What are the parameters of these LCD TVs?

the S terminal is a kind of connector connected with the computer.
the circular terminal is similar to the keyboard port.
.
the color difference terminal is the best solution for connecting with the computer.
the S terminal output of the graphics card is converted to RGB three color, and then connected with the TV, The effect is much better than pure S terminal.

the English full name of HDMI is "high definition multimedia."
in Chinese, it means high definition multimedia interface.
HDMI interface can provide up to 5Gbps data transmission bandwidth.
it can transmit uncompressed audio signal and high-resolution video signal.
at the same time, it does not need to carry out D / A or a / D conversion before signal transmission.
the HDMI interface can provide up to 5Gbps data transmission bandwidth It can ensure the highest quality video signal transmission.
the advantage of applying HDMI is that only one HDMI cable is needed.
video signals can be transmitted at the same time, unlike the current need for multiple wires to connect; At the same time, due to the wireless D / A or a / D conversion, it can achieve higher audio and video transmission quality.
for consumers.
HDMI technology can not only provide clear picture quality, but also because the audio / video uses the same cable, It greatly simplifies the installation of home theater system.

LED is the abbreviation of light emitting diode.
.
.
LED applications can be divided into two categories: one is led single tube applications.
including backlight LED, infrared LED, etc; The other is the LED display,At present, there is still a certain gap between China and the world in the manufacturing of LED basic materials, but as far as LED display is concerned, China's design and production technology level is basically in line with the international level.
.
.
LED display is a display device composed of LED arrays.
it adopts low voltage scanning drive.
it has the following advantages: low power consumption, long service life, low cost, high brightness, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, high cost Compared with LCD, LED display has more advantages in brightness, power consumption, viewing angle and refresh rate.
the power consumption ratio of led to LCD is about 10:1.
and the higher refresh rate makes led have better performance in video, which can provide up to 160 bandwidth ° It can display all kinds of text, numbers, color images and animation information, and can also play TV, video, VCD, DVD and other color video signals. Multiple displays can also be broadcast on the Internet.
the single element reaction speed of organic LED display is 1000 times faster than that of LCD screen.
it can also be looked after in strong light, And it can adapt to the low temperature of minus 40 ℃.
LED technology can produce thinner, brighter and clearer display than LCD, which has a wide range of application prospects.

LCD is the full name of LCD: it includes TFT.
ufb, TFT, STN and other types of LCD.
.
.
TFT is commonly used in notebook LCD.
TFT screen is thin film transistor,It's an active matrix LCD with a special light tube on its back, which can actively control each independent pixel on the screen. This is also the origin of the so-called active matrix TFT, which can greatly improve the response time, about 80 ms, while STN's is 200 ms! Compared with STN, TFT has excellent color saturation, reduction ability and higher contrast, and it can still see clearly in the sun, but the disadvantage is that it consumes more power and costs more.
.
.
in short,
LCD and LED are two different display technologies, LCD is a display screen composed of liquid crystal, while LED is a display screen composed of light-emitting diodes.
compared with LCD, LED displays have more advantages in brightness, power consumption, viewing angle and refresh rate.
