Samsung Electronics is expected to release a smartphone next year with Samsung Display's OLED panel with Under Display Camera (UDC) technology. The equipment that implements UDC is called 'HIAA2 (Hole In Active Area)'.
Samsung Display decided to receive the first HIAA2 equipment at the A4 plant in Asan Campus, Chungnam, this month. The company plans to bring in mass production facilities early next year. The A4 plant has two 6th generation (1500mm × 1850mm) OLED production lines. The production capacity is 30,000 sheets per month based on substrate input.
HIAA1 equipment has already entered the first stage investment (phase 1) equipment in Asan 2 Campus A2 factory. I plan to bring in additional quantities. Samsung Display imported HIAA1 equipment in August this year and started mass production testing.
According to domestic market research company UBI Research, the production capacity of 5.5 generation (1300mm × 1500mm) rigid-flexible OLED line installed in the A2 plant is 194,000 sheets per month. It is 144,000 rigid OLEDs and 50,000 flexible OLEDs.
HIAA1 equipment and HIAA2 equipment mass production test time difference is 2 months. Entered A2 and A4 plants respectively. Both HIAA1 and HIAA2 instruments are equipped with a Philoptics laser system in the Wonik IPS vacuum chamber. When Phil Optics, which received an order from Samsung Display, delivers the laser system to Wonik IPS, it is reported that Wonik IPS will be attached to the vacuum chamber and delivered to Samsung Display.
HIAA1 is a dedicated 'hole display' device that drills the front camera hole within the OLED screen frame. Samsung Display could make a hall display without the HIAA1 equipment but had to dig a hole for each process step. The production cost can be lowered.
UDC is known for making transparent displays only in-camera apertures. Compared to not going through the display, the key is to reduce the distortion of light entering the camera lens. Research and development are underway to reduce the number and size of pixels and increase substrate transparency and transparency. Polyimide (PI), a substrate of the existing flexible OLED, is not transparent but has a yellowish tinge.
HIAA2 is a device that drills a lot of small holes using a laser in the camera hole of the display. In the process, it is referred to as laser etching (etching). It increases the transmittance of light.
Samsung Display is planning to bring in mass production facilities in early next year after wearing HIAA2 equipment this month.
Usually, Samsung Electronics has been using the best and latest technology in the Galaxy S series, a premium smartphone, and then spreading it to other smartphones. Hall Display OLED was first applied to the Galaxy S10 released in the first half of this year and expanded to Galaxy Note 10 in the second half.
However, Samsung Electronics is launching the foldable phone Galaxy Fold, which is higher than the Galaxy S this year, and it is also observed that the first target of UDC technology will be the next foldable phone. The introduction of HIAA1, a dedicated device, will increase the output of hall display, while UDC display, which has a low level of difficulty, will be applied to foldable phones produced in small quantities.
The industry believes that the implementation of UDC requires not only to display technology but also camera algorithm technology. The software compensates for yellow and blurry images.
The color of the image on the camera changes to yellow unless a transparent substrate is used. In addition, as the light transmittance decreases through the display, the blurring of the camera image is difficult to avoid. The development of front camera technology is needed at the same time, and the production cost will go up.
Yang Byung-deok, managing director of Display Development Group, Samsung Electronics, said earlier this year at the Galaxy S10 Display Technology Briefing that "the level of camera holes is not visible at all is not possible within a year or two." A senior official at Samsung Display said on the 16th, "The decision made by Samsung's wireless business division" was a question about the possibility of next year's UDC display-enabled smartphone.
