Viewing Angle
How to select the viewing angle of segment lcd?
It is determined by the direction of friction in the orienting layer and cannot be changed by rotating the Polaroid. The perspective is named after the hour hand, such as 6 o 'clock perspective, 12 o 'clock perspective and so on.
The 6 o 'clock viewing Angle refers to the area from the plane direction at 6 o 'clock clockwise to the normal direction. The LCD display effect is ideal.
The 12:00 viewing Angle refers to the area from the plane at 12 o 'clock clockwise to the normal direction.
The viewing Angle of the LCD is determined by the position of the LCD display on the instrument. For example, the calculator is usually placed on the table or held in the hand, LCD made of 6:00 perspective is better. Some instruments have LCD screens below the eye level, usually at 12:00. The clock in the car is usually mounted on the right side of the driver to make a better 9:00 Angle.
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.
We have strict quality control, to ensure product quality.
Whole production line is in a low temperature, dry and sterile environment.
Whoever enters the workshop must wear overalls.
There is an air shower at each workshop doorway, to blow off dust particles on the surface of overall.
After products have been produced, every lcd or lcm will be 100% tested.
