Samsung pushes ultra-high-definition VR screens to stabilize screen dominance

With the continuous development of VR technology and continuous penetration in all walks of life, but we all know that the biggest problem in the current VR is facing the display problem, VR devices for the display screen is particularly high, such as HTC Vive, PS High-end VR products such as VR and Gear VR have their own characteristics, but VR devices require very high resolution for display screens. Even if they can temporarily use OLED screens, the problems and visual effects are very poor. Producing a screen that specializes in supplying VR devices solves a lot of problems that arise when wearing VR devices.

Not long ago, Google and Sharp announced that they would jointly develop VR LCD screens. However, Samsung, one of the giants of the screen, took the lead and released the first dedicated screen for VR screens. According to the data released by IDC, this year it was recently displayed. Samsung still holds the first market share in the global VR market in the quarter.

At last month’s SID Display Week, Samsung demonstrated a 3.5-inch AMOLED display with 2024×2200 pixels. The pixel density is as high as 858ppi, and the maximum brightness of the screen is 100nit. This configuration enables the refresh rate to reach 90Hz. From a native point of view, this is a product that has more than three times the pixels of other products.

Even after experiencing the capital bubble of the previous year, VR is still the industry with the best prospects at present. There are still many companies actively doing R&D, but there are also some high-flying startups that are too anxious and have led to a capital bubble, the previous year’s “ VR winter theory: "Users who are conscious of VR products still remember, but I think that this year has entered the VR industry in a stable period. For companies that are single-minded to display giants, this year should be the time for the VR industry to flex its muscles.

3000W Three Phase AC Source System

Product Introduction:

APM 3 Phase Ac source SPS300VAC3000W is capable of delivering 3000VA of output power.3 Phase Ac Power Source is a 3-phase output programmable AC Power Supply which provides with high power density. With high speed DSP+CPLD control, high frequency PWM technology, active PFC design, It is able to provide not only stable DC/AC output power, but also 3-phase / 1-phase output. This AC power supply is featured with high power density, high reliability and high precision, meanwhile it possesses operation interface of touch screen and keys manually. It is able to analog output normal or abnormal power input for electrical device to meet test requirements, which is applicable to electric, lighting, aviation sectors, etc. It could be applied to enterprise`s production test as well.


Product Features:

● Large touch color screen, possess complete functions and easy to operate
