Color depths is usually 24 bits (8 bits per color channel) or 18 bits per pixel (6 bits per color channel). These panels are widely available in eBay and notebook spare parts suppliers, so prices are pretty cheap. LVDS stands for Low-Voltage Differential Signals, and allows pretty long connection cable between LCD panel and controller due to differential signals. Below we will consider how to connect such panel to BeagleBoard\/PandaBoard and others OMAP-based development boards.<br><br>\r\nLVDS interface transmits video information encoded inside serial channels. LCD panel with LVDS interface requires 4 or 5 serial channels, usually, referred as RXCLK+\/- for clock signal, and RX0+\/-, RX1+\/-, RX2+\/-, RX3+\/- for data (pretty often you can find them denoted as D0+\/- or Y0+\/-, etc) . The most important thing is the bit assignments within the serial LVDS channels. Currently there are two common color depths in LVDS LCD panels, namely 18 bit and 24 bit. When connecting to 18 bit LCD there is a de-facto standard for the assignment of the color data bits on the LVDS serial data channels. For 24 bit LCDs there are two different formats: MSB and LSB (often referred as VESA and JEIDA by the names of associations) and it is important to know what your particular LCD panel expects. Some 24 bit LCD panels can be configured in either of the 2 formats which can be extremely useful, allowing you to design hardware that can drive either 18 bit or 24 bit LCDs with no hardware or software changes.<br><br>\r\nMSB (Most-Significant Bits are transferred in separate channel RX3) LCD panels expects the following data encoding inside serial channels:<br>\r\n<pre>\r\n<b>RX0+\/-:<\/b> G0,R5,R4,R3,R2,R1,R0<br>\r\n<b>RX1+\/-:<\/b> B1,B0,G5,G4,G3,G2,G1<br>\r\n<b>RX2+\/-:<\/b> DE,VS,HS,B5,B4,B3,B2<br>\r\n<b>RX3+\/-:<\/b> --,B7,B6,G7,G6,R7,R6<br><br>\r\n<\/pre>\r\nLSB (Least-Significant Bits are transferred in separate channel RX3) LCD panels expects the following data encoding inside serial channels:<br>\r\n<pre>\r\n<b>RX0+\/-:<\/b> G2,R7,R6,R5,R4,R3,R2<br>\r\n<b>RX1+\/-:<\/b> B3,B2,G7,G6,G5,G4,G3<br>\r\n<b>RX2+\/-:<\/b> DE,VS,HS,B7,B6,B5,B4<br>\r\n<b>RX3+\/-:<\/b> --,B1,B0,G1,G0,R1,R0<br><br>\r\n<\/pre>\r\nAs you can see, 18-bits LSB panel can be connected to system with 24-bits LSB format, just by omitting data in RX3 channel. But you will see mess of colors on LCD if try to connect 18-bits panel to 24-bits MSB system.<br><br>\r\nOur v1 PCB was designed for 24-bits MSB panels. These panels are used mostly by very expensive industrial LCD panels. Current version of PCB (v2) we designed for 24-bits LSB and 18-bits panels, as they are used by most of cheap notebook panels.\r\n<\/div><\/div>\n<div class=\"pane\"><a href=\"http:\/\/www.chalk-elec.com\/?p=1345\"><\/p>\n<h6>Problems with PIC firmware on first batch of PCB v2<\/h6>\n<p><\/a><br \/>\n  <a href=\"http:\/\/www.chalk-elec.com\/?p=1515\"><\/p>\n<h6>Problem with artifacts on Pandaboard ES<\/h6>\n<p><\/a><\/div>\n<div class=\"pane\">\n<h5 class=\"toggle\"><a href=\"#\">LVDS board v1 (24-bits MSB panels)<\/a><\/h5><div class=\"toggle-content\"><div class=\"block\">\r\n  <a href=\"http:\/\/goo.gl\/bslH9\"><h6>Schematic<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/SVJ0I\"><h6>Gerbers<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/y4tC8\"><h6>BOM<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/O1KBY\"><h6>Assembly<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/6FKBb\"><h6>LVDS pinout<\/h6><\/a>\r\n<\/div><\/div><div class=\"toggle-space\"><\/div><h5 class=\"toggle\"><a href=\"#\">LVDS board v2 (Pandaboard\/Beagleboard)<\/a><\/h5><div class=\"toggle-content\"><div class=\"block\">\r\n  <a href=\"http:\/\/goo.gl\/Vzlpq\"><h6>Schematic<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/Jrinj\"><h6>Gerbers<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/lDCIx\"><h6>BOM<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/7TtgD\"><h6>LVDS