From home appliance control panels and electronic watches to digital reading screens for industrial equipment, segmented LCD has become an ideal choice for embedded systems and simple display requirements due to its low power consumption, low cost, and simple driving. This technology is maintaining its place in today's high-precision display field through continuous innovation. 01 What is segmented LCD? Segmented LCD, also known as segmented LCD screen or patterned LCD screen, is a general term for non dot matrix LCD products that use pen segment display technology. Its name originated from the early application of LCD screens, mainly used to replace LED digital tubes. The most basic 7-segment digital display can show numbers 0-9, similar to the display on calculators and electronic clocks. Unlike common dot matrix displays nowadays, segmented LCD displays have fixed content and are composed of pre designed pen segments (such as numbers, letters, or simple symbols). These pen segments are very flexible in arrangement and shape, not only can they be made into the common "8" shape, but they can also be made into any shape, including company logos, various patterns, and text. 02 Technical Principles and Driving Mechanisms The driving core of segmented LCD is based on "scanning" or "time-division multiplexing" technology, utilizing the "visual persistence effect" of the human eye to achieve stable display. The segment code LCD is composed of a matrix structure consisting of multiple intersecting "common terminals" and "segment terminals". Liquid crystal material is sandwiched between two transparent electrodes, and its transparency is changed by applying voltage - when there is no electric field, the arrangement of liquid crystal molecules allows light to pass through, displaying the background color; When an electric field is applied, the liquid crystal molecules deflect, blocking light and displaying dark colors. Liquid crystals have a key characteristic: they must be driven by AC voltage, and DC voltage can cause electrolysis and permanent damage to the liquid crystal material. Driving an LCD requires generating precise square wave signals to ensure the correct phase relationship between the display and non display segments. 03 Driving Mode and Implementation Method The driving of segmented LCD is divided into two types: static driving and dynamic driving. Static driving is suitable for COM terminals with few or simple displays. Each segment is independently connected to a driving pin, which is easy to control and flicker free. However, it occupies a large number of pins and is only suitable for a small number of segments. Dynamic driving is suitable for multi segment displays, such as calculators and electronic watches. It groups segment electrodes and scans different COM terminals in a time-sharing manner, utilizing the persistence effect of human visual perception to achieve stable display. For example, the 4COM driver divides the screen into 4 groups and alternately activates each group of COM. The advantage of this method is that it can reduce the number of pins, but the disadvantage is that it requires strict timing control. The dedicated driver chip greatly simplifies control complexity by incorporating multiplexing logic and LCD voltage generation. These chips can communicate with microcontrollers through SPI/I2C, greatly saving MCU pin resources. 04 Technical advantages and limitations The most significant advantage of segmented LCD is its extremely low power consumption, making it suitable for battery powered devices. The driver chip such as HT1621 can drive up to 128 pen segments, equivalent to 16 "8" characters, while the interface is only a few serial pins. Compared with other display technologies, segmented LCD is still clear and visible under strong light, with low cost and simple driving. However, the limitation of segmented LCD is that its display content is fixed and cannot dynamically update any graphics. This makes it unsuitable for scenes that require displaying complex graphics or changing rich information.

Normally, VA lcd is larger viewing angle than TN, HTN lcd, High contrast is its characteristic . To consider the product environment, product display effect when you choose LCD screen. The most basic feature is high brightness, the high luminance value, the more bright of contents. The high contrast, the more colorful saturation, and more stronger stereoscopic. Conversely, the contrast is low and the colors are barren, and the image becomes flat. Compared to VA and TN type lcd screen, the contrast value is quite different. Meanwhile, lcd screen viewing range is also an important parameter: TN viewing range is small, the angle of view will gradually show unclear (it refers to the screen in front of the clear range can be seen ) . While the VA lcd is wide viewing range, no matter what angle of view to see the display screen, you can see very clearly;

Here are some aspects to consider: Display Technology Principles TFT - LCD (Thin - Film Transistor Liquid - Crystal Display) It uses a liquid - crystal layer to control the passage of light. The TFT technology is employed to improve the image quality by precisely controlling each pixel. It requires a backlight source to illuminate the liquid - crystal layer, and the light passes through the liquid - crystal layer, which can be twisted and rotated to control the amount of light passing through each pixel, thus forming an image. LED (Light - Emitting Diode) LEDs are semiconductor devices that emit light when an electric current passes through them. In the context of displays, LED can refer to two things: LED - backlit LCD, where LEDs are used as the backlight source for an LCD display, and OLED (Organic Light - Emitting Diode), where organic materials are used to emit light directly without the need for a backlight. OLED is a type of LED display technology. Image Quality TFT - LCD Advantages: It can achieve high resolution and good color accuracy. With the development of technology, the color gamut and contrast ratio of TFT - LCDs have been continuously improved. They can display a wide range of colors and are suitable for various applications such as computer monitors, televisions, and mobile phone displays. Disadvantages: The contrast ratio may be limited compared to some LED - based displays, especially in displaying deep black colors. The response time of the liquid - crystal layer may also cause some blurring in fast - moving images. LED (OLED in particular) Advantages: OLED displays offer excellent contrast ratios because each pixel can be individually turned on and off, resulting in true black levels and high - quality image display. They also have a faster response time, which is beneficial for displaying fast - moving images such as in gaming or action - packed videos. The color accuracy and viewing angles of OLED displays are often very good. Disadvantages: OLED displays may be prone to burn - in, where static images left on the screen for a long time can cause permanent damage to the pixels. They are also more expensive to produce compared to TFT - LCDs, which can lead to higher - priced products. Power Consumption TFT - LCD The power consumption of TFT - LCDs mainly comes from the backlight. Although energy - saving technologies have been developed, such as using more efficient LED backlights, the overall power consumption is still relatively high when displaying bright images or when the backlight is set to a high level. LED (OLED) OLED displays consume less power when displaying dark images because the pixels can be turned off completely. However, when displaying bright images, the power consumption may be higher than that of some TFT - LCDs. In general, for applications where there are a lot of dark - screen displays, such as in some mobile phone usage scenarios, OLED can be more energy - efficient. Applications TFT - LCD It is widely used in various fields, including computer monitors, televisions, mobile phones, tablets, and industrial displays. Its relatively low cost and mature technology make it a popular choice for mass - market applications. LED (OLED) OLED is commonly used in high - end mobile phone displays, some high - end televisions, and in applications where high - quality image display and thin - profile designs are required. For example, OLED is often preferred in curved and flexible displays due to its better flexibility and thinner form factor. In conclusion, the choice between TFT - LCD and LED (especially OLED) depends on specific requirements and usage scenarios. If cost - effectiveness, high resolution, and general - purpose display are the main considerations, TFT - LCD may be a good choice. For those who prioritize high - quality image display, excellent contrast ratios, and fast response times, and are willing to pay a higher price, LED - based displays, especially OLED, may be more suitable.
