  • Patent number: 11489529
    Abstract: A semiconductor apparatus receives a first clock signal and a second clock signal. The semiconductor apparatus configured to perform a training operation internally, the training operation being an operation of internally correcting a phase difference between the first clock signal and the second clock signal by dividing the first clock signal to generate multi-phase signals, detecting phase difference between the second clock signal and the multi-phase signals, and adjusting phases of the multi-phase signals according to a result of the detecting of the phase difference.

  • Publication number: 20220231236
    Abstract: The present disclosure relates to an organic compound having the following structure of Formula 1, an organic light emitting diode (OLED) where an electron transport layer and/or a charge generation layer includes the organic compound and an organic light emitting device including the organic light emitting diode. While only the specific moiety in the organic compound is deuterated, the organic compound can implement excellent luminous efficiency and luminous lifespan as a compound where all the carbon atoms are deuterated. The OLED can maximize its luminous efficiency and luminous lifespan with minimizing utilization of expensive deuterium.

  • Patent number: 11384915
    Abstract: A garnishless type hidden lamp applied to a vehicle, may include a light source module, in which an internal lens spaced from an external lens, appearing as a garnish from outside thereof due to a color of a penetrable painting portion which reflects the external light, with an air gap interposed therebetween transmits an internal light of a light source through laser perforation holes to form a laser pattern on the external lens, so that the garnishless type hidden lamp may have the sense of unity with vehicle design by a painting garnish function of the external lens without combination with a separate metal garnish, improve a wow effect using the painting garnish, implement differentiated and customized lighting by only changing the laser pattern.
