Block diagram of an HD44780U-based LCD module. The Hitachi HD44780 LCD controller is limited to monochrome text displays and is often used in copiers, fax machines, laser printers, industrial test equipment, and networking equipment, such as routers and storage devices.
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information.
An active-matrix liquid-crystal display (AMLCD) is a type of flat-panel display used in high-resolution TVs, computer monitors, notebook computers, tablet computers and smartphones with an LCD screen, due to low weight, very good image quality, wide color gamut and fast response time.
A Missouri couple has been charged with child abuse after police claim they performed a circumcision on a child at their home despite not having the medical training to do so.
In this formalism, a liquid crystal material is treated as a continuum; molecular details are entirely ignored. Rather, this theory considers perturbations to a presumed oriented sample. The distortions of the liquid crystal are commonly described by the Frank free energy density. One can identify three types of distortions that could occur in ...
Families scrambling for answers. Since September, the 50 men have appeared, one after the other, in front of the court in Avignon. Usually in rape cases character investigations can take several days.
The cost of the centerpiece of your Thanksgiving meal has declined for the second year in a row, with the cost of a 16-pound turkey reaching an average of $27, down about 6% from the year prior ...
The image shows a rotation of the director about 180° in a cholesteric phase. The corresponding distance is the half-pitch, p/2. A cholesteric liquid-crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral.
