In order to give priority to this wave of VR battle cards, Google found a joint research and development of Sharp, hoping to use Sharp's technology to replace the OLED panel with existing LCD panels as a technology for AR/VR display panels. Solve the problem of tight supply of OLED panels.

Slay (Society for Information Display), currently held in Los Angeles, USA, Clay Bavor, vice president of Google's VR business, said in the forum that Google and Sharp jointly developed high-speed reactive LCD panel technology for use in the VR/AR field.

Google's VR platform Daydream and VR drawing app's Tilt Brush, location tracking technology WorldSense and other methods to introduce the use of AR / VR. At present, due to the current VR biggest problem, due to the inconsistency between the picture delay and the depth of field, the user may experience dizziness when viewing.

Since Google previously chose to use OLED production in Google Pixel Phone, but due to the shortage of OLED panels, and high-quality OLED panels, and then invest together with Sharp, how to use LCD panels to achieve response speed and image quality requirements A technology comparable to OLED panels.

It is not easy to replace the OLED with the existing LCD panel. It is still the congenital problem of the LCD panel, and the response speed is not as good as that of the OLED. Therefore, various manufacturers are also actively investing in research and development, hoping to make products comparable to the OLED speed. .

In fact, optimistic about the needs of VR (Virtual Reality) and AR (Augmented Reality) applications, each factory is actively investing in the layout, and the demand for VR devices will become a new product in the future, but the supply of components such as OLED panels Insufficient fear will affect the shipment of general VR devices. Among them, the shortage of OLED panels has become the biggest bottleneck for promoting AR/VR.

The demand for VR is hot, but the problem of severely insufficient capacity of OELD panels has made it impossible for brands to produce enough products to meet the needs of consumers. As VR application demand is higher than expected, the demand for OLED panels is pushed up by the market, and smart phones are actively introducing OLED panels, which makes the OLED out-of-stock problem more serious and affects the supply of VR products.

Previously, Google’s Daydream View smartphones use OLED panels, and Apple expects to launch OLED panels in the second half of this year. The entire market is actively investing in OLED products, making OLED panel supply tight, so the next VR device supply is insufficient. The situation may not ease.

Since the mobile phone is placed in the VR helmet, the messenger will see the right image when the first turn, so the panel response time is very important, otherwise there will be dizziness. Although the problem of picture lag can be solved by using the fast response characteristics of OLED displays, VR is used in place due to the shortage of OLED panels.

The market-adjusted unit IHS estimates that the shipments of global smart phone virtual reality devices this year will even drop 14.23 million sets, and the annual demand will decline by 23.8%.

Google and Sharp have partnered to develop low-latency LCD technology with specifications and quality that include less than 6 seconds of display technology and no need for backlighting, and reduce blurring, with transmission speeds of 50G to 100G per second.

The technology is more than twice as large as the current one, with more than 20 million pixels per pixel. It is also a power-saving technology with IGZO and a high-definition picture, which is superior to the power consumption and color fading of OLED.

Nowadays, Google and Sharp have developed such technology as an application panel that replaces OLED deficiency. It is equivalent to announcing that LCD can be used on VR, and also solves the problem of supply chain of new generation Android mobile phone technology and OLED panel.
