be provided to the market for now due to the inability of screen suppliers to deliver normal shipments. We look forward to more suitable mass-produced screens for adaptation.
