LS013B7DH01 Application Field and Working Principle

LS013B7DH01 display module belongs to type of display modules, including LCD, OLED and graphic display modules. It is a passive, bistable reflective LCD type display module that can be used in different application fields, such as smart energy, industrial and medical applications. The display module can support up to 1 W brightness when applied with a voltage of 3 V, and it is driven by a single 1.2 V supply. As it is a reflective type, it consumes very low power in comparison with other types of display modules. In this article, we will discuss the application field and working principle of LS013B7DH01.

Application Field:

LS013B7DH01 has a range of application fields, mainly in smart energy, industrial and medical applications. It is widely used in applications that require long-term, bistable and low power consumption displays, such as in IoT endpoints, energy meters, industrial controls, and medical devices. In addition, it can also be used in other application fields that require low power consumption, such as embedded products and wearable devices. Applications in these fields can benefit from the high brightness and large operating temperature range of the display module.

Working Principle:

LS013B7DH01 is a reflective type display module, which means that it does not require any backlighting source to be seen. Instead, it uses ambient light to reflect off the pixel structure of the display and generate an image. The display module consists of two main components – an active matrix array and a light PSA (patterned retardation layer). The active matrix array is made up of thin-film transistors (TFT), which act as switches that can turn each pixel on or off to create an image. The other component, the light PSA, is a patterned retardation layer that is placed directly over the TFTs. This layer consists of a pattern of different thicknesses of LC (liquid crystal) that has a refractive index that can be tuned to reflect various colors. This layer is responsible for enhancing the display’s brightness and color accuracy.

When a voltage is applied to the display module, the TFTs act as switches that control the pixels, turning them on or off. The voltage applied to the pixels determines their brightness. When the pixels are turned on, the LC layer of the light PSA will reflect the ambient light and generate an image. This image can be further enhanced with contrast and color. Thus, this is how LS013B7DH01 works to create an image.

Conclusion:

LS013B7DH01 is a reflective type display module with a range of application fields, mainly in smart energy, industrial and medical applications. This display module uses an active matrix array made up of thin-film transistors and a light PSA to generate an image. When a voltage is applied to TFTs, the pixels are turned on and the LC layer of the light PSA will reflect the ambient light to create the image. As this display module consumes very low power and has a wide operating temperature range, it is an ideal choice for applications that require bistable and low power consumption displays.
