WiseChip logoWiseChip Semiconductor Inc (WSI) was established in 2005 in Taiwan. The company develops and produces PMOLED displays. In 2009 WiseChip acquired fellow PMOLED maker Univision.

Wisechip says it's the world's second largest PMOLED maker, and the company now enjoys a surge in PMOLED demand (we hear the same from other PMOLED makers). The company currently offers glass-based PMOLEDs ranging from 0.33" to 5.5". Wisechip also develops blue-light free candelight-style OLED lighting panels and is also commercializing ITRI's plasmon-coupled OLED technology.

In May 2020 we posted an interview with Wisechip's VP of R&D.

Wisechip to commercialize Hyperfluorescence TADF PMOLEDs by year's end

Hyperfluoresence TADF materials developer Kyulux announced a collaboration with PMOLED maker WiseChip to bring Hyperfluoresence TADF emitter based displays to the market by year's end. Wisechip demonstrated an HF TADF display at the TADF Workshop last week in Fukuoka, Japan.

The PMOLED display shown by Wisechip was a 0.96" monochrome yellow 128x64 one. The demonstration showed how much brighter (or more efficient) the Hyperfluoresence based display is compared to Wisechip's current fluoresent-based displays. The power saving is almost 50%.

New video shows Wisechip's flexible, transparent and candle-light OLEDs

Wisechip, the Taiwan-based PMOLED maker, demonstrated its new flexible and transparent PMOLED displays last week in a trade show in Germany. Embedded News TV interviewed the company's R&D manager and published the following video which also shows Wisechip's latest OLED prototypes.

On display at the trade show were two flexible OLEDs - a 1.8" monochrome 160x32 panel, a 1.36" monochrome 128x16 panel. Wisechip also has a 256 x 64 display. Wisechip also demonstrated a new transparent OLED for automotive applications and a round 1.07" 160x136 transparent PMOLED (this one was also on display last year). Wisechip's original plan was to start producing transparent displays towards the end of 2016, but apparently this is a bit delayed. We hear that the displays are nearing production though.

Wisechip demonstrate new flexible and transparent PMOLED prototypes

Taiwan-based PMOLED maker Wisechip announced it is developing transparent and flexible PMOLED displays last year, and the company has presented new prototype displays in a trade show in Germany last week.

Wisechip demonstrated three flexible OLEDs - a 1.8" 160x32 panel and a 1.36" 128x16 panel. Both are monochrome (white) panels as you can see in the photo above. The third display is a 256x64 one. The curvature radius of Wisechip's displays is 40 mm. The photo also includes a demonstration of a PMOLED display embedded in a credit card form.

Wisechip shows new flexible and transparent PMOLED prototypes

Taiwan-based PMOLED maker Wisechip is set to demonstrate its new flexible and transparent PMOLED displays. In August 2016 Wisechip announced that it is set to mass produce transparent PMOLEDs by the end of 2016.

Wisechip already unveiled a 1.07" 160x136 transparent OLED, and this time the company will show a 4.1" transparent OLED, with a transparency of 65% and a high brightness of over 3,000 nits. This display is aimed towards automotive HUD applications.

PitekPro launches a new 256x64 PMOLED character-replacement module

Taiwan-based PitekPro launched a new 256x64 monochrome white PMOLED display. According to the company, this display is aimed to replace 16x2 character displays (whether PMOLED ones, or competing LCD displays) so that device makers can upgrade easily from a character display to a graphic one.

The display is 2.08" in size (127 PPI) and is said to be easy to use. You can find more information over at the OLED Marketplace, our own comprehensive OLED catalog. Contact us if you want more details on this panel.

Here is Wisechip's new transparent PMOLED prototype

Last week Wisechip announced that it will demonstrate its new flexible and transparent PMOLED panels. Wisechip achieved a breakthrough in transparent OLED production, and mass production will begin by the end of 2016.

Above you can see Wisechip's new prototype. It is a round 1.07" PMOLED that features a resolution of 160x136. We do not have any more technical details, but Wisechip says it achieves "good transparency".

Wisechip to start producing transparent OLEDs by the end of 2016

Wisechip announced that next week it will demonstrate its new flexible and transparent PMOLED panels, at a tradeshow in Taiwan. The company says it has achieved a breakthrough in transparent OLED production, and mass production will begin by the end of 2016.

Wisechip did not reveal any details about these upcoming panels, only saying that the panels will feature "good transparency". Wisechip will also demonstrate flexible PMOLEDs with a bending radius of 60 to 40 mm.

Wisechip blue-light free OLED program update

Taiwan's PMOLED maker WiseChip Semiconductors licensed National Tsing-Hua University's blue-light free OLED lighting technology, with an aim to mass produce panels. Supported by the Taiwanese government, Wisechip aims to start mass producing those 1900K OLEDs within two years.

Today we have some more information on this interesting project. National Tsing Hua updates that they have now developed (together with Wisechip) a 2nd-gen lighting panel that features an efficiency of 70 lm/W and is 5x15 cm in size. The University has been awarded two OLED lighting awards (a Taiwanese golden-award and the IDA Lighting Design Award).

ITRI developed a highly efficient blue OLED emitter based on plasmon-coupled green PHOLED

Taiwan's ITRI research institute developed a long-lasting OLED blue emitter. The researchers used a green phosphorescent emitter with a new double metal structure - that emits a blue light. The so-called Plasmon-Coupled Organic Light Emitting Diode (PCOLED) structure's lasts 27 times as long as a blue fluorescent emitter.


The researchers explain that a regular green phosphorescent emitter always emits a very weak emission. By using the double-metal structure, more plasmons are generated which means a larger blue emission. This is not an up-conversion process - but merely a change in conditions within the green material. This condition was actually discovered by accident.
