CPT (Chunghwa Picture Tubes) was established in 1971 in Taiwan and was a CRT and LCD display maker.
In 2012 CPT started to develop AMOLED technologies and the company established a small-size experimental line. Later on CPT actually started to produce AMOLEDs in low volume, and also developed flexible OLED technologies.
In September 2019 the company filed for bankruptcy.
The latest CPT OLED news:
Chunghwa Picture Tubes (CPT) had some pretty interesting prototype OLED displays shown at the Touch Taiwan 2014 trade show last month. We do not have any information regarding how close are these prototypes to commercialization.
So first up is a flexible AMOLED display. This panel is 4.8" in size and 720x240 resolution (158 PPI). The company did not reveal any more technical details. The company also showed some simpler flexible PMOLED panels, demonstrating their sealing capabilities by immersing them under water (see image below).
In 2012 we reported that CPT (Chunghwa Picture Tubes), a Taiwanese LCD and CRT producer, started developing AMOLED panels and established a small-sized pilot line. Today our sources indicate that the company actually started small scale AMOLED production. I don't have a lot of information on CPT's line at this stage.
AIV-BEX also announced that a delegation from the company visited CPT's AMOLED line earlier in October. It seems that the two companies are in talks about a possible technical collaboration. AIV-BEX plans to construct a 4.5-Gen line that uses Oxide-TFT backplanes (CPT is also developing this technology, although the current production line is not using iGZO) and ink-jet printing for the organic material deposition AIV-BEX's line will have a monthly capacity of 30,000 sheets and the plan is to begin production in 2014.
CPT is using a 0.5" 800x600 (SVGA) microdisplay with a display area of 10.13x7.61 mm. It simulates a 15" display from 2.5 meters. As far as I know OLighTEK (a Chinese-based OLED microdisplay maker) is the only company that ships 0.5" SVGA OLED microdisplays so it is likely that they are the display supplier. CPT is also developing AMOLED displays, but as far as I know they do not produce OLED microdisplays.
There are reports that CPT (Chunghwa Picture Tubes) has setup a small-size experimental line for AMOLED panel production development. We do not have more information about that line or CPT's OLED program yet.
