Samsung shows how its LCD TVs compare to LG's OLED TVs in terms of image retention

Oct 16, 2017

Samsung has published a video showing how 12 hours of gaming effects different TV technologies. Samsung compare's it's own Q-LED (quantum-dots enhanced LED LCD TV) with LG's OLED TVs (the 2017 OLEDB7).

The video shows that following the extensive gaming run, Samsung's TV shows no image retention (burn-in), while some problems are clearly visible on LG's TV.

Facebook launches the affordable Oculus Go VR headset with a fast-switch LCD

Oct 14, 2017

Oculus (Facebook) announced its new affordable VR headset, the Oculus Go. This $199 device will launch early next year for $199 and Facebook hopes that this will be a step towards its goal to get one billion people to use its VR products.

One of the ways that Oculus used to lower the cost of to Go headset is to switch from an OLED to an LCD. Oculus says that this is a "fast-switch LCD". It's too early to say how this display will compare to the current OLED used in the Oculus Rift. Looking at the slide above, it seems that the Go uses a single 2560x1440 LCD.

Is Samsung looking at Micro-LEDs for its next-gen premium TVs?

Oct 11, 2017

A report from Korea suggests that Samsung is accelerating its effort to develop a Micro-LED based TV. The company is currently focused entirely on QD-LEDs for its premium TVs but is looking for alternative technologies as it fails to increase its market share in this segment.

Samsung is said to be looking at several alternatives - one of which is to acquire Taiwan-based PlayNitride - a deal that was first reported on OLED-Info in April 2017. Samsung aims to first use micro-LED technologies for its cinema LED screens, and then apply it to home-based TVs as well.

Valve says that recent advances in LCDs bring it up to par with OLED displays for VR applications

Oct 11, 2017

US-based video game developer Valve has announced that it will license more of its VR technology to hardware makers that can develop VR HMDs based on its technology. In addition to the tracking and input tech that was already licensed before, HMD makers can now use Valve's optical system, calibration tools and a supporting software stack.

Currently pretty much all high-end HMD devices adopt OLED displays as these panels offer faster refresh rates compared to LCDs. But Valve says that recent LCD advancements combined with VR specific calibration now make LCD a viable technology choice for high end VR systems.

Smartkem and a leading OLED maker in China to co-develop and commercialize OTFT-based LCDs and OLEDs

Oct 04, 2017

UK-based OTFT developer SmartKem announced that it has signed a letter of intent (LOI) towards a commercialization partnership with a leading OLED market in China. This partnership will enable the development and industrialization of OTFT LCDs and OLEDs on plastic substrates.

SmartKem says that this LOI is just the first step in a joint commitment by SmartKem and the OLED maker to develop LCD and AMOLED solutions and a full commercialization of an OTFT-based display production.

CPT aims to start mass producing QD-LED displays within 2 years

Sep 26, 2017

Taiwan-based Chunghwa Picture Tubes (CPT) says that it is developing Quantum-Dots displays (QD-LEDs) produced using a printing process. CPT says that QD-LEDs offer pure-colors, long lifetime and are more efficient and stable compared to OLED displays.

CPT hopes that a printing process will enable low cost QD-LED displays. CPT's Material Technology Division manager estimates that the major obstacles have already been overcome - although the performance of quantum dots is still lacking and CPT is continuing to research and develop QD materials. CPT estimates that it could start mass producing QD-LED displays within two years.

Are Micro-LED displays coming sooner than expected?

Sep 10, 2017

Digitimes posted an interesting story, quoting PlayNitride's CEO that says that Micro-LED displays are easier to produce than people estimate. The company hopes to start mass producing such displays in the second half of 2017.

In PlayNitride's R&D setup, it takes about 10 seconds to transfer and place 200,000 LEDs - which means that a 5" panel will take only 10 minutes to produce. The yield rate at the company's setup is over 99%.

OLED prices are dropping as cheaper LCDs flood the smartphone display market

Sep 01, 2017

An interesting report in Business Korea discloses that the price competition between high-end LCD and rigid (glass-based) OLED displays is intensifying. Both LCD and OLED display makers are struggling to win orders from low-end and mid-range smartphone makers, and as a result prices are declining.

In 2016 several new LCD plants have started operations ,which resulted in a large increase in LTPS LCD capacity - and thus lower prices. BK states that a smartphone LCD is now around 5$ cheaper compared to an OLED, which puts pressure on SDC and other AMOLED producers to lower prices.

IHS and DSCC seem to disagree on the future of QLED-LCD TVs

Aug 26, 2017

According to IHS, sales of quantum-dot enhanced LCD TVs, or QLED TVs, dropped 48% in Q2 2017 compared to Q1 2017. Total sales in Q2 amounted to only 351,000 units - down from 671,000 in Q1 2017. OLED TV sales, meanwhile, increased from 29% from 212,000 units to 282,000 units.

Following this report, Business Korea speculates that Samsung Electronics may have to change its premium TV strategy, as it faces market share lose in this very important segment and may lose its leading position in the total TV market.

MicroLED-Info, a new knowledge hub to focus on Micro-LED displays

Aug 16, 2017

We are happy to announce a new Metalgrass knowledge hub, Our new site will focus on Micro-LED display technology and its future market. MicroLED is quickly becoming a promising future display technology.

Many expect the first Micro-LED devices to hit the market in the very near future, with first applications in the wearable market - and also in HUDs and HMDs. MicroLED promise great performance, very high efficiency and brightness - and may indeed compete with OLEDs in the future. There are still many technical challenges ahead, but this is certainly a technology that any display expert should not ignore.
