What are OLED and QLED TVs, what are their differences, and which is Better? This page has information about their image quality, performance, durability, advantages, and disadvantages. In addition, there is information about the prices of Samsung OLED and QLED TVs on Amazon USA.

Most of the time, when someone decides to buy a new TV or is simply curious about the difference between OLED and QLED, which one is better, which one performs better, and which one is more durable, they get confused because they don't know much about QLED and OLED technologies. Are you in the same dilemma now?

As a TV technician, I can clear up all your confusion. QLED and OLED are two types of display technologies. A TV that uses a QLED display is called a QLED TV, and a TV that uses an OLED display is called an OLED TV.

What is an OLED TV?

OLED stands for Organic Light Emitting Diode. The images displayed on a TV screen are made up of many tiny light particles or pixels. In the case of an OLED display, those light particles are produced by organic light-emitting diodes, which is why it is called OLED TV. Because of this independent light source, this display does not require backlights, resulting in the following image quality and benefits:

• Each pixel in an OLED display is illuminated by individual red, blue, and green light, which creates deep blacks and high contrast ratios in the picture area, making the picture vibrant.

• We know that the more perfect the ratio of light and shadow in an image, the more eye-catching the image. OLED displays can create shadows with perfect blacks, significantly improving picture quality.

• OLED TVs have vast viewing angles, so the picture is equally bright from all angles: right, left, up, and down.

• Since OLED displays do not have an extra backlight section, the display is skinny, making the TV attractive.

What is a QLED TV?

QLED stands for Quantum Dot LED. It is a highly advanced version of standard LED display technology, not LCD. A TV that uses a QLED display is called a QLED TV. Quantum dots and backlight are the primary basis for creating different colors in QLED displays. A layer of quantum dots is placed on the surface of the backlight layer.

These quantum dots are tiny semiconductor particles emitting specific light of colors when the backlight light falls on them. RGB color filters are placed in front of the quantum dot layer to finally show the perfect red, blue, and green colors, so the color picture on the QLED TV appears vividly, and the picture quality is superior to that of the LED TV.

OLED vs QLED: Differences Between The Two TVs

OLED TV

The main attraction of OLED TV is its organic red, green, and blue LEDs that illuminate each pixel of the image with their light. The OLED particles give more light in the part of the image that needs more light and less light in the part that requires less light, and the OLEDs turn off where there is black color. As a result, perfect black and colored light appear perfectly in the picture, which increases the picture's contrast and makes the details more straightforward.

The difference in image quality between OLED and QLED TVs.

Advantages of OLED:

• Unparalleled contrast: Each subpixel of this display lights up and down individually at a breakneck speed when displaying moving images, creating an immediate clear difference between deep blacks and bright whites.

• Fast response time: Organic LEDs turn on and off quickly, making them ideal for fast-paced action scenes or gaming.

• Attractive design: OLED displays don't require a backlight, so TVs or monitors can be skinny.

Less motion blur: OLED TVs have less motion blur than QLED TVs, so you get a great experience when enjoying action scenes.

Getting Started with ATmega8 Microcontroller Programming using Arduino IDE. 

Since we will program an AVR microcontroller using Arduino, let's first understand what an AVR is. AVR is not an acronym for this microcontroller. It is a marketing term that stands for 'Advanced Virtual RISC'. The ATMEGA328P, ATMEGA88, and their equivalent microcontrollers use RISC (Reduced Instruction Set Computing) architecture, which works faster using fewer instructions.

Through this event, I presented all the easy and accurate processes of Arduino programming and simultaneously showed how to program ATMEGA8, ATMEGA48, ATMEGA88, ATMEGA168-20PU, and ATMEGA328P AVR microcontrollers. Learning to program so many models of AVR microcontrollers at once might be complicated, but no. The AVR microcontrollers mentioned have different capacities, but their circuits and wiring diagrams are the same, so let's get started.

To program an AVR Microcontroller using Arduino, you must first prepare the Arduino as an ISP programmer and upload the Arduino boot loader program to the ATmega8. The task is straightforward; follow the procedure given below to do so.

STEP-1

How to turn Arduino into an ISP programmer

First, connect your Arduino UNO or Nano to the computer using a USB cable. Then, launch the Arduino IDE Software  / Arduino program software.

1. Click on the File > Example > select Arduino ISP.
2. Click on the Tools > Board, then select your Arduino model from the board manager.
3. Click on Tools > Port, then select com port (Highlighted com port)
4. Click on Tools > Programmer > ISP > then select AVR ISP mkll.

Finally, upload the Skach by clicking the right arrow button below the menu bar. While uploading, the three indicator LEDs on the Arduino board will start blinking. After a few seconds, when one indicator lights up, and you will see the footer status bar indicating 'Done Uploading', you will know that the AVR ISP program has been successfully uploaded. Okay, now your Arduino is ready as an ISP programmer.

STEP-2

Content: OS-2S 94v-0 T-Con Board review and V320BJ8-Q01 Innolux LCD TV Panel Repair Tutorial.

This edition includes OS-2S 94v-0 T-Con board test points voltages, CKV point-out review, and T-Con board repair guidelines. This board is installed in an InnoLux LCD TV panel, model number V320BJ8-Q01. The gate driver circuits of LCD panels of most models manufactured by InnoLux are COG or chip-on-glass technology, so in many cases, they are not repairable.

However, the OS-2S 94v-0 T-Con board is installed on V320BJ8-Q01 panels, combining gate COF and source COF in one film. The COF has two sets of CKV connections on the right and left side, so these panels are easily repairable and will last longer in most cases. That's why InnoLux should make LCD panels using OS-2S 94v-0 T-Con board technology to avoid our complaints.

Dear friends, In response to many of your requests on YouTube and Facebook, I have published the voltage details of all the OS-2S 94v-0 T-Con board test points in the images below. I have observed that many of you search on Google by typing "OS-2S-94v-0 Datasheet PDF." Although I have not published this here in PDF format, hopefully, you will find almost all the information you need for this T-Con board repair.
