advice on 240 x64 displays

[longpole001]

hi hendric ,

i love to give details , but i am just searching the net on posable lcd modules at the moment , raised the good point on if the display need to show the 100/sec digit until it stops , else it blur anyway .
this part of the design stage for the controller part of the project

i have been looking at few options , my requirements are

1. display in direct sunlight - reflective is best option but some do offer good use in direct without backlight even if backlight is there
2. large digits - 25mm high prefered or close for display of the timer with 6- 8 digits needed with dots
3. 6ock view angle
4. device run on batteries - so try and use less power is best
5. need to display other alphanumeric data as well and looking at adding a specific display 16x 2 or 20 x4 line for this requirement

options when taking these item into consideration come up with
a. Using a glass lcd for time count , and alphanumeric for other requirments
b. large 40 x2 alphanumeric with a special large font for digits timer , still need addtional alphanumric for other function display
c. a graphic display for digits and if large enough combine 2 display requirements - custom fonts required constant updating timing for other items maybe an issue

Problems.
1, Glass display require a driver to be made and PCB and are often only availalbe in large production runs in quanity of 500 or more , else u may not get them , but some searching will turn up few here , buy in 100 lots only
2. combined cost of glass LCD display and driver , pcb will exceed the cost of 5.5 " graphic display 240 x64 which can display a large digits.
3. Alphanumeric display are great and you can make some large custom fonts to use 2 or 4 lines , but the fonts look avg and gaps in the chars are seen , you wont Ever find any that have the same size or even close as glass lcd for the cost , but they do
have drivers on board
4. the larger the display the more power it uses
5. cost , cost cost , i need to make this with all requirement for about $100usd , and good design v cost is driving me nuts

sorry vented

Cheers

Sheldon

Hi,
Have you seen the SmartGLCD from MikroE? Currently out of stock but seems to fit the bill @99USD.
I've got one and I started writing PBP code for it a year or so ago, didn't have any particular use for it so the project kind of stalled after a while.
