This is a STN negative LCD display. It is sky-blue background and
white characters(icons). STN LCD has wide viewing angle and very
beautiful.It is good for kinds of high end equipments. How to make
a LCD mold to get TN ,HTN,STN,FSTN,or VA LCD samples?Firstly,
please understand that there is no standard monochrome LCD display
panel in monochrome LCD industry (not including color TFT LCD,COB
moule and OLED) ,because specifications of LCD panel are quite
different, especially size, voltage,viewing direction,graphics and
so on.In order to custom make LCD easy,please confirm these
specifications below:LCD size (mm):Customers should tell us viewing
area size or total LCD size in millimeter(length,width). We will
help you design a final and economic LCD size.LCD total thickness
is 2.8mm or 2.0mm or 1.7mm. Usually,2.8mm is very common
thickness. LCD graphics(characters,icons)Customers should
send a simple LCD graphics(Formal CAD drawing or sketch) to us,then
we will understand how many segment it is.Our engineer will make
formal LCD drawing for your approval. LCD type: 1)
TN 2)HTN 3)STN 4)FSTN 5)VAHow
to choose LCD type? 1.Usually,TN LCD is used very widely,Such
as power meter LCD,telephone LCD,calculator LCD, electric cooker
LCD and so on. TN LCD is cheapest,but viewing angle is narrow.2.HTN
LCD is better than TN LCD. Display result of HTN positive LCD is
the same as TN positive LCD.But viewing angle is wider than TN.
Unit price of HTN LCD is close to TN LCD. 3. STN LCD is very
excellent LCD. It has a wide viewing angle. Usually STN LCD is used
in high-end equipments or display content too much!STN LCD not only
can make segment LCD,but also can make dot matrix LCD.Unit price of
STN LCD is higher than HTN LCD. 4.FSTN LCD is one of the best
LCD in monochrome LCD field. Display content even can be seen in
the sunshine. Display result of FSTN positive LCD is similar with
TN LCD,but viewing angle is much wider than TN LCD's. 5.VA
LCD is a new LCD type. It has high contrast and wide viewing angle.
In general,VA LCD has a excellent display result.If you want a
wonderful display result,VA LCD will be your best choice.Price of
VA is similar with FSTN LCD. LCD operating voltage:LCD
operating voltage is up to LCD drive chip.Usually,LCD operating
voltage range is 2.8~5.0V.We recommend to use 3.0V or 3.3V or 5V
operating voltage.5.LCD operating temperature and LCD storage
temperature:You can choose one from blow:LCD operating temperature
range:0 to 50ºC,then storage temperature range:-10 to 60ºC;LCD
operating temperature range:-10 to 60ºC,then storage temperature
range:-20 to 70ºC;LCD operating temperature range:-20 to 70ºC,then
storage temperature range:-30 to 80ºC;LCD operating temperature:-30
to 80ºC,then storage temperature range:-40 to 90ºC;LCD operating
temperature:-40 to 85ºC,then storage temperature range:-50 to
90ºC;Temperature range is wider,then price is higher.6.LCD Drive
Method:LCD drive method is up to LCD drive chip.For examples,Static
drive;1/2duty,1/2bias;1/3duty,1/2bias;1/4duty,1/3bias;1/8duty,1/4bias;1/16duty,1/5bias
and so on.7.Rear polarizer type:There are three types of polarizer:
transmission polarizer;transflective polarizer and reflective
polarizer.If No LED backlight,please choose reflective
polarizer.If LED backlight is necessary,then you can choose
transmission or transflective polarizer.Transflective polarizer is
better and expensive than transmission polarizer.But transflective
LCD will have a uniform light result compared with transmission
polarizer. What is more,when LED backlight is off, transflecitve
LCD will also have a good display result.For transmission
polarizer,when it is negative LCD or LED backlight alway be on,then
it is better use transmission polarizer.8.Viewing directionAs
viewing angle of monochrome LCD is not very wide,especially TN LCD
and HTN LCD, so it is necessary to confirm a best viewing
direction,so that we can get a best display result.As usual,LCD
viewing direction is separated into 6:00 direction and 12:
direction.6:00 viewing direction: When our line of sight is from
bottom to top of LCD,it is 6:00 viewing direction,such as telephone
screen,wall clock screen,air condition screen and so on.12:00
viewing direction: When our line of sight is from top to bottom of
LCD,it is 12:00 viewing direction,such as electric cooker display
screen.Viewing direction of LCD is very important,if we made a
wrong viewing direction,then the LCD display result was very bad.
Maybe customers have to re-make a LCD mold....9.Connection mode of
LCD.How to connect LCD on your PCB?There are four type of
connectors for your choice.Metal pin connector. It is very common
connection way. Pins should insert into PCB holes and solder it. It
is very strong and firm. LCD,LED backlight or PCB can be connected
together as a LCD module. 2.Zebra strip.When it is zebra
strip connector ,then zebra strip should be between LCD and PCB.You
should compact LCD and PCB evenly,so that zebra trip can co
