Some people believe you need a projected capacitive touch screen for latex gloves. However, resistive touchscreens work under pressure, so gloves, stylus, or anything that pushes the touch screen will work.
Under "Touchscreen Display Modules" choose the product you are using. Under the "Downloads" tab, select Portrait Firmware to download the .UPG file. Use the BMPload program to change the firmware. Note: SLCD5/SLCD5+ products display landscape orientation only and cannot do portrait orientation.
The 5.7″ QVGA (320×240) is an older standard than the 4.3″ display, and that’s why the 5.7″ has a lower resolution. The lower the resolution, the higher the brightness, so the 5.7″ does have one redeeming feature. We favor “standard” sizes and resolutions as much as possible for long-life availability. There are no standard bodies for small TFT displays, only form factors and resolutions adopted by multiple vendors. You have several options for higher resolution, and these are all powered by our SLCD5 controller. These options are very similar in resolution (dots per inch (dpi) or pixel pitch). Reference 4.3″ dot pitch 0.198mm = 128dpi Options: 5.7″ VGA (640×480) dot pitch 0.180mm = 141dpi (tighter than the 4.3″) 6.4″ VGA (640×480) dot pitch 0.204mm = 124dpi 7″ WVGA (800×480) dot pitch 0.190mm = 134dpi All of the above are available from multiple panel vendors.
You can ruggedize our resistive touch somewhat by putting a ZAGG film on it.
Reach Technology does not support any OLED (organic light emitting diode) displays.
If you want the lowest cost, you buy the displays yourself. However, we cannot provide technical support for displays that we don’t sell. Suppose you’re not already aware of the vagaries of the LCD business and especially of the availability of LCD products. In that case, you might want to read how the LCD business is very different from others.
The firmware in our SLCD5/SLCD5+ display modules does not support SDHC cards (those over 2 GB capacity). This is because the low-level SD card protocol changed, so even if you partition the SDHC card and create a FAT16 file system, the underlying protocol is incompatible. You will need to use a standard SD card with a capacity of 2 GB or less.

Reach Technology began in 1988 and is still supporting products designed in the mid-1990s. As long as there are customers for a particular board and parts are available, we will continue to make it. Our job is to keep the product current and deal with part obsolescence issues. The user interface will stay the same. Read more about our commitment to long-term supply.
One option is to define a macro the application can use when needed. A macro can turn the display off with the “v off” command. First, define a particular hotspot over the entire screen, then assign this hotspot to another macro. When the user touches any location on the touch screen, the assigned macro is run. The ‘wake-up’ macro could remove the hotspot and turn the display back on with the “v on” command. A screen touch can notify the application with either a standard “x” notification from the SLCD or a custom message from the ‘wake-up’ macro. See the example macros in the file PowerSaveExampleMacros.txt.
