Poszukuje tabeli z fabryczna rozdzielczoscia matryc monitorow, wyswietlaczy LCD w DPI (pikseli/punktow na cal)
Taka wielkosc mozna latwo obliczyc znajac wymiaru panelu - szerokosc i
rozdzielczosc w poziomie.
I dzielac rozdzielczosc w poziomie przez szerokosc wyrazona w calach.
A jak sie nie zna rozdzielczosci w pikselach, to liczba dzielac
szerokosc przez rozmiar plamki i zaokraglaja do wartosci calkowitej.

To znalazlem

LCD native DPI : 72-96, 91, 110, 120,

rozmawialem z grafikiem i mowil, ze jego monitor ma rozdzielczosc w
poziomie 72 DPI (19 lub 20" LCD)

A co z wyswietlaczami do komorek, malych telewizorow LCD, przenosnych
odtwarzaczy DVD itp.
Gdzie mozna znalezc pelna tabelke porownawcza wszystkich matryc LCD,
dostepnych na rynku, stoowanych w sprzecie elektronicznym, video,
photo, dvd, komputerowym .

Oczywiscie interesuje mni rozdzielczosc fabryczna, czyli punktow
matrycy, a nie interpolowana programowo.

Taka mam tabelke

All LCD monitors are fixed resolution devices. LCD monitors use a
matrix
of cells so the pixels are in a fixed location and therefore define the
native resolution of the monitor. What you are seeing is the spcers
between the cells of the LCD. For example a typical 18" LCD monitor
with
a dot pitch of 0.2805mm and a horizontal viewable area of 359mm has a
native resolution of 1280 in the horizontal direction. Math is simple,
359 divided by 0.2805 equals 1279.85 or 1280 if you account for the
small rounding error. Same calculation can be made in the vertical
direction. DPI can be caluclated as follows. Your 21" monitor most
likly
has a horizontals viewable area of 395mm or 15.6 inches. Divide the
horizontal resolution by the viewable area = DPI. If you are running
1280 resolution 1280 / 15.6 = 82 DPI. An 18" LCD at 1280 x 1024 with
aviewable area of 359mm or 14" same calcualtion, 1280 / 14 = 91 DPI.

In this example the LCD has better DPI however it looks grainer due to
the lower Dot pitch and the spacers used in LCD monitors.

i dalej

I've got an 18in flat panel monitor with screen res set
at 1280 x 1024. This is the screen's "native
resolution". Some displays & fonts are small for my eyes
so I might increase DPI from 96 to 120.

Viewsonic 200 DPI

This 22.2-inch LCD panel being sold by Viewsonic uses the same panel
developed and marketed by IBM last year. The difference is that IBM
charged nearly $20,000 for its version; Viewsonic plans on selling this
one for around $8,000. That's still pretty pricey -- what makes this
panel so special?

Try 9.2 million pixels, for one thing. This 16x9 aspect panel has a
native resolution of 3840x2400 pixels. That translates to roughly 200
dots per inch.

wchodzisz na jakas strone producenta matryc np LG-Philips
http://www.lgphilips-lcd.com/homeCon...cmn000_j_e.jsp

i masz tam podzielone matryce LCD: monitory, TV, laptopy, inne (komorki GPSY
itd)
przy kazdej masz podane dokladne wymiary i rozdzielczosc mozesz sobie
obliczyc DPI
