The VMOB-8.4S is an optically-bonded 8.4 outdoor lcd display, which is a daylight viewable monitor. We design it for use as an outdoor screen in indirect sunlight. It is recommended for indoors where high ambient light decreased the view-ability of standard LCD monitors. The VMOB-8.4S features a 4:3 aspect ratio. Additionally, this 8.4″ outdoor lcd display features an extremely wide operating temperature range. It has rear VESA mount holes, and our 3 year warranty.

Some monitors have a sheet of glass over the LCD panel. This protects the panel from accidental or intentional damage. However, the glass also produces unwanted glare and reflections. Internal reflections in the air gap between the glass and the LCD panel diminish image quality even further. In order to combat this, monitors are optically bonded.

Optical bonding is the process of laminating protective glass or a touch screen panel to the LCD panel. An optical-grade resin is inserted between the glass and LCD. This completely fills the air gap. It will not only eliminate the internal reflections, but increase the contrast ratio. This makes the screen much more viewable in bright light conditions. Optical bonding will also eliminate internal moisture and condensation. Moreover, it will make the monitor more rugged and durable. Lastly, an Anti-Reflective coating is applied to the outside of the glass. Consequently, this will drastically reduce glare and surface reflections.

We design these daylight viewable monitors to operate in nearly any environmental conditions.  Whether in frigid conditions or blazing heat, these daylight monitors will survive and thrive. To clarify, some of these monitors will operate in temperatures down to -22°F (-30°C).  They will also withstand brutal heat.  Moreover, operating  temperatures go up to +140°F (+60°C).  Additionally, the rugged steel enclosure will assure years of reliable imaging performance.  Specifically, typicalMTBFfor these monitors is 50,000 hours.

How many volts can the SLCD43 reset line take? We want to hold the reset line at 5 volts high, and set it low to reset, but weren’t sure if the board could handle it.2022-04-08T11:01:41-07:00

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.

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.

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).

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.

All SLCD controllers have a reset circuit triggered when the voltage supplied to the board drops below a particular threshold. Sometimes called brown-out protection, this trigger ensures the controller’s processor does not incorrectly execute and possibly change its internal programming when it loses power. This reset happens when the input voltage to the controller sags (dips down below 10% of nominal).

I did a screen capture of an image and displayed it on the SLCD6 or SLCD43 (in high color mode) and see color banding that was not in the original. What do I do to get rid of this?2022-04-08T10:49:07-07:00

The SLCD controller family has an “auto-switch” feature to change the active serial port. You need to connect to an alternate serial port, perform the auto switch, and disable the power-on macro.

If you use older versions than SCLD5 BMPload Version 2.1.4 or SLCDx BMPload Version 1.8.2, you may experience Vista OS-related problems (error messages, corrupt device downloads, etc.). Download a newer version at BMPload.

We don’t have a GUI builder tool for SLCD products. Still, we recommend using standard bit-mapped image development and manipulation tools to create images and then our Screen Layout Utilities for graphic placement. The standard tools include programs such as Adobe Illustrator and Photoshop or the free program called GIMP (GNU Image Manipulation Program).

Once you have your bitmap images defined, you can use our free Screen Layout Utilities (a plug-in for GIMP) to design your screen layout and generate a macro that will display on your LCD. We have tutorials for using GIMP to create bitmaps and using the Screen Layout Utilities within GIMP, and both tutorials are online in our video library.

Our SLCD display modules do not support any wireless interface directly. “Bridge” chips are available that operate as Serial RS-232 to (Bluetooth, WiFi, IR, etc.) adapters. If you are willing to design your own adapter board, our display modules may meet your needs, and it’s a matter of your intended application and the size/cost/performance constraints you are facing. Alternatively, our newer G2 modules do support WiFi interfaces.

I am looking for a complete 4.3-inch touch Panel PC that runs WinCE 5.0. I need RS-485 and wireless. Your LCD looks great but it needs a PC controller. Do you have any recommendations?2022-04-08T10:38:14-07:00

SLCD43 does not support WinCE 5.0 running on this display controller. Our SLCD43 does support RS-485 via an external RS-232 to RS-485 converter. This type of adapter automatically enables the RS-485 transmitter when the RS-232 transmit data is active. It supports either half-duplex or full-duplex RS-485. Our SLCD43 can be controlled by a PC or a microprocessor using a physical serial connection to support CMOS/TTL logic levels. We also can load macros so applications can reside on the device with minimal external control (via commands). Find your unit under the “Touchscreen Display Modules” and then look in the “Documents” tab to download our software and hardware manuals for further information.

