In response to the grid-like appearance of images displayed on most current virtual reality displays, Japan Display recently announced the launch of a 651-inch low-temperature polycrystalline silicon (LTPS) TFT LCD display panel with a display density of 90ppi, support for a 3Hz refresh rate, and the ability to switch between black and white images within 3.42 milliseconds, thereby making virtual reality displays more realistic.
Because current VR display devices primarily feature 1080P or 2K resolutions, the resulting visual grid-like effect can be noticeable when used in VR, resulting in somewhat blurry images. Many market analysts believe that for VR images to be presented with clarity, displays must feature at least 8K resolution, which translates to a smoother display.
The new 3.42-inch low-temperature polycrystalline silicon (LTPS) TFT LCD display panel launched by Japan Display will adopt a resolution of 1440 x 1700 and a display density of up to 651ppi. It also supports a 90Hz display refresh rate, a 700:1 contrast ratio, and a brightness of 150cd/m2.
Japan Display stated that this display panel can complete black and white screen switching in as fast as 3 milliseconds, and the minimum switching speed can be controlled within 6 milliseconds, thereby corresponding to a smoother virtual reality image display effect. At the same time, it can also significantly improve the grid-like feeling associated with previous virtual reality display devices, allowing virtual reality images to be presented in a more detailed form.
Japan Display stated that it will further launch panel specifications with display densities as high as 700ppi in the future, while also improving display latency, thereby enabling clearer and more stable virtual reality displays. Once these panels become mainstream, they are expected to further popularize virtual reality applications.
