Fingerprint Sensor

https://korean-electronics.com//inquiryCrucialTec recently announced that its subsidiary Canvasbio developed a fingerprint sensor, CB2400, which is optimized for the sides of smartphones.
This product is characterized by a 2.2 mm decrease in its width, which enables the product to match the slim sides of smartphones. Recently, smartphone makers tend to minimize the sizes of home keys and speakers in order to maximize the smartphones’ front screens. A design trend is gaining pace whereby smartphone makers aim to implement full-screens for smartphones. Therefore, an attempt is being made to move fingerprint sensors, which were till now located on the fronts of smartphones to the backs or sides. CrucialTec fingerprint sensors are made for the smartphones’ sides.
A CrucialTec spokesperson remarked, “Side fingerprint recognition is advantageous in maximizing battery spaces while increasing the sizes of front screens even though it faces space limitations due to slimmer mobile phones, and the accelerated adoption of curved glass. As we have the experience of producing fingerprint recognition modules for the sides of smartphones in Japan and China, we will sharpen our business competitiveness by combining sensors and modules.”

Vibration Motors& Rectangular Linear Vibration Motor

https://korean-electronics.com//inquiry[INQ. NO. 1806E31] The vibration motor of YOUNG JIN HI-TECH is widely adopted in small devices requiring long-time vibration, such as smartphones, wearable devices, game machines, medical equipment, toys, etc. In order to enhance competitiveness of the vibration motor, the company applied the structural new technology at the development stage, securing price competitiveness by simplifying the manufacturing process, and retaining uniform quality by applying process automation.
Linear Vibration Motor generates resonant vibration by stimulation of the electromagnet force with the natural frequency of the moving assembly including weight (vibration by moving the spring within the elastic range). The electromagnetic force is formed by direct winding on the yoke, and the magnetic stop function speeds up the response and solves small vibrations.
The Brushless DC Vibration Motor adopts the method driven not by mechanical switching but by electric switching using IC (Integrated Circuit, a kind of semiconductor device). It can be used permanently and maintenance is easy. Precise speed control by the PWM method is also possible. Both electrical and mechanical noise can be minimized. It has a miniaturized structure.
The Rectangular Linear Vibration Motor is a vibration motor that has improved the vibration sensation by installing a weight inside and then vibrating it left and right. The electromagnetic force of symmetrical structure is formed. The fast-response characteristic is implemented through the relative magnetic structure. The square structure of the product is easy to handle and minimizes vibration noise.
Established in 1997, YOUNG JIN HI-TECH, has been maintaining its integrity and challenging spirit for 21 years as a local SME based on the corporate philosophy of “Do it right now,” “Be sure to do it,” and “Do it until you achieve.” We produce advanced automation equipment requiring cutting edge technological prowess, such as smartphone, semiconductor, LCD, etc., and have been striving to create added value of the local community. In addition, we export the automation facilities to China, Vietnam, etc.


In particular, YOUNG JIN HI-TECH has accumulated know-how through ceaseless research and development centered on the institute of technology and, as a result, developed and registered a patent for a small vibration motor. Based on this, YOUNG JIN HI-TECH succeeded in commercialization and mass-produced the products in Vietnam, exporting them to Japan, China, etc. YOUNG JIN HI-TECH started the small motor business in 2010, received a presidential citation on Trade Day in 2013, was appointed as a “global hidden champion,” and as an excellent creative and innovative enterprise, received the Industrial Technology Award from the Minister of Trade, Industry and Energy, and was appointed as the Korean Master Technician in 2014, and was appointed as the enterprise of the month in 2015, thereby proving its technology and credibility.

Samsung Galaxy S9 Makes a Single Outing at MWC 2018

https://korean-electronics.com//inquiryThe Samsung Galaxy S9 was unveiled at MWC 2018 held on the Feb. 26-March 1 in Barcelona. In particular, this new Samsung Galaxy S series outshone all others since major smartphone makers such as Huawei, LG, and Xiaomi did not release new smartphones for MWC 2018.
The main features of the Samsung Galaxy S9 include the 5.8” (Galaxy S9) and 6.2” (Galaxy S9 Plus) Infinity curved QHD Super AMOLED display, super speed dual pixel camera (OIS, F1.5 / F2.4) and dual pixel camera (S9 Plus) with a resolution of 12 megapixels, 10-nano AP, and 4GB (S9) / 6GB (S9 plus) of DRAM. The Samsung Galaxy S9 will be mounting three different storages: 64GB, 128GB, and 256GB.
Overall hardware specs are not much different from the previous model. Yet, its improved camera functions and enhanced Augmented Reality (AR) functions such as AR Emoji are recognized as impressive. In particular, the camera is equipped with a super-speed dual-pixel image sensor along with a variable aperture capable of switching between F/2.4 and F/1.5, which allows taking brighter pictures in the dark, and dedicated DRAM, thereby providing a super-slow-motion mode that can shoot videos at 960fps (previously at 240fps).
Other features include AR Emoji, an animated emoji created by using one’s selfies that replicates the movements of a user’s face, available via AR shopping provided in collaboration with major brands such as Sephora, and AR live translation to read and translate words from photos.
In addition, intelligent scan that combines facial recognition and iris recognition and Dolby Atmos dual stereo speakers from AKG, a premium audio brand of Harman, are also emerging as successful upgrades on the previous model.
A representative of NH Investment & Securities explained, “Despite its relatively low sales volume forecast, the Samsung Galaxy S9 is expected to be able to bounce unexpectedly. It is because we believe that the competition will weaken due to lack of competition, the return of the replacement cycle of Galaxy S series (in odd numbers) every two years, and Samsung Electronics’ strengthened promotions will be unexpected variables to come.”
