innolux n070icg ips lcd panel factory

On http://www.aliexpress.com I purchased the following capacitive panel USB: (It is no longer present the seller on aliexpress, but we are always looking for more properties "Capacitive panel usb 7")

In addition to this problem, joined the fact that the panel touchscreen usb does not work well, I would say in an untouchable, the touch was crazy and it was not possible to use it.

So I thought, "It will be a problem of my monitor?" then I tried to change the firmware of the panel, the latest version is 1.7, so I started to download them and to make the upgrade .... but nothing.

Thinking it was a problem of my monitor, I opened the second monitor, always the Chalk Electronic, only that I had purchased the panel Capacitive USB and LCD screen separated, I start again to do many tests but had the same result as the previous warning ...

The LCD panel Innolux model N070ICG-LD4 is fantastic, it has the same specifications of the panel of Chalk Electronic, which are the same as the screens of the Nexus Tablet 7 inches.

If they managed to render and work well on the Chalk Electronic monitpr on Android, it would be the best solution, but for the moment millet panel, and I assure you that you"ll be in awe of the quality, is the model N070ICG-LD4 joined the panel bought on Aliexpress or panel Capacitive seller"s "Touch Display"

I have edited the file boot.ini, and the quality is slightly higher, but the difference with the Innolux IPS LCD is still far (The innolux is the best)

As can i see C1 is using 3.10 kernel. From 3.9 kernel default multitouch device class have a new quirks which is main cause of our issue. We need change Chalk"s touch panels device class from default to MT_CLS_NSMU.

I have a Chalk-elec 7" touch panel and screen on its way to me at the moment, when it arrives ill give it a test with the stock android image on my xu3 and post the results here.

Before purchasing this latest screen i purchased a screen&multi-touch kit off alliexpres this kit used the same LCD panel as the Chalk kit, but different touch panel. although the display worked perfectly out of the box there are no linux/android touch screen drivers for this kit.

Please make sure N070ICG-LD1 is the right LCD display panel you need before buying, mainly based on the model, brand, and the appearance to judge, some lcd display panels have the same model name, but with different appearance, example the position of the screw hole, so please carefully confirm if this is the right accessory you need. If you don"t find the right product on our website or need any help, feel free to contact us at any time.

8. PRECAUTIONS 8.1 HANDLING PRECAUTIONS (1) The module should be assembled into the system firmly by using every mounting hole. Be careful not to twist or bend the module. (2) While assembling or installing modules, it can only be in the clean area. The dust and oil may cause electrical short or damage the polarizer. (3) Use fingerstalls or soft gloves in order to keep display clean during the incoming inspection and assembly process. (4) Do not press or scratch the surface harder than a HB pencil lead on the panel because the polarizer is very soft and easily scratched. (5) If the surface of the polarizer is dirty, please clean it by some absorbent cotton or soft cloth. Do not use Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It might permanently damage the polarizer due to chemical reaction. (6) Wipe off water droplets or oil immediately. Staining and discoloration may occur if they left on panel for a long time. (7) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In case of contacting with hands, legs or clothes, it must be washed away thoroughly with soap. (8) Protect the module from static electricity, it may cause damage to the C-MOS Gate Array IC. (9) Do not disassemble the module. (10) Do not pull or fold the LED wire. (11) Pins of I/F connector should not be touched directly with bare hands.

8.2 STORAGE PRECAUTIONS (1) High temperature or humidity may reduce the performance of module. Please store LCD module within the specified storage conditions. (2) It is dangerous that moisture come into or contacted the LCD module, because the moisture may damage LCD module when it is operating. (3) It may reduce the display quality if the ambient temperature is lower than 10 ºC. For example, the response time will become slowly, and the starting voltage of LED will be higher than the room temperature.

8.3 OPERATION PRECAUTIONS (1) Do not pull the I/F connector in or out while the module is operating. (2) Always follow the correct power on/off sequence when LCD module is connecting and operating. This can prevent the CMOS LSI chips from damage during latch-up. (3) The startup voltage of Backlight is approximately 1000 Volts. It may cause electrical shock while assembling with converter. Do not disassemble the module or insert anything into the Backlight unit.
