waveshare 3.5 lcd touch screen made in china

3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.
Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.
However, for the first testing, you may want to use our image directly (if provided).Why the LCD still doesn"t work with the Waveshare provided image?Make sure the hardware connection is correct and connects fine.
Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They"re usually some poor copies of our early hardware revisions, and comes with none support service.

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.
3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)
1. Executing apt-get upgrade will cause the LCD to fail to work properly. In this case, you need to edit the config.txt file in the SD card and delete this sentence: dtoverlay=ads7846.
This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.

Touch screen monitors and touchscreen displays are everywhere. Just look around and you"ll notice a waveshare lcd or an LCD display within close proximity to you, (most likely, in the form of a smartphone).
An waveshare lcd, or liquid crystal display touch screen, is a display that can recognize a user"s touch through either resistive or capacitive sensing. This technology is probably one of the greatest technological innovations to hit the consumer market and is now an essential element of popular devices and brands across the globe. Thin film transistor (TFT) touch screens and displays have also improved consumer electronics and made this tech more accessible to everyday users.
A TFT touch screen combines the fundamental elements of a waveshare lcd with the advanced imagery TFT technology. These are the variants of waveshare lcd displays that most consumers see and use on a daily basis. While TFT displays use more energy than standard monochrome LCD displays, many models provide brighter and more detailed visuals than conventional screens.
As a popular technology that is now embedded in numerous devices, demand for touch screen LCD displays and related accessories like touch screen controllers is likely to grow. If you"re looking to sell to consumers, retailers, or other businesses, then Alibaba.com is a great choice to source wholesale monitors in bulk.
