“(Samsung Display) will terminate its supply of LCD panels in June,” an industry source said Monday. The company has been manufacturing its lower-end panels in Asan, South Chungcheong Province.

The long-awaited move came as LCD TV panel prices have been on a constant decline. This led to greater losses for Samsung Display, while Chinese competitors have been ramping up their dominance in the global industry supported by state subsidies and tax breaks.

LCD TVs are considered lower-end when compared to those using cutting-edge TV components such as organic light-emitting diode panels and quantum dot display panels.

According to market intelligence firm Omdia‘s estimate compiled by Daishin Securities, 43-inch LCD panel prices fell 46 percent from September 2021 to May this year, while that of 55-inch panels and 65-inch panels both declined 34 percent over the cited period.

This marks the end of Samsung’s three-decade LCD TV panel business. Once the largest LCD TV panel supplier in the world, Samsung Display‘s market share has gradually shrunk from 22 percent in 2014 to around 2 percent this year.

Samsung Display had sought to exit the business from before 2021, but has been hanging on in part due to Samsung Electronics’ LCD panel supply shortage.

Choi Kwon-young, executive vice president of Samsung Display, confirmed the company’s full exit from the LCD TV panel business within this year in a first-quarter conference call in April.

Given that Samsung’s LCD TV panel exit has long been anticipated and carried out gradually, Samsung Electronics will “unlikely be affected by Samsung Display‘s LCD panel exit” in terms of its continuity in the LCD TV set business, noted Kim Hyun-soo, an analyst at Hana Financial Investment on Monday.

Samsung looks to pivot to quantum dot display technologies for its TV panel business, using quantum dot light-emitting diodes or quantum dot organic light-emitting diodes.

As for the anticipated collaboration between TV maker Samsung Electronics and the world‘s sole white-OLED TV panel supplier LG Display, Kim of Hana said the launch of Samsung’s OLED TV is unlikely within this year due to prolonged negotiations.

Back in 2016, to determine if the TV panel lottery makes a significant difference, we bought three different sizes of the Samsung J6300 with panels from different manufacturers: a 50" (version DH02), a 55" (version TH01), and a 60" (version MS01). We then tested them with the same series of tests we use in all of our reviews to see if the differences were notable.

Our Samsung 50" J6300 is a DH02 version, which means the panel is made by AU Optronics. Our 55" has an original TH01 Samsung panel. The panel in our 60" was made by Sharp, and its version is MS01.

Upon testing, we found that each panel has a different contrast ratio. The 50" AUO (DH02) has the best contrast, at 4452:1, followed by the 60" Sharp (MS01) at 4015:1. The Samsung 55" panel had the lowest contrast of the three: 3707:1.

These results aren"t really surprising. All these LCD panels are VA panels, which usually means a contrast between 3000:1 and 5000:1. The Samsung panel was quite low in that range, leaving room for other panels to beat it.

The motion blur results are really interesting. The response time of the 55" TH01 Samsung panel is around double that of the Sharp and AUO panels. This is even consistent across all 12 transitions that we measured.

For our measurements, a difference in response time of 10 ms starts to be noticeable. All three are within this range, so the difference isn"t very noticeable to the naked eye, and the Samsung panel still performs better than most other TVs released around the same time.

We also got different input lag measurements on each panel. This has less to do with software, which is the same across each panel, and more to do with the different response times of the panels (as illustrated in the motion blur section). To measure input lag, we use the Leo Bodnar tool, which flashes a white square on the screen and measures the delay between the signal sent and the light sensor detecting white. Therefore, the tool"s input lag measurement includes the 0% to 100% response time of the pixel transition. If you look at the 0% to 100% transitions that we measured, you will see that the 55" takes about 10 ms longer to transition from black to white.

All three have bad viewing angles, as expected for VA panels. If you watch TV at an angle, most likely none of these TVs will satisfy you. The picture quality degrades at about 20 degrees from the side. The 60" Sharp panel is worse than the other ones though. In the video, you can see the right side degrading sooner than the other panels.

It"s unfortunate that manufacturers sometimes vary the source of their panels and that consumers don"t have a way of knowing which one they"re buying. Overall though, at least in the units we tested, the panel lottery isn"t something to worry about. While there are differences, the differences aren"t big and an original Samsung panel isn"t necessarily better than an outsourced one. It"s also fairly safe to say that the same can be said of other brands. All panels have minute variations, but most should perform within the margin of error for each model.
