The segment code liquid crystal display for beauty instruments is a kind of liquid crystal display device commonly used in beauty instruments. Here is a detailed introduction:

Principle: It utilizes the change in the arrangement of liquid crystal molecules under the action of an electric field. The liquid crystal material twists the propagation of light under the action of the electric field, thus realizing image display.

Definition: The segment code liquid crystal display, also known as pattern LCD, pen segment LCD, or monochrome LCD, is a type of LCD product. It controls the on - off state of each segment by applying a voltage between the "segment electrode" (SEG) and the "common electrode" (COM) of the liquid crystal, so as to display different characters, numbers, and graphics.

• Low - cost: The manufacturing process is relatively simple, with low production costs, which helps reduce the overall cost of beauty instruments.
• Low - power consumption: It has low power consumption, which is beneficial for beauty instruments powered by batteries, enabling longer - lasting use.
• Simple and Intuitive Display: It can simply and clearly display information such as working status, parameter settings, and battery levels of beauty instruments, which is convenient for users to operate and view.

• TN (Twisted Nematic) Liquid Crystal Screen: It has a fast response speed and low manufacturing cost, but a relatively narrow viewing angle, usually around 50 degrees. It is commonly used in simple electronic devices such as calculators and remote controls, and is also applicable to some beauty instruments with lower requirements for the viewing angle.
• HTN (High Twisted Nematic) Liquid Crystal Screen: Its viewing angle is slightly wider, the contrast is improved, and the power consumption is low. It is often used in some simple instruments and meters, and is also one of the choices for beauty instrument segment code liquid crystal displays.
• STN (Super Twisted Nematic) Liquid Crystal Screen: The ability to display complex graphics and text is enhanced, but the response time is longer. It was previously widely used in electronic dictionaries, early mobile phones, etc., and can also be applied to beauty instruments that need to display more complex information.
• FSTN (Film Compensated Super Twisted Nematic) Liquid Crystal Screen: It has a high contrast ratio and a wide viewing angle, and is often used in multifunctional electric meters, power detection instruments, and some high - end beauty instruments that have certain requirements for display effects.

• Hair - styling Beauty Instruments: Such as 烫发夹,直发器,etc. The segment code liquid crystal display can display temperature, time and other parameters to help users accurately control the styling process.
• Skin - care Beauty Instruments: Such as facial - lifting devices, acne - removing devices, etc. It can display working modes, intensity levels, and remaining battery power, allowing users to adjust the usage according to their own needs.
