Graphic lcd modules

 interface connection in two ways: one is the direct access mode, the other is indirect access. Either way, you want to access the module must first read the Serial display modules  contents of the status register to determine the "busy" flag can be accessed when COG LCD Display  Graphic lcd modules not busy. Direct access method is a module interface as a memory or  devices directly linked to the MCU bus,to access memory or I / O device mode the module operation. Indirect access MCU module is operated via software simulation control timing.
Write instructions on the display module and write data write operation into the left screen and write the right screen. The difference Graphic lcd modules between writing about half the screen is only set corresponding chip select signals, and the difference between writing instruction and writing data when the write data is set RS Graphic lcd modules register select signal. Initialization operation is completed and opened to determine the display position of the display.

Interface design and software TFT LCD Display  programming described above has been successfully applied to the data acquisition system operating parameters of the display system to good effect; coupled with significant anti-button control, parameter setting, flip, the establishment of a good man-machine interface.

Serial display modules

Character LCD Module is type thin film transistor liquid crystal display, which is "truecolor" (TFT). TFT LCD for each pixel has a semiconductor switch, each pixel can through the point of pulse directly control, which are relatively independent, each node and can be continuous control, not only improves the display speed, and can precisely control levels, TFT LCD color so more true. TFT LCD display screen is the feature of good brightness, high contrast, administrative levels feels strong, bright color, but there are also more power consumption and high cost.

TFT (Thin Film Transistor) Thin Film field effect Transistor, namely belongs to one of the active matrix liquid crystal display. It can be "active" to control of individual pixels on the screen, this can greatly improve the reaction time. General TFT relatively fast response time, about 80 milliseconds, and large visual Angle, generally can reach 130 degrees.
TFT LCD polarity reversal mode:
The driving voltage of liquid crystal molecules cannot be fixed at a certain values, otherwise, time is long, the Serial display modules polarization phenomenon will happen, so as to gradually lose their optical properties. Therefore, in order to avoid damage to the characteristics of the liquid crystal molecules of the liquid crystal molecules, the driving voltage polarity transformation must be conducted, it is need to display the voltage to the liquid crystal display is divided into two kinds of polarity, one is normal polarity, the other is a negative polarity.

Character LCD Display

Graphic lcd display module is 1.4 inch blue background with 128x64 monochrome white pixels cog(chip on glass) lcd module,ST7565R controller,compact size,high contrast,wide operating temperature,white led backlight,stn-blue lcd,fpc connection,optional zif connector and led backlight connector.It supports 6800 8-bit,8080 8-bit parallel and 4-wire serial spi interface.
OLED displays easily controlled by MCU such as 8051,PIC,AVR,ARDUINO,ARM and Raspberry Pi.Serial display modules can be used in any embedded systems,industrial device,security,medical and hand-held equipment.

Graphic lcd modules even achieve prevention and early diagnosis of the disease

Its base is golden silk, attached to the skin by electrostatic after this electronic skin through real-time monitoring pulse, heart rate , body temperature, vibration, and other muscle groups physiological indicators of human health , human health data changes and make timely feedback , even achieve prevention and early diagnosis of the disease.
Because the electronic skin is extremely sensitive with conductive nanomaterials , even if it is a bit of quivering muscles electrical changes , it can be accurately sensed.
This is a University of Texas research team at Seoul National University in Korea jointly developed electronic skin . It is only 4 cm long, 2 cm wide, 0.003 cm thick , stick in your hand graphic lcd display module looks a bit like a tattoo.
And electronic skin developed by Chinese scientists , as it built a variety of human data monitoring sensor with high sensitivity , but it also equipped with a memory that can store and transmit the work to complete the monitoring data .
More cattle is that this electronic skin also designed a pharmaceutical interface for real-time data and Serial display modules according to human health, the drug is released directly into the human body through the electronic skin more quickly and efficiently complete the course of treatment .
However , whether domestic or foreign electronic skin , they also need the help of an external power supply and data transmission devices to work properly, form and function from the wearable device market there is a certain distance.
