Various Types of LCD Display for Raspberry Pi to Look At
When you purchase Raspberry Pi, it is very important that you have found a nice LCD display that you can use with it. If you search around in market, you will find that there are some varieties of LCD display for Raspberry Pi available in market. Most of these display modules have worked on multi tasking concepts and therefore enable Raspberry Pi for multiple tasking performances.
There are some varieties in LCD displays that you can mount on your Raspberry Pi and unleash the power of core computing. Let’s have a quick look,
TFT Display module
These are one of the commonly used LCD display module with Raspberry Pi. These modules comes in various models, therefore buyer must make good inquiry to get the type of TFT module they are looking for with their Raspberry Pi. 3.5 inch TFT LCD display model is popular in this category. This display unit comes with navigation keys and Printed Circuit Board (PCB). But, that is not mandatory with each model; in some you will find only navigational keys only and in some navigational keys along with PCB.
HDMI Monitor display module
This monitor category is blessed with bigger size and resolution of 800×480. This module is integrated in a manner that it automatically converts its resolution modes into VGA or AV modes, wherever required. This display mode carries push buttons, which can be used to assign and operate various computing functions. These push buttons are not required to be connected, as it configures itself once GOIP and SPI pins are connected with Raspberry Pi.
Another model in this category is 17 inch One Thin Line Monitor (OTLM). This LCD display for Raspberry Pi has 1280 x 1080 Radxa Resolution, which produces high quality graphics.
Monochrome TFT display
This LCD display module bears a resolution of 48 x 84 pixels. It is available with Graphic SPI LCD monitors and Printed Circuit Board. This display module has a very easy user interface. It has got its built in controller and memory. Out of the all display units that can be used with Raspberry Pi, this module has got the least price in the market at present.
Finger Print Sensor Module
This module has dual interface – UART (TTL) and USB. This module of Raspberry Pi has got RF reader integration, which enable Radio Frequency transmission system. This LCD display for Raspberry Pi has got a very simple integration process with various Biometrics applications, and therefore is used mainly for Finger Prints. It can store up to 8 digit long User IDs. This tiny machine can store up to 3000 finger prints with each finger print size being 496 byte. It uses a very peculiar match mode for biometrics applications. According to its user manual, it accepts identifications in a ratio of 1: N, but operates verification in ratio of 1:1.
These are some useful LCD display module, which are popular nowadays in the global market. However, many other companies are working on building newer versions of display module for Raspberry Pi; time will only show the results.
