Mini-LED displays pixel circuit design
2020 IEEE International Conference on Consumer Electronics - Asia (ICCE-Asia), 2020SUMMARY In this paper, mini-LED displays pixel circuit structure having a plurality of current driven pixel groups, including a voltage controlled current source pixel circuit with a threshold voltage compensation design implemented with mini-LED driving, is proposed. The circuit in mini-LED display driving does not require lots of additional circuits,

Birefringent light‐shaping films for mini‐LED backlights
Journal of the Society for Information Display, 2020AbstractBirefringent light‐shaping films (BLSFs) for mini‐LED backlit liquid crystal displays (LCDs) are proposed and experimentally demonstrated by passive polymer‐dispersed liquid crystal (PDLC) films. Such films show angle‐selective scattering properties, achieved by proper material engineering and good vertical alignment of liquid crystals.

LED mini-lidar as minimum setup
SPIE Proceedings, 2014The LED mini-lidar has been designed and demonstrated as the near range atmosphere monitoring, dust and gas detections. The LED lamp is used as a lidar light source. It is not a special one, and just used as a small status indicator or a spot luminaire.

LED mini-lidar for air and dust monitoring
SPIE Proceedings, 2013LED mini-lidar is a new concept optical sensor, not to be replaced from the traditional lidar with laser light source. To use this lidar in near range, several lidar parameters were rearranged due to the new concept. LED device is tough against rough treatment. It has wide color variation including NUV and NIR regions.

Prospects and challenges of mini‐
AbstractWe review the emerging mini/micro–light‐emitting diode (LED) displays featuring high dynamic range and good sunlight readability. For mini‐LED backlit liquid crystal displays (LCDs), we quantitatively evaluate how the device contrast ratio, local dimming zone number, and local light profile affect the image quality.

Emerging high-dynamic-range mini-LED displays
Advances in Display Technologies IX, 2019We introduce mini-LED as a promising solution for high dynamic range displays. For mini-LED backlit local dimming LCD, we build a model to simulate the displayed image quality. Through modeling and subjective experiments, we demonstrate that the annoying halo effect could be suppressed to an unnoticeable level by appropriately choosing local dimming ...

Microcirculation imaging with multicolor LEDs and mini CCD camera
2013The microcirculation is defined as the smallest vessels where gas and nutrient are exchanged with tissues. In treatment of critical care, it is desired to monitor microcirculatory dysfunction to feedback it. The recent development of new imaging modalities such as Sidestream Dark Field (SDF) imaging has helped to directly investigate microcirculation ...
