We have built a mini-projector with LED light sources that is sufficiently small for portable applications. The projector has a three-panel architecture with transmissive LCD micro-displays in order to combine a high lumen output with a low cost price. The volume of the light engine is 100 cc.

27.1: POB technology applied in Mini LED backlight
SID Symposium Digest of Technical Papers, 2022Today, with the rapid development of Mini LED backlight technology, what kind of technology can meet the needs of consumers, while the cost is controllable and can be accepted by the industry? POB are definitely such an option. POB do not require special transfer equipment at first and can be processed using current SMT machines. POB is superior to COB

An Active Matrix Mini‐LEDs Backlight based on a‐Si
SID Symposium Digest of Technical Papers, 2020Beyond LCD and OLED, mini‐LEDs and micro‐LEDs are expected to be a promising candidate for future displays. In this work, we fabricate an active matrix mini‐LEDs backlight based on a‐Si. The driving mechanism with 2T1C and process flow are discussed in detail. IR‐drop is analyzed and improved through several method because of the fact that high current

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.

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.

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.

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.

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 ...
