Display Panel Oversupply, Not Weak Demand, Is Fueling the Refurbished Market

The increase in replacement and refurbished display panel volumes is not a demand-side signal about consumers shifting to secondhand phones. It is a supply-side symptom of Chinese LCD panel makers unable to place their output with primary smartphone OEMs as those OEMs migrate to OLED. When the main channel closes, the panel has to go somewhere. The aftermarket absorbs the overflow.

The Two-Market Split in Smartphone Displays

The smartphone display market has bifurcated into two distinct sub-markets that are moving in opposite directions. Treating them as a single market obscures what is happening.

OLED is the tight market. AMOLED display shipments for smartphones surpassed TFT LCD shipments for the first time in 2024, according to Omdia, and the gap has widened since. Apple, Samsung, and premium Chinese brands are now overwhelmingly OLED. Capacity in Gen 8 OLED lines is booked years ahead for iPhone and Samsung flagship orders. LG Display reported that OLED products reached 61 percent of its total revenue in fiscal 2025, up from 55 percent in 2024 and 32 percent in 2020.

LCD is the oversupplied market. Omdia projects small and medium display shipments to decline 19 percent year-over-year in the first half of 2026. In Q2 2025 alone, shipments fell an estimated 10 percent quarter-on-quarter as device makers reset bloated inventories. Global smartphone shipments grew only 2 percent in 2025 and Omdia now forecasts a 12 percent decline in 2026, with the contraction hitting entry-level models - the last holdouts for LCD - hardest.

The constraint has migrated. On the OLED side, the question is who has allocated substrate capacity (the monthly throughput of glass panels that are then cut into individual displays). On the LCD side, the question is what happens to the excess panels that no primary OEM will buy.

Panel Maker Financials Confirm the Split

The financial performance of the major display manufacturers maps directly to this bifurcation. The industry's six largest panel makers posted their strongest results in years in 2025, but the winners and losers separate cleanly along the OLED-LCD divide.

Samsung Display generated approximately $3.2 billion in operating profit on roughly $23 billion in revenue in fiscal 2025 - an operating margin near 14 percent. OLED is Samsung Display's core business. The company has not needed to pivot; it has been positioning ahead of the shift since the iPhone X.

LG Display tells the turnaround story. Revenue reached $19.8 billion in fiscal 2025 with net profit of $360 million, its first full-year profit in four years. But the critical detail is what the company has been exiting. LG Display completed the sale of its Guangzhou LCD plant stake to TCL CSOT for approximately $1.5 billion. Its Gen 8 OLED utilization ran at roughly 75 percent, using about 135,000 of its 180,000 monthly substrates. The 2026 capex budget of approximately $1.4 billion is directed entirely to OLED. The stock, listed on the NYSE as LPL, is down 23 percent year-to-date despite the turnaround - trading at $3.23 with a debt-to-equity ratio of 178 percent and negative free cash flow of $341 million over the trailing twelve months. The balance sheet tells a different story from the income statement: OLED capex remains capital-intensive and the leverage is high.

On the LCD side, BOE Technology reported 2025 first-nine-month revenue of $21.5 billion with a net profit margin near 3 percent. The scale is enormous but the margins are thin - a function of LCD being a commodity business where pricing power has eroded. BOE's NYSE-listed ADRs trade at $12.27 and have returned roughly 5 percent year-to-date. Visionox, the smallest of the six and an OLED-focused player, posted nine-month losses of $225 million.

The pattern is clear: OLED leaders command pricing power. LCD incumbents operate on volume and margin compression. The companies that have exited LCD - or are in the process of doing so - are the ones posting durable profitability.

What the Refurbished Display Spike Actually Measures

This is where the refurbished market enters the picture. The global refurbished smartphone market is growing at an estimated 7 to 11 percent CAGR depending on the research house, reaching $70 billion in 2026 and projected to approach $186 billion by 2032. Display replacement is the single largest repair category for smartphones - display issues account for the majority of physical damage claims across all repair networks.

But the surge in refurbished-market display shipments is not evidence of a booming demand story for secondhand phones. It is evidence of LCD panel capacity that has no other buyer. When Samsung, Apple, Xiaomi, and vivo move their entry-level and mid-range models to OLED or reduce LCD volume, the panels produced on existing LCD lines do not simply stop being made. LCD fabs run at fixed capacity with enormous sunk costs. The alternative to shipping a panel at a discount is writing it off entirely.

The aftermarket channel - repair shops, refurbishers, third-party replacement kit distributors - becomes the price floor for LCD output. A panel maker would rather sell a 6.5-inch LCD panel to a refurbisher at a low single-digit dollar price than scrap it at zero. That transaction shows up as "growth in refurbished display shipments." It does not show up as a demand-driven tailwind.

The distinction matters because demand-driven growth is margin-expanding and supply-driven dumping is margin-compressing. For the companies selling into the refurbished channel, this volume growth carries none of the profitability that primary OEM sales do. For the LCD panel makers sourcing it, the aftermarket is a loss-minimization channel, not a growth strategy.

The Implication for the Cycle

Omdia also reported that June 2026 mobile phone panel shipments increased 7 percent month-over-month to 206 million units, suggesting a modest rebound. But the structural direction has not changed. LCD panel capacity remains the residual inventory the market must work through.

The supply discipline that carried the display industry through its 2022-2023 downturn - when panel makers collectively cut production and prices collapsed - has partially eroded on the LCD side. The Korean companies exited LCD. The Chinese companies, backed by state industrial policy and unable to repurpose LCD lines, continue running them. The excess capacity flows into the channels with the weakest pricing power: low-end OEMs, replacement markets, and refurbished assemblers.

That relationship has now changed from what it was in the last cycle. LCD is no longer a business where capacity can be curtailed to restore pricing. It is a business where capacity must be utilized to service debt and cover fixed costs, and the aftermarket is the buyer of last resort.

Investor Takeaway

The key issue is not whether the refurbished smartphone market continues to grow. It will. The more important question is whether LCD panel capacity runs down fast enough to stop feeding the aftermarket before the primary smartphone OEM market begins recovering.

For investors, the practical implication is that display panel companies should be evaluated by their OLED exposure, not their total panel volume. LG Display's OLED pivot is real but fragile - its balance sheet is leveraged and its free cash flow is negative. Samsung Display is the cleanest position. BOE's scale masks margin erosion. Any panel maker whose revenue mix remains LCD-heavy is structurally exposed to continued aftermarket dumping and pricing pressure.

The refurbished display shipment story is a headline about supply overflow wearing the costume of demand. When smartphone OEM volumes recover and LCD capacity has not yet retired, the aftermarket may continue to grow even as LCD prices stay depressed. The signal to watch is not refurbished shipment volumes. It is LCD fab utilization rates and whether any additional LCD line closures materialize.