When I opened the .ZIP file I found an .ELF file, but expected the firmware to be in a .BIN format. Do I need special loader for SLCD5 products?2019-10-24T14:40:28-07:00

The SLCD5  (7″, 8.4″, and 10.4″) firmware loads bitmaps and macros from serial data on Flash into RAM before it displays anything on the screen. This way, the screen does not come up blank. However, this loading can take time, especially if there are a lot of bitmaps. There are two ways to speed things up:

If the splash screen is set to bitmap 1 (e.g., command “*SPL 1”), this bitmap is loaded and displayed first before all the others are loaded. This setting can reduce the on-time delay.

A special inverter cable, P/N 23-0121-12, can be used with ERG 8MAD series inverters. This cable enables the inverter as soon as power is turned on, so the screen goes white right away. Then once the controller is initialized and there are bitmaps loaded, the screen will display normally. The downside of this solution is that the inverter always runs at full brightness.

Start BMPload. You will see a box called “Screen Snapshot” with a button called “GetScreen.” Make sure your Port Settings are correct, then click GetScreen. Browse to the desired file location, name the file, then click Save.

Use a terminal emulator, insert an SD card into the display module, then send the command “*getScreenAsBMPFile”. This step will copy the current screen to a file on the SD card.

Use BMPLoad.exe to load the .bin file from your PC and then connect to your SLCD. Click the “Store into SLCD” button. Now your bitmaps and macros are in the SLCD. You can use a terminal program to coax the SLCD into telling you what’s there.

Issue the command “lsmac” and the SLCD will list out all of its macros, and you will have captured them into a file, which you can then edit and use as your new macros.txt file.

Issue the command “lsbmp” and the SLCD will list out details for all your bitmaps, and you will have captured them into another file (bitmap_info.txt), which you’ll want for future reference (most importantly, for the dimensions of each bitmap).

What you’ll need to do from here on out is display a bitmap on the SLCD display and then use the “GetScreen” feature of BMPLoad to capture a bitmap of the display. The resulting bitmap file can then be edited to cut out the background and keep just the desired bitmap data (referring to the bitmap_info.txt file for the index of each bitmap and its corresponding Width and Height. For example:

Click on GetScreen and specify a file to save the screen to (Warning: It will be about 150K and will take a couple of minutes); in this case, I’d suggest naming the file “disp_bm_1.bmp”.

Now that you’ve captured your macros and bitmaps, archive them. Create a new folder and copy the archived files into it, and then you can make changes. You can use BMPload to put your new macros and bitmaps into your SLCD and move ahead when you’re done. Contact that consultant, though, and get the original macros and bitmaps, just in case.

The SLCD controller family uses UTF-8 encoding for non-ASCII characters. To incorporate UTF-8 characters into a macro file, you need to use an editor that supports UTF-8 encoding. Windows Notepad can do this. First, make sure you have a Unicode font installed (Arial Unicode MS comes with Microsoft Office) on your desktop to see the Unicode characters. Then start Notepad and set Format->Font to a Unicode font. Then select File->Save (or Save As…), and at the bottom of the pop-up box, you will see Encoding: ANSII. Click on the drop-down box and select UTF-8. Then save to set the encoding. Then, copy the following into the editor:

The font or encoding is wrong if you don’t see the Russian text. Then, save the file as “testMacro”.txt or similar, download this macro file and a Unicode font (get font files) to the SLCD, select the font and run the macro. You should see the Russian for “Press here” (or “Click”) on the screen. See Fonts for Embedded Touch Screen Development for a comprehensive explanation of working with fonts.

Does your controller board support a SCREEN WIPE option (a command or API that temporarily disables the touch sensitivity and allows the user to clean the screen)?2022-04-08T10:27:47-07:00

There are several ways to do this – all touch can be disabled, but it would be easier for the host to blank the screen, make the entire screen a hotspot (touch-sensitive region) and display a countdown number that gets reset when the unit is touched. When cleaning is finished, the screen will no longer be touched, and the host can resume regular operation.

I’m trying to establish communication with the board SLCD5 connector J7 pin 4 and pin 10 ( RX TX CMOS ). When I connect pins 5 and 6 (RS-232) the communication is normal. What should I do?2020-09-29T11:35:20-07:00

Connector J7 pin 10 may need a pull-up resistor to your host 3.3V supply and avoid a problem of the SLCD5’s 3.3V supply and your host 3.3V supply being different.

