From the perspective of the structure of LCD, whether it is laptop or desktop system, the LCD screen is a hierarchical structure composed of different parts. The LCD is composed of two glass plates, about 1 mm thick, between which is made of 5 glass plates containing liquid crystal material μ M evenly spaced. Because the liquid crystal material itself does not emit light, there are light tubes as light sources on both sides of the display screen. On the back of the liquid crystal display screen, there is a backlight plate (or even light plate) and a reflective film. The backlight plate is composed of fluorescent materials, which can emit light. Its main function is to provide a uniform background light source.

How does LCD work to improve brightness

LCD is composed of two glass plates.
the thickness of LCD is about 1 mm, in which there are 5 glass plates containing liquid crystal materials μ Because the liquid crystal material itself does not emit light.
there are light tubes as light sources on both sides of the display screen. On the back of the liquid crystal display screen, there is a backlight plate (or uniform plate) and a reflective film. The backlight plate is composed of fluorescent materials, which can emit light lines, Its main function is to provide a uniform background light source.

.
the light from the backlight enters the liquid crystal layer containing thousands of liquid crystal droplets after passing through the first layer of polarization filter layer.
the droplets in the liquid crystal layer are contained in a small cell structure.
one or more cells constitute a pixel on the screen.
it is transparent between the glass plate and the liquid crystal material The electrodes are divided into rows and columns. At the intersection of rows and columns, the rotation state of liquid crystal is changed by changing the voltage. The liquid crystal material acts like a small light valve.
around the liquid crystal material are the control circuit and the driving circuit.
when the electric field is generated by the electrodes in the LCD.
the liquid crystal molecules will be distorted, So the light passing through it is refracted regularly, and then filtered by the second filter layer to be displayed on the screen.
.
there are also weaknesses and technical bottlenecks in LCD technology.
compared with CRT display, the brightness, picture uniformity, image quality and so on There are obvious differences between the viewing angle and the reaction time.
both the reaction time and the viewing angle depend on the quality of the liquid crystal panel.
the uniformity of the picture has a great relationship with the auxiliary optical module.
there is a significant difference between the viewing angle and the reaction time
Roma LCD.
professional LCD manufacturer, located in Nanjing, the capital of Jiangsu Province, the ancient capital of the Six Dynasties<
for LCD,
the brightness is often related to its back light source.
the brighter the back light source is.
the brightness of the whole LCD will also be improved.
in the early LCD,
because only two cold light tubes are used, the brightness is often uneven, At the same time, the brightness is not satisfactory.
it was not until the introduction of four cold light source lamps.
it has been greatly improved.
.
LEB has a long service life.
LCD is an old-fashioned lamp, so it is mainly the service time when the product is eliminated.
there is no difference between the two.
