Producers of flexible and punch-hole AMOLED displays fight for business

Producers of flexible and punch-hole AMOLED displays fight for business
Flat panel display producers in China are eager to start selling flexible AMOLED displays, and AMOLED displays with punch-holes, according to Digitimes. At this year's China Information Technology Expo 2019 (CITE), which wrapped up earlier this month, companies like BOE Technology, Visionox, Tianma Microelectronics, Everdisplay Technology and China Star Optoelectronics Technology (CSOT) displayed their flexible screens for use in foldable phones. Also showing off its flexible AMOLED panels was Royole, which uses the screens for its own foldable FlexPai smartphone.

All of these manufacturers are monitoring what is going on with Samsung and its Galaxy Fold device. Earlier today, the company delayed the U.S. launch of its foldable phone by at least one month due to issues with the interior display and the hinge. The Huawei Mate X outward folding device is expected to launch later this year. Other companies that could release a foldable phone in 2019 include Oppo, TCL, Motorola and Xiaomi.

Meanwhile, companies turning out smartphone displays in China are now offering punch-hole panels with resolutions as high as 1080p (Full HD). The punch-hole is a small opening punched into a display allowing a front-facing selfie camera to be housed inside a phone's screen. Some phones, like the Samsung Galaxy S10+, have two punch-holes in the screen for a dual selfie camera setup. The use of the punch-hole allows phone manufacturers to offer handsets with a high screen-to-body ratio and thin bezels without the use of a notch.

CSOT is said to be shipping through hole and blind hole panels to Samsung. The latter has a punch-hole that goes completely through the display to the other side, while the latter has a hole that is drilled down to a certain depth. The company also showed off its self illuminating displays, while Tianma exhibited a back-lit smartphone panel. Both of these depend on mini-LEDs as a source of light. These are light emitting diodes that are smaller than 100 micrometers.

If the punch hole display sales are successful, tear drop design might be the last notch we will see produced next year. Unibrow notch is now officially obsolete.

Mole displays still looks ulgy and also cut into the display like a notch Anyways these are all interim solutions until the endgame of the camera under the display

The galaxy s10 implementation is good. The s10 plus one not so

IMO they are both very average implementations Not bad implementations like the deep Pixel 3 XL or fat iPhone notches But they both still cut into the display similarly to small notches

Punch holes are better than notches and tear drop. There is a reason why everyone is trying to make punch holes now after the S10 series have used them so effectively.