The “SET TEXT ALIGNMENT” command can control how the “TEXT DISPLAY” command places text on the screen. The following commands draw a rectangle, set the text alignment to centered horizontally and vertically, and draw a string centered in the box:

There are no provisions for storing application files on the SD card, except for saving screenshots and using the screenshot command for customer product documentation. The SD card is used for system updates since this is much faster than using the RS-232 port. Otherwise, our modules are intended to be human interface devices only.

See the “xset” command in the Software Manual (find the manual for your module from the Touchscreen Display Modules menu, in the Documents tab) for information on adding touch characteristics to a button or hotspot.

When drawing a full-screen bitmap (.BMP) and using hotspots within it for control, the hotspots invoke macros. The macros redraw the screen. The colors being wrong is a side effect of how typical hotspots work. A standard hotspot defined by the “x” command specifies a touch-active area. When the area is touched, the screen is reverse imaged (foreground becomes background and vice versa) to provide visual feedback of the touch. When the button invokes a macro that redraws the screen, the screen is drawn while the button is pushed and the foreground/background colors are reversed. Then when the button is released, the hotspot is reversed even though the underlying image has changed. The solution is to use the “xs” command that does not change the screen when the defined hotspot is touched. The new screen will provide visual feedback, or the macro can do its reverse imaging.

Button text is limited to 19 characters for button numbers less than 118 and 49 characters for button numbers 118 and up (SLCD+ is always limited to 19 characters).

The SLCD board has an 80KB frame buffer which povides for 8-bit per-pixel color at 320 x 240 resolution. A constant color palette is used to support a consistent color image with multiple on-screen bitmaps. The palette maps the 8-bit pixel index to the 12-bit color value sent to the panel.

Chetco Digital uses 5.7″ QVGA touch screen control panels to create the display below. See several other screenshots. Chetco Digital makes an analog to digital instrumentation hub, enabling a touch screen gauge interface, remote switching, engine data logging, and SeaSmart.NET NMEA 2000 compatible wireless networking for marine, automotive, and industrial applications.

Sciton uses an 8.4″ display module in JOULE, which offers an unprecedented array of laser and light wavelengths through its three distinct delivery modes: arm, fiber, and broadband light. As a result, JOULE allows practitioners the maximum versatility to provide the broadest range of aesthetic and surgical procedures available from a single platform.

Bitmaps are RLE compressed for storage. To see the effect of compression on a particular image, download the BMPload program and run it. Ignore the initial error (no SLCD attached) and add a bitmap. Then click on the bitmap name, and the information on the right-hand side will show the compressed size.

To display a changing number, use a monospace font and always write the same number of characters. So, if it is a 4-digit number, and the value is 1, send ”  1″ (three spaces and a 1) and if it is 123, send one space and the three numbers. The monospace font ensures that each number takes the same horizontal space, so they don’t shift left and right as they change. Finally, you may want to add a “wvr” command (find the manual for your display module in the Documents tab for your specific product) to ensure that the number changes while the display is not being refreshed on that part of the screen. Note that wvr does not work in portrait mode due to the way the LCD is built. See also our video tutorial called “Simple Output Formatting to Manage Fixed-Width Fields.”

Reduce host computer data transmitting frequency:Reduce the rate of the data sent from the host computer to the SLCDx display controller to reduce the flicker that occurs when writing data.

Avoid refreshing the entire screen: If you have a large bitmap, try to avoid re-displaying the bitmap since re-writing the bitmap can be relatively slow.

Bitmaps can be compressed in our SLCD based products to save Flash memory space. The disadvantage is that compressed bitmaps display more slowly. To balance performance and Flash display storage, it is best to use the “Enable Bitmap Compression” checkbox in the BMPload application. For bitmaps that are large (for example cover the entire screen), or are re-drawn often, compression can be disabled by using inserting the string “.unc” into the file name, e.g. “01_MyBitmap.unc.bmp”. This tells the BMPload program not to compress this file’s image. Background bitmaps for slider objects and meter objects and sliding graphics (“xio” command) need to be uncompressed as well.

The SLCDx controllers can run either 8-bit color or high-color firmware (the original SLCD is 8-bit only, for high-color, use the SLCD+). In 8-bit color firmware, when a 24-bit “exact” palletized image is displayed, the bitmap routine maps the 24-bit color to the closest available in the fixed SLCD palette. In high-color firmware, the BMPload program converts 24-bit color bitmaps to 16-bit color (RGB565 format) before storing them on the controller board.

I want to place a bitmap over screen content, like a transparent GIF. That is, I’d like a non-rectangular bitmap. How can I do this?2022-04-08T10:06:59-07:00

See the manual section “Working With Bitmaps” for more detail. You can download the manual by locating your module in the Touchscreen Display Module menu and then the Documents tab.

