Segment code LCD screens are widely used in many places in our lives due to their advantages of high contrast and low price. Do you know what should be paid attention to when selecting a segment code LCD screen? Let me give you a detailed introduction:

1. Look at the glass type of the segment code LCD screen

This is a mistake that many people usually make when they first come into contact with a segment code LCD screen. Different glass types will directly determine the size of the segment code LCD screen's visual range.

According to the positioning of the product, usually low-end products will choose the commonly used TN glass to make the segment code LCD screen. The best viewing angle of this glass is only about 30 degrees, so as long as the angle slightly deviates from the best viewing angle, you may not be able to see clearly up. For some industrial equipment, products that do not often look at the display screen, this kind of glass is very suitable.

For high-end products, we usually recommend customers to choose STN or other wide viewing angle glass, which not only ensures the high-contrast display effect of the segment code LCD screen, but also makes it easy to see pictures and text displayed in different positions.

2. Look at the display mode of the segment code LCD screen

The display methods of LCD screens are generally divided into positive film display and negative film display, and segment code LCD screens are often used outdoors due to their small size, so special attention should be paid to the display methods.

Relatively speaking, the negative display has a higher contrast ratio, and the display effect is clearer and brighter, but under the outdoor sunlight, the brightness of the display itself will be blocked by the sunlight, making it difficult to see clearly.

However, the positive display is more suitable for displaying in the sun. In the positive display mode, the bottom polarizer can be changed to a reflective type, and the brightness of the polarizer can be enhanced by sunlight to make it clearer in the sun.

3. Look at the display color of the segment code LCD screen

Generally speaking, segment code LCD screens are generally monochromatic, but with the development of the times, in order to meet the needs of the market, we usually add color effects to some negative display LCD screen structures or body, especially for current home appliances. There are many applications in the market, which not only look beautiful and high-end, but also reduce costs, and are stable and durable.

4. Look at the connection method of the segment code LCD screen

Common connection methods for segment code LCD screens generally include the connection of tube pins and conductive strips. Relatively speaking, the connection of the tube needle is more stable, and it is more suitable for the situation of displaying more content, but the cost is slightly higher. However, the connection price of the conductive strip is relatively low, but the stability is not enough. If it is bumped or knocked, it is easy to cause the display content to be misaligned. Therefore, the requirements for the peripheral structure are relatively high, so the corresponding connection method should be considered when designing the product to avoid unnecessary labor.
