Q: What does LED backlight mean? What are the advantages?
A: Since 2008, LED backlights have gradually entered industrialization and their market share has been expanding. From the beginning to the application of notebook computers, to the present application for display, LCD TV, LED backlight products continue to emerge, the market share continues to increase.
LED (Light Emitting Diode) LED was recognized as the terminator of fluorescent tubes, bulbs and other lighting equipment after its birth in the 1960s. LED lights, also known as light-emitting diodes, have the lowest power consumption of a single LED lamp compared to other light sources. From blue to red, LED lights come in many colors, and a special color is white. We customize it as "cold white" and "warm white".
The LED light source is composed of a plurality of grid-like semiconductors, each of which has an LED semiconductor, so that the LED backlight successfully realizes the planarization of the light source. The planarized light source not only has excellent brightness uniformity, but also does not require complicated optical path design, so that the thickness of the LCD can be made thinner, and at the same time, it has higher reliability and stability.
LED backlight advantages
Compared with CCFL backlight, the brightness of LED backlight is high, the brightness of long-term use will not decrease, and the body of LED backlight is thinner and the appearance is beautiful. The color is also softer, and the color of the hard-screen panel can make the eyes more comfortable. In addition, the LED backlight saves electricity and has low environmental radiation. At present, LCD TVs using LED backlights have become popular and the price is relatively affordable, which is the preferred product for purchase.
HIFU Piezoelectric Ceramic Parts
High Intensity Focused Ultrasound (HIFU) technology is to focus ultrasound on a single point to produce high energy, function on the dermis and SMAS layer of skin, stimulate the proliferation and recombination of collagen, effectively achieve the effect of compact contour and smoothing lines.
Focused ultrasound does not heat the skin surface, nor does it need to pass through the skin as a medium for the transmission of laser energy, so it does not affect the tissue on the skin surface and the tissue through which the laser passes, of course, there will be no excessive heat residue on the skin surface. In this way, the epidermis will not be affected by heat, which can reduce the Eastern people's thermal reaction easily, and greatly reduce the chance of scald. Focused ultrasoundtherapy produces thermal coagulation points in the SMAS layer, and the thermal effect diffuses outward from the coagulation points, so the heat source is concentrated in the SMAS layer to be treated. It can produce more collagen denaturation.
