Questions tagged [oled]

An OLED (organic light-emitting diode) contains a film of organic material that emits light when current is applied. They may be used to create digital displays that do not require a backlight giving a deeper black level and higher contrast than LCD displays.

How do devices like the Game Boy Advance achieve their frame rate?

I've been designing my own handheld gaming device based around an AVR microcontroller and a small OLED display. I started off with a monochrome display 128x64 pixels and can comfortably draw to it at over 60 frames per second. I recently reworked it…

Why are OLEDs used in screens insted of LEDs?

I was trying to google this question and couldn't find any information. And from reading some info on how they work i didn't find any significant difference asides from OLEDs being made out of organic elements. Also I would like to know if the…

Implementing a very high frame rate (~1Khz) OLED display

I'm interested in developing a very high frame rate OLED display capable of displaying ~1000fps with a resolution of around 1200x800 or so. This obviously has some pretty severe bandwidth requirements, and will likely require the use of an FPGA to…

How is an LED constructed, is it possible to build my own

I wondering if it would be theoretically possible for me to build my own led or oled. I am aware that this is not very practical, I'm more interested just as an exercise. I understand the basic theory behind leds and the materials necessary, but I'm…

extremely high frame rate oled

What's the maximum dotclk frequency for a typical OLED display with serial input? I've looked through some driver specs, example: SEPS525 but its not clear to me. I'm looking to update a small resolution RGB oled (64x64) display at several hundred…

SSD1306 Display SPI Connection or I2C (According to resistors)

I bought one of those cheap 0.96" OLED Displays from china, ebay. In the product description it states that it's a I2C Display, Ebay Link. I want to use it with an ATmega8. I connected it accordingly to the tutorials I found online: Pin1, GND: GND…

Why is the frequency response of an LED important?

I'm working on visible light communication where I fabricate my own organic LEDs. One of the ways to characterize them is "small signal analysis." I understand we are applying this analysis to see the bandwidth of the OLED, but I do not understand…

When an LED has a "light degredation" specification, does that means it's an OLED?

I was reading a datasheet for an LED panel, and I saw a spec for "Light Degradation" after 1000 hours. Can I assume this means it's an OLED (Organic LED), and that the organic materials will decay over time, reducing the brightness of the light? I…

OLED display using dspic33f i2c

I am trying to use OLED display in a dspic33f microchip. I've successfully initialized and sent data using I2C to OLED. I managed to display a small font(8pt) on the OLED. However, when I tried a bigger font, part of the font is being…

How large is "one pixel" for S5 AMOLED display?

Referring to Samsung Galaxy S5 OLED Pixel structure in oled-display.net, in particular this image illustrates the S5 AMOLED pixels: To my understanding, the yellow rectangle should represent "one pixel" as it is the smallest repeating…

How is this OLED cable being soldered to PCB?

In this video, from around 4:18 onwards, you see the cable of an OLED display being soldered. How is this soldering happening; i.e., how does the solder "flow" to the PCB pads given that the contacts on the cable present a physical barrier? Also,…

Refresh synchronisation with an SSD1322

Question: Is it possible to determine when the SSD1322 OLED driver module is "between redraws" of the screen? I'm thinking in a similar way to how game consoles/PCs are able to wait until the CRT scanline passes the last line on the screen and…
