lcd屏显示蓝底白字原理

An LCD screen displaying blue background and white characters

works based on the principle of liquid crystal technology.

LCD屏幕显示蓝色背景和白色字体是基于液晶技术的原理工作的。

Liquid crystal displays utilize the properties of liquid crystals - a

unique state of matter that exhibits both liquid and solid

characteristics. When an electric current is applied to the liquid

crystal material, it changes the orientation of the molecules, causing

them to either allow light to pass through or block it, resulting in the

display of images or characters.

液晶显示器利用液晶的特性 - 一种同时表现液体和固体特征的独特物质状态。

当电流施加到液晶材料上时，它会改变分子的方向，使它们能够通过或阻挡

光线，从而显示图像或字符。

The blue background on an LCD screen is achieved by using blue

color filters in combination with backlighting. When the liquid

crystals block the white light from the backlight, only the blue light

gets transmitted through the color filters, creating the impression of

a blue background.

LCD屏幕上的蓝色背景是通过在背光和蓝色滤光片组合使用来实现的。当液

晶屏蔽了来自背光的白光时，只有蓝光通过颜色滤光片传递，从而产生了蓝

色背景的印象。

As for the white characters, the electric current controlled liquid

crystals allow the white light from the backlight to pass through

when they align in a specific pattern, resulting in the display of white

characters against the blue background.

至于白色字符，受控的电流使液晶分子以特定的模式排列，允许白光通过背

光，从而在蓝色背景上显示出白色字符。

This color combination of blue background and white characters is

common in LCD screens as it provides high contrast and readability,

making it suitable for various applications such as digital watches,

calculators, and many other electronic devices.

LCD屏幕上蓝色背景和白色字符的颜色组合在各种应用中很常见，因为它提

供了高对比度和可读性，使其适用于各种应用，如数字手表、计算器和许多

其他电子设备。

In conclusion, the display of blue background and white characters

on an LCD screen is achieved through the control of electric currents

to manipulate the orientation of liquid crystals, in combination with

color filters and backlighting to produce the desired colors and

contrast for optimal readability and visual appeal.

总之，在LCD屏幕上显示蓝色背景和白色字符是通过控制电流来操纵液晶

的方向，再通过彩色滤光片和背光来产生所需的颜色和对比度，以实现最佳

的可读性和视觉吸引力。
