Educational Platform for LCD Displays

Optics in action: an overview of the advancements in information display education

“…The presented papers bring various improvements to the lab designs. These include remote packages [1], hands-on fabrication of actual displays [2,3], detailed laboratory testing of LCDs [4], and display addressing focused labs [5].…”

“…For the LCD labs, every paper proposed an educational approach [1][2][3][4][5]. [1][2][3] used an Arduino microcontroller to individually address the pins of the displays and the waveforms and refresh rates were generated on the software end.…”

“…This work gave students a look into how displays are fabricated. [4] took a technical circuit-level approach, using a custom printed circuit board (PCB) with three different LCDs and an oscilloscope to manually observe the waveforms on each segment of the display. In this work, a more rigorous microcontroller implementation was realized, with students needing to read and write to and from registers to generate the correct clock frequencies and output segments.…”

“…The main works that will be discussed are shown in [1][2][3][4][5]. While each paper presents a slightly different approach, the overall areas of focus are in: display fundamentals (color, addressing, refresh rates, etc.)…”

“…While each paper presents a slightly different approach, the overall areas of focus are in: display fundamentals (color, addressing, refresh rates, etc.) [1][2][3], hands-on teaching labs [2,3], remote teaching labs [1], liquid crystal displays (LCDs) [1][2][3][4], and light emitting diode (LED) technologies such as OLED and microLED [1][2][3]5].…”
