Hisense HZ65U9E ULED XD, currently only available in China. Price-wise, Hisense is aiming to be cheaper than OLED, though probably similar-to or more than higher-end LCDs. For reference the
Learn about the difference between the two main techniques of illumination used in stereo microscopy: On the one hand, fiber optic illumination and cold ligh
The answer is the double-ended LED lamps. It’s safe-to-install and will save on labor costs, giving the double-ended LED lamps the edge over its single-ended counterpart. Double-ended LED lamps may be better suited as fluorescent replacements than single-ended LED lamps, it doesn’t mean that single-ended LED lamps are not also a viable

เทคโนโลยีมันพัฒนาไปเรื่อยๆครับ Full RGB จริงๆมันคือ LED แท้ๆครับ ไม่ใช่ทีวี LCD with LED backlight (ใช้แค่หลอด led สีขาวเป็น backlight) เหมือนทุกวันนี้

We’re talking about LEDs as small as 0.008-inch (200 microns) across. Using tiny light sources gives the display a lot more granular control over the brightness levels and color output. By

Direct Lighting. Indirect Lighting. Direct lighting illuminates a particular object or area. Indirect lights diffuse to lighten a large area. The maximum (up to 90%) light is directed downward in direct lighting. Maximum (up 90%) light is directed upwards in indirect lightning. Direct lighting creates a hotspot.

When buying T8 Tubes, it’s important to know exactly what you’re buying and why. When it comes to choosing between purchasing a T8 Tube with either Single-Ended or a Dual-Ended Connection, it comes down to your fixture and installation needs. Single-Ended Connection When installing a single-end powered LED tube, only one side of the tube’s pins will be energized or “live”. The other
Mini LED, on the other hand, uses a backlight that shines light onto a colour filter, creating what’s seen on screen. Because it uses smaller LEDs than conventional LED screens, its screen can
The light emitting diode is the most visible type of semiconductor diode. They emit a fairly narrow bandwidth of either visible light at different coloured wavelengths, invisible infra-red light for remote controls or laser type light when a forward current is passed through them. The “ Light Emitting Diode ” or LED as it is more commonly mUzte.
