LIQ UID
CRY STA L  
DISPLAY (LCD)
The term liquid crystal describes a substance 
that lies  in a state between liquid and solid 
but exhibits the  properties of both. Since 
their first observation in the  19th century, 
LCD technology has been enjoying  various 
advancements, and currently, it accounts for  
an enormous share in the entire display 
market area.
The power consumption of LCD is directly  
proportional to the drive frequency (as the 
frame rate  lowers, the power consumption 
reduces) and the  displayed image.
ELECTRO N IC PA PER 
 (E-PAPER)
Electronic paper is a vigorous display 
technology that  can rip off traditional paper. 
Just as in the case of  LCD, e-paper also 
belongs to the non-emissive  display category, 
and here we do not need any  backlight. It is 
because the ambient light from nature  is 
enough.
Significant characteristics of e-paper include  
flexibility, reliability, multi-functionality, and 
ultra-low  power consumption. They even 
lead to zero  consumption in the non-
updating period. You can  find several 
technologies in small sizes, although  there 
are approaches with A5 size.
ORGANIC LIGHT-EMITTING 
 DISPLAY (OLED)
OLED or organic light-emitting diode is a 
light-  emitting technology that is made 
when you place  several thin organic films 
made from carbon and  hydrogen between 
two conductors. They will emit a  bright light 
when the electric current is applied.
It makes them thinner and more efficient. As 
they are  manufactured on a small scale, they 
are available at a  high price. Several studies 
conclude that while using  this technology, 
the consumption of displays rises  strongly as 
per the size.
ELECTROLUMINESCENT 
 DISPLAY (ELD)
Electroluminescent display technology is well-
known  for taking advantage of the light-
emission  phenomenon because of the strong 
electric field. You  can find a solid-state thin 
phosphor film and insulator  stack deposited 
on a glass substrate in the ELD driven  by high 
voltage electronics generating a positive and  
negative pulse. Plus, they are known for being 
a cost-  efficient light source method leading 
to low power  consumption.
Electroluminescent technology is well-
known for  having lower consumption and 
contrast ratios. It is  best to pay attention to 
the viewing angle values of  180 degrees.
