SBC8600B supports industrial display Mitsubishi AA104XF02 application
Mitsubishi AA104XF02 is an industrial display with operating temperature of -20~80°C, dot resolution 1024*768, LVDS single 6/8 bit drive interface, USB touch screen drive interface, product with reinforced protective glass. It is a The industry uses a very wide and stable display solution. The product driver uses the LVDS interface, Low Voltage DifferenTIal Signaling, which is a low voltage differential signaling technology interface. It is a digital video signal transmission method developed to overcome the shortcomings of high power consumption and large EMI electromagnetic interference when transmitting broadband high bit rate data in TTL level mode.
SBC8600B is an embedded single board machine based on TI Sitara Cortex-A8 AM3358 launched by Shenzhen Yinghao Special Technology Co., Ltd. It has strong application in image, graphic processing and industrial interfaces such as EtherCAT and PROFIBUS. It adopts core The separate structure of the board Mini8600B plus the bottom plate is designed. The motherboard has 6 serial ports (one of which has isolated RS485 interface), 1 with isolated CAN2.0 interface, 2 Gigabit Ethernet ports, 2 USB Hosts and 1 USB OTG, LCD screen interface, TF card, etc. Mainly used for industrial applications including portable navigation systems, digital video set-top boxes, portable educational/game devices, industrial automation, building automation, human-machine interfaces, teaching/medical equipment.
LVDS8000 Plus is an RGB to LVDS signal adapter board from Shenzhen Yinghao Special Technology Co., Ltd. The adapter board is based on the THine THC63LVDM83R signal converter, which converts RGB CMOS/TTL levels into LVDS signals at frequencies from 20MHz to 85MHz to display the image on the LVDS display. The module includes a 50-pin LCD input interface, an LVDS interface (2.0mm pitch, 20-pin DIP connector), a backlight power interface, a capacitive touch screen interface, and more.

Mitsubishi AA104XF02 backlight control voltage description
The backlight control voltage range of this screen is defined as 10.08V~13.2v. We can drive the backlight through the 12V voltage output voltage of J14 interface of LVDS8000 plus module. The screen backlight enable signal, the product definition needs to pass the voltage of 2.5v~5.5v. We can enable the signal through the 3.3V voltage output voltage of the J14 interface of the LVDS8000 plus module. The screen BLEN signal is connected to the LVDS8000 plus EN signal. The pin can illuminate the backlight of the screen.
The brightness of the backlight is controlled by the PWM signal, and the LVDS8000 plus J14 interface PWM signal is used to control the crime. The demo here is fixed at 3.3V. The brightness is not adjusted.
Mitsubishi AA104XF02 touch screen control CN3 interface
The touch control interface uses USB touch control. The USB touch driver has been integrated in the Linux kernel. The main signals are GND, D-, D+, VUSB. Therefore, you only need to connect this signal to the USB Host of SBC8600B.
The screen interface description is as shown in the figure, LVDS interface CN1, backlight control interface CN2, USB touch interface CN3.
The screen signal output interface of SBC8600B belongs to RGB type, so it needs to convert RGB signal into LVDS signal. Therefore, we have selected LVDS8000 Plus signal switching module from Infinity, which can directly convert RGB signal into LVDS signal output to the screen.