pinout<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/7wXAb\"><h6>PIC firmware (ver.1) - simple backlight control with ambient sensor<\/h6><\/a>\r\n<\/div><\/div><div class=\"toggle-space\"><\/div><h5 class=\"toggle\"><a href=\"#\">LVDS board v2 (BeagleBone)<\/a><\/h5><div class=\"toggle-content\"><div class=\"block\">\r\n  <a href=\"http:\/\/goo.gl\/qUVUb\"><h6>Schematic<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/7TtgD\"><h6>LVDS pinout<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/25aHCI\"><h6>Gerbers<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/7wXAb\"><h6>PIC firmware (ver.1) - simple backlight control with ambient sensor<\/h6><\/a>\r\n<\/div><\/div><div class=\"toggle-space\"><\/div><h5 class=\"toggle\"><a href=\"#\">HDMI-LVDS converter (RaspberryPi)<\/a><\/h5><div class=\"toggle-content\"><div class=\"block\">\r\n  <a href=\"http:\/\/goo.gl\/3SKAC\"><h6>Schematic<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/Om6MmK\"><h6>LVDS pinout<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/f0QDqP\"><h6>Gerbers<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/iAdzC9\"><h6>BOM<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/7wXAb\"><h6>PIC firmware (ver.1) - simple backlight control with ambient sensor<\/h6><\/a>\r\n<\/div><\/div><div class=\"toggle-space\"><\/div><h5 class=\"toggle\"><a href=\"#\">LCD datasheets, EDID and drawings<\/a><\/h5><div class=\"toggle-content\"><div class=\"block\">\r\n  <a href=\"http:\/\/goo.gl\/dGmUY\"><h6>10\" B101AW02_V3 (1024x600 px)<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/OjpcL\"><h6>10\" LP101WX1 (1280x800 px)<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/Lv14c\"><h6>10\" LP101WX1 (DWG)<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/f48GE\"><h6>7\" CLAA070NA (1024x600 px)<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/DcwR0Z\"><h6>14\" AUO panel dimensions<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/KWEFyI\"><h6>15.6\" AUO panel dimensions<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/dIJlR1\"><h6>14\" AUO panel EDID data<\/h6><\/a>\r\n  <a href=\"http:\/\/goo.gl\/OcwM7W\"><h6>10\" LG panel EDID data<\/h6><\/a>\r\n<\/div><\/div><div class=\"toggle-space\"><\/div><\/div>\n<div class=\"pane\">\n<h5 class=\"toggle\"><a href=\"#\">Do you ship worldwide?<\/a><\/h5><div class=\"toggle-content\"><div class=\"block\">\r\n\tYes, we ship worldwide!<\/div><\/div><div class=\"toggle-space\"><\/div><h5 class=\"toggle\"><a href=\"#\">How long does a shipment usually take?<\/a><\/h5><div class=\"toggle-content\"><div class=\"block\">\r\n\tWe ship from Malaysia.

For standard mail we can't provide insurance, so it is on your own risk that parcel is delivered safely. Of course, we pack your parcel carefully to minimize risk of damage, but sometimes (rarely) shit happens. <\/div><\/div><div class=\"toggle-space\"><\/div><h5 class=\"toggle\"><a href=\"#\">How much does shipping cost?<\/a><\/h5><div class=\"toggle-content\"><div class=\"block\">\r\n\tThe shipping costs vary depending on the quantity that you are ordering, the shipping destination, and the shipping method that you select. You can find estimated shipping cost after you place product to shopping bag, and before you pay your order.<\/div><\/div><div class=\"toggle-space\"><\/div><h5 class=\"toggle\"><a href=\"#\">Who pays custom duties and import taxes?<\/a><\/h5><div class=\"toggle-content\"><div class=\"block\">\r\n\tAll duties and taxes for international shipments are the responsibility of the customer. Chalkboard Electronics is not responsible for any extra charges once the original package has been shipped. If the customer refuses to pay these extra charges, the return shipping and any additional fees will be taken out of the cost of the order, with any remaining funds being refunded to the customer.
