The competition for front fingerprint recognition of smart phones is expected to become hot.

In the smart phone with the existing home button, the front fingerprint sensor was installed on the home button. Fingerprint security enhances security, but recently, full screen Smartphone without home button has been released and fingerprint sensor has been moved to the back of Smartphone. This has caused disadvantages such as an uncomfortable hand shape when touching a finger to the fingerprint sensor and fingerprints on the camera lens.

In order to improve these points and to implement a complete full-screen Smartphone, the development of integrating full-screen fingerprint recognition with display is continuing.

The method of full-screen fingerprint recognition is largely examined by both optical and ultrasonic methods. The optics are inexpensive and easy to mass-produce, but the OLED substrate must be transparent because the sensor is to be located below the OLED panel. Therefore, it is applicable to rigid OLED using glass as a substrate, but it is difficult to apply to flexible OLED using colored PI as a substrate. The ultrasonic method is most stable in accuracy and durability, but it has a disadvantage of high manufacturing cost.

Currently, Chinese set makers have begun to launch smart phones with optical front fingerprint recognition. The Galaxy S10, which will be released next year by Samsung Electronics, is being watched for the adoption of ultrasonic full-screen fingerprint recognition. LG Display is also developing a display with front fingerprint recognition.

As such, the sales for full-screen smart phones with front fingerprint recognition are expected to be started in earnest. Competition in the smartphone market is expected to become more intense in the second half.

Samsung Electronics, Display Business division’s operating profit in the second quarter of 2018 was KRW 140 billion.

Samsung Electronics announced its sales of KRW 58.48 trillion and operating profit of KRW 14.87 trillion through the earnings conference call of the second quarter, 2018 on July 31. Its sales decreased by 4% YoY and the operating profit increased by KRW 800 billion. Sales decreased 3% QoQ and operating profit fell by KRW 800 billion QoQ.

According to Samsung Electronics, the display panel business recorded sales of KRW 5.67 trillion and operating profit of KRW 140 billion, due to slowing demand for flexible OLED panels and declining sales of LCD TV panels. Despite improved utilization of rigid OLED, OLED division’s earnings declined QoQ due to continued weak demand for flexible products.

Competition with LTPS LCD is expected to intensify at rigid OLED in the second half of 2019, but earnings are to improve on increased sales following the recovery of flexible product demand. Sales and operating profit are projected to improve in the second half on the back of production of flexible OLED for Apple’s new iPhone models from 2Q.

Samsung Electronics plans to expand its share of OLEDs for mobile devices by strengthening its differentiated technology and cost competitiveness, and to strengthen its capacity for new products such as foldable OLEDs. Samsung official said that foldable OLED will contribute to growth from next year rather than immediate performance in the second half of the year.

IT • Mobile (IM) division posted sales of KRW 24 trillion and operating profit of KRW 2.67 trillion. Operating profit fell 34.2 percent from KRW 4.06 trillion in the same period a year ago, and also fell sharply from the previous quarter (KRW 3.77 trillion). In 2Q, handset sales reached 78 million units, of which 90% are smart phones. 5 million units of tablet were sold. The average selling price (ASP) of the handsets is in the second half of US$ 220. The Consumer Electronics (CE) division posted sales of KRW 10.4 trillion and operating profit of KRW 510 billion in the second quarter of the year. Overall sales and operating profit of the first half of the year were KR W 20.14 trillion and KRW 0.79 trillion, respectively. TV profits improved thanks to robust sales of high value-added products such as QLED TVs amid the global sports events. On the other hand, SEC’s facility investment in the second quarter was KRW 8 trillion. By business, semiconductor area accounted for KRW 6.1 trillion and KRW 1.1 trillion was invested for display area. In the first half, a total of KRW 16.6 trillion was invested; including KRW 13.3 trillion in semiconductors and KRW 1.9 trillion in display.

LG Display, Showed OLED lighting for unmarried mothers

LG Display delivered 30 OLED lighting units, made by its employee volunteers, and baby products to 30 unmarried mothers.

This volunteer activity was carried out by the talent services of OLED lighting employees. OLED lighting business division donated 30 flexible OLED lighting panels, and the product planning team customized the lightings for breastfeeding for unwed mothers.

On July 27, the employee volunteers assembled light fixtures, which were customized by woodworking parts through social enterprises, and panels as finished products. In addition, various items needed for a baby and cheer letters for the unwed mothers were packed together. The packaged gift sets were delivered to 30 unmarried mothers living at the unmarried mothers’ facilities through the Eastern Social Welfare Society on July 30.

OLED lighting reduces light flickering and blue light, which affect eye health. And its mild light protects you from eye fatigue. It is also regarded as an eco-friendly product because it generates less heat and has no harmful substances. Since it is the organization that best knows the characteristics of OLED lighting, it suggested the service of delivering the OLED lighting for breastfeeding, made by its members, suitable for the baby-care environment.

Kim Yong-Jin, manager of the OLED lighting sales team who participated in the volunteer service, said “I feel it was worthwhile to deliver the OLED lighting directly to the necessary neighbors although I have dealt with it for business. When I see the neighbors who were delighted with little help, I have to think once again that service activity is so much fun.
