The Displaytech EMB035TFTDEMO is a demonstration and development board for the Displaytech 3.5 inch color TFT display. The display is controlled by a Microchip PIC24FJ256DA210 microcontroller with integrated graphics controller. Furthermore, the demonstration board includes on-board external SRAM for extra frame-buffer memory as well as SPI flash for storing fonts and images. Capacitive touch screen is available for the 3.5" TFT display.
The Displaytech EMB043TFTDEMO is a demonstration and development board for the Displaytech DT043BTFT 4.3 inch color TFT display. The display is controlled by a Microchip PIC24FJ256DA210 microcontroller with integrated graphics controller. Furthermore, the demonstration board includes on-board external SRAM for extra frame-buffer memory as well as SPI flash for storing fonts and images.
I am blocked because I have the same TFT as on the photo. I have to connect it to a pcb that use the same SPI for the display and for the touchscreen. I am using a ESP32 but I am not sure it is meaningful.
When the TFT_RST pin is defined as output and set to HIGH, the XPT2046 returns only a value equal to zero when I read it. Otherwise, it replies with values that seems OK (they change when I touch the screen).
Note: I have a friend that has the same TFT. He did not remove the diode (was not aware off this) and his TFT works just fine using exactly the same firmware and the same board.
NHD-3.5-320240MF-PIC Eval Board | Evaluation Board with 3.5" Resistive TFT for PIC Starter Kit | Includes TFT NHD-3.5-320240MF-ATXL#-T-1 | Discontinued EOL Product
This NHD-3.5-320240MF-PIC Eval Board (DKSB1014B-ND) evaluation board was developed with Digi-Key to provide the user with a 3.5" resistive touch LCD and hardware interface for select Microchip PIC32 evaluation/starter kits. This PIC32 adapter board combines a combination of existing Microchip demonstration boards, our 3.5" resistive TFT without controller, and a custom interface board. This development tool features 3M bump-on"s for perfect mating to the Microchip evalution boards (SJ5749-0-ND), AVX flat flex ZIF connector (478-5598-1-ND), and Efficient Diodes Inc. white LED step-up backlight driver, (AP5724WG-7DICT-ND). Take the pain out of prototyping your next graphical display embedded application.
TFT (Thin Film Transistor) is a thin film field effect transistor, which can “actively” control the individual pixels on the screen, which can greatly improve the response time. General TFT response time is relatively fast, about 80 milliseconds, and the viewing angle is large, generally up to about 130 degrees, mainly used in high-end products. TFT belongs to the active matrix liquid crystal display, in the technology of the “active matrix” way to drive, the method is the use of thin film technology made of electrodes, the use of scanning methods “active pull “The light source is first transmitted upward through the lower polarizing plate when irradiated, and the light is conducted by the liquid crystal molecules to achieve the purpose of display through shading and light transmission.
TFT also improves the STN will flicker (water ripples) blurred phenomenon, effectively improving the ability to play dynamic picture. Compared with STN TFT has excellent color saturation, reproduction ability and higher contrast ratio, but the disadvantage is more power consumption, and the cost is higher.
TFT LCD is equipped with a semiconductor switch for each pixel, each pixel can be directly controlled by dot pulse, thus each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display, but also can precisely control the display color scale, so the color of TFT LCD is more true. TFT LCD is characterized by good brightness, high contrast, strong hierarchy and vivid colors, but TFT liquid crystal technology has accelerated the development of cell phone color screen. Many of the new generation of color screen cell phones support 65536 color display, some even support 160,000 color display, when the TFT high contrast, color-rich advantage is very important.
OLED display technology differs from traditional LCD displays by eliminating the need for a backlight and using a very thin coating of organic materials and a glass substrate that emits light when an electric current is passed through it.
And OLED display screen can be made lighter and thinner, the viewing angle is larger, and can significantly save electricity. However, although the future technology is better OLED will replace TFT and other LCD, but organic light-emitting display technology also has a short service life, screen size is difficult and other defects.
TFT liquid crystal for each pixel is equipped with a semiconductor switch, each pixel can be directly controlled by point pulse, so each node is relatively independent, and can be continuously controlled, not only to improve the response speed of the display, but also can accurately control the display color scale, so the TFT liquid crystal color more true.
TFT LCD screen is characterized by good brightness, high contrast, strong sense of hierarchy, bright colors, but also has the shortcomings of relatively power consumption and higher cost.
TFT is only a category of LCD liquid crystal display. oled is still not mature enough to replace LCD, but it has many advantages, the future will be very likely to replace LCD.
OLED, that is, organic light-emitting diodes (Organic Light-EmitTIng Diode), also known as organic electromechanical laser display (Organic Electroluminesence Display, OELD). Because with thin, light, power-saving characteristics, so from 2003, this display device in the MP3 player has been widely used, and for the same digital products DC and cell phones, previously only in some exhibitions showcased the use of OLED screen engineering samples, has not gone into the stage of practical application. But the OLED screen has many incomparable advantages of LCD, so it has been the industry is also favored.
OLED display technology is different from the traditional LCD display, no backlight, the use of very thin organic material coating and glass substrate, when there is an electric current through, these organic materials will be light. And OLED display screen can be made lighter and thinner, the viewing angle is larger, and can significantly save electricity.