Is there a way to stop the splash screen from automatically executing, as the system appears to run the macro and then the splash screen?2022-04-08T09:56:52-07:00

Similarly, check the “Set Splash Screen” and set Bitmap Number to 0, which will disable the splash screen. The splash screen and power-on macro are typically not set together.

Currently, SLCD products only support BMP file formats. However, many image applications (Microsoft Paint, Adobe Photoshop, etc.) allow conversion from non-BMP to BMP file formats. Watch tutorial videos for more details.

Thanks to one of our customers, there is a way to edit your SLCD macro files and have syntax highlighting. The TextPad shareware editor can do the custom highlighting. Download this ReachMacros.syn file and follow these instructions.  You should now see macro highlighting in TextPad. Please note that Reach Technology is not responsible for supporting this file.

We have not done a full EMC/EMI report since modules are not finished products. Likewise, self CE certification has to be done on a finished product, and our modules are sub-assemblies. We have had many customers pass CE and FCC testing with varying enclosures. We do have an EMC “prescan” of the SLCD43 (currently shipping model, 40 pin 400 nit) with an FCC Class A limit line taken while the display was showing a “checkerboard” pattern, which is the worst case for display EMI. We use a spread spectrum oscillator for the display, which helps spread emissions. See the report.

To provide added ESD protection to the SLCD43 display modules, we use 3M 1170 conductive tape to connect the metal frame of the LCD panel to the digital ground (equals ESD or chassis ground) on the SLCD43 controller board. The controller board has grounded mounting holes that need a solid connection to chassis/Earth/ ESD ground. This approach provides approximately 4KV ESD protection. However, from a regulatory point of view, ESD testing has to be done with the display module in the customer’s enclosure with a system ground. If you are trying for high ESD immunity, the bezel “should” be metal or metalized plastic, although it may be OK with just plain plastic. Our suggestions are:

Use a flexible conductive gasket to ground the metal frame of the LCD panel to the front panel metal. Sold as EMI shields, they also work well for ESD. See example.

Maple Systems touch screens are highly feature-rich regarding speed and connectivity; hence, they’re more complicated to use (and more costly). If you don’t need 3D animations, the ability to play video or music, or Ethernet connectivity, you will find our SLCD solution more than adequate and much simpler to use. If you need some of those features, check out our G2 display modules. Since our SLCD interface to your system is a Command Line Interface implemented over a serial port, any UART microcontroller with enough speed and memory to handle your application will do just fine. If you want to discuss your application requirements and which of our products will best meet your needs, please contact our technical support team.

Use Photoshop or the open-source equivalent GIMP to design a user interface screen on a PC. It can be hard to match the embedded fonts on the SLCD family of controllers with Windows fonts. If you need an exact match, you must do two things:

If you need fonts not shown, please get in touch with the technical support team and specify the Windows font name, the size in points, and the character set (either ISO 8859-1 or a Unicode subset). See the Fonts for Embedded Touch Screen Development for a comprehensive explanation of working with fonts.

We support UTF-8 encoding. Find UTF-8 for a given Unicode. For Unicode, the subset size determines the size of the .SIF font. The complete Unicode set of a font like SimSun at 16 pixels high (not 16-point) is 946KB and has over 20,000 characters. See Fonts for Embedded Touch Screen Development for a comprehensive explanation of working with fonts.

Compressing bitmaps in our SLCD products allows you to save Flash memory space. The disadvantage is that compressed bitmaps display more slowly. To balance performance and Flash display storage, it is best to use the “Enable Bitmap Compression” checkbox in the BMPload application. For bitmaps that are large (i.e., cover the entire screen), or are re-drawn often, disable compression by inserting the string “.unc” into the file name (e.g. “01_MyBitmap.unc.bmp”). This string tells the BMPload program not to compress this image. Background bitmaps for slider objects and meter objects and sliding graphics (“xio” command) need to be uncompressed. Using the strategy above should keep your application visually responsive while conserving Flash memory for future additional bitmaps.

Detection time depends on user-adjustable touch parameters. Factory settings recognize touches in around 20ms. The corresponding serial response sends immediately if no commands are being executed. However, there is no guarantee since the screen could be performing some command when the unit is touched. The evaluation kit unit has a very responsive keyboard demo. However, the ultimate response time depends on how the unit is used.

SLCD controller boards use PicoBlade connectors. They are made by Molex and are miniature (1.25mm pitch) which makes them hard to make by hand. International Component Technology can make these cables for you to use to connect to your microcontroller board.
