Technical parameters:

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, digital clocks, calculators, and mobile telephones, including smartphones. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks. LCD screens have replaced heavy, bulky cathode-ray tube (CRT) displays in nearly all applications. LCD screens are available in a wider range of screen sizes than CRT and plasma displays, with LCD screens available in sizes ranging from tiny digital watches to very large television receivers. LCDs are slowly being replaced by OLEDs, which can be easily made into different shapes, and have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given display size and a slimmer profile (because OLEDs use a single glass or plastic panel whereas LCDs use two glass panels; the thickness of the panels increases with size but the increase is more noticeable on LCDs) and potentially lower power consumption (as the display is only "on" where needed and there is no backlight). OLEDs, however, are more expensive for a given display size due to the very expensive electroluminescent materials or phosphors that they use. Also due to the use of phosphors, OLEDs suffer from screen burn-in and there is currently no way to recycle OLED displays, whereas LCD panels can be recycled, although the technology required to recycle LCDs is not yet widespread. Attempts to maintain the competitiveness of LCDs are quantum dot displays, marketed as SUHD, QLED or Triluminos, which are displays with blue LED backlighting and a Quantum-dot enhancement film (QDEF) that converts part of the blue light into red and green, offering similar performance to an OLED display at a lower price, but the quantum dot layer that gives these displays their characteristics can not yet be recycled.

Application: 
Lcd Display to be use on Air Conditioner and Remote Controller, Smart Thermostat, Humidity etc.

Duty cycle
This parameter is also known as Duty number or COM number. Because STN/TN LCD is usually driven by time-division dynamic scanning mode, in this mode, the ratio of the effective turn-on time of each COM to the whole scan cycle, i.e. Duty, is fixed, equal to 1/COM number. Bias: Bias
The driving waveform of SEG/COM of LCD is analog signal, and the ratio of analog voltage to the maximum output voltage of LCD is called bias. Generally speaking, Bias is expressed by the ratio of the lowest output voltage to the highest output voltage. Generally speaking, there is a certain relationship between Bias and Duty. The more the number of Duty, the shorter the scanning time of each COM. To achieve the same display brightness and contrast, the voltage of VON will be increased, and the difference between the selection level and the non-selection level needs to be increased, that is, Bias needs to be increased. There is an empirical formula between Duty and Bias, that is, to achieve the same display brightness and contrast.
