HIMX vs OLED: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
OLED is the larger of the two ($3.68B market cap): the incumbent the market prices for continued execution (16.64x forward earnings). HIMX is the smaller challenger ($2.19B), cheaper on forward earnings (12.54x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
HIMX vs OLED: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | HIMX | OLED | What it tells you |
|---|---|---|---|
| Market cap | $2.19B | $3.68B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 12.54 | 16.64 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 66.00 | 19.36 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Price vs 52-week range | 31% of range | 5% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 2.39 | 2.20 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: HIMX is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how HIMX and OLED affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. HIMX and OLED share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined HIMX and OLED exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Himax Technologies (HIMX) do?
Himax Technologies, Inc. is a fabless semiconductor company headquartered in Tainan, Taiwan, that designs display imaging chips and outsources their manufacturing to foundries. It reports in two segments: Driver IC (display driver integrated circuits and timing controllers that sit inside televisions, PC monitors, laptops, phones, tablets, ePaper devices, and, most importantly, automotive displays) and Non-Driver Products (which include its WiseEye ultralow-power AI sensing, LCoS microdisplays and wafer-level optics for AR smart glasses, and co-packaged optics for data centers). Himax is the global market-share leader in automotive display drivers, with roughly 40% share, and holds a large share in automotive TDDI (touch-and-display driver integration), which anchors the business to the long-run trend of larger, more numerous screens per vehicle.
What does Universal Display (OLED) do?
Universal Display Corporation (UDC) is the key intellectual-property and materials supplier behind OLED displays. OLED screens, used in premium smartphones, TVs, tablets, laptops, wearables, and increasingly automotive and AR/VR, light up each pixel directly without a backlight, enabling deep blacks, vivid color, and thin, flexible panels. Universal Display invents and patents the phosphorescent OLED (PHOLED) technology that makes these displays efficient, and it both licenses that IP to panel makers and sells the proprietary emitter materials (red and green phosphorescent emitters) those panels consume. This dual model means UDC earns recurring royalty and material-sales revenue every time a customer like Samsung Display or LG Display manufactures OLED panels. Headquartered in Ewing, New Jersey, Universal Display is essentially a high-margin licensing and chemicals business levered to the long-term growth of OLED adoption across consumer electronics.
HIMX vs OLED: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- HIMX drivers: Automotive display leadership; Non-driver AI and AR optionality.
- OLED drivers: OLED adoption expansion; Blue phosphorescent emitter.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The dominant risk is cyclicality and end-market concentration: display driver ICs are commoditizing and demand swings with the auto, TV, monitor, and smartphone cycles, so revenue and margins can fall quickly in a downturn. For OLED, universal Display depends heavily on a small number of large panel customers, especially Samsung Display and LG Display, so order timing and their capacity decisions drive results, making revenue lumpy.
HIMX or OLED: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick HIMX if you believe its drivers more; OLED if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the HIMX and OLED guides.
HIMX vs OLED: the full fundamentals
HIMX. Himax trades as a small-cap semiconductor ADR whose earnings are near a cyclical trough, so its trailing profit-based multiples look elevated even though revenue is large relative to its market value. The shares jumped sharply (nearly 38% in early trading) after the Q1 2026 beat and stronger Q2 guidance, a reminder of how volatile a small-cap cyclical can be around expectations. Because 2026 profit is depressed versus the company's own history, the stock is often framed on revenue, dividend yield, and non-driver growth potential rather than a single trailing P/E.
OLED. Universal Display is a high-margin, cash-rich IP-and-materials business with a clean balance sheet and a growing dividend. Its valuation reflects durable, recurring revenue from the OLED supply chain, balanced against customer concentration, display-cycle lumpiness, and long-term questions about patent duration and competing display technologies.
Headline figures (approximate, July 2026): HIMX shows revenue (q1 2026) ~$199.0 million (down ~2% sequentially and year over year), revenue (ttm) ~$830 million (rough run-rate off recent quarters), gross margin (q1 2026) ~30.4% (guided to ~32% for Q2 2026), net income (q1 2026) ~$8.0 million (~4.6 cents per diluted ADS); OLED shows revenue (ttm) ~$650 million, operating margin ~35%+, net margin ~30%+, gross margin ~75%+ (IP and materials).
The bottom line: HIMX vs OLED
HIMX and OLED are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined HIMX and OLED exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between HIMX and OLED?
+
Himax Technologies, Inc. Universal Display Corporation (UDC) is the key intellectual-property and materials supplier behind OLED displays. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is HIMX or OLED the better stock?
+
Neither is universally better. OLED is the larger incumbent; HIMX is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, HIMX or OLED?
+
On forward P/E (as of August 2026), HIMX trades at 12.54x and OLED at 16.64x, so HIMX is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both HIMX and OLED?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of HIMX vs OLED?
+
HIMX: The dominant risk is cyclicality and end-market concentration: display driver ICs are commoditizing and demand swings with the auto, TV, monitor, and smartphone cycles, so revenue and margins can fall quickly in a downturn. Himax is a small-cap ADR with meaningful customer and geographic concentration, and as a Taiwan-headquartered company with large China exposure it carries real geopolitical and supply-chain risk. As a fabless designer it depends on foundry capacity and pricing it does not control, which pressures gross margin. The newer non-driver bets (AI sensing, LCoS/AR optics, co-packaged optics) are promising but early, and may not scale into material revenue on the timeline the market expects. Finally, the dividend is set at roughly a full payout of trailing profit, so it can shrink if earnings weaken, and the ADS structure adds currency and reporting complexity versus a US operating company. OLED: Universal Display depends heavily on a small number of large panel customers, especially Samsung Display and LG Display, so order timing and their capacity decisions drive results, making revenue lumpy. Consumer-electronics demand cycles, particularly smartphone and TV sales, directly affect panel production and therefore UDC's royalties and material volumes. Key patents expire over time, and while the company continually files new IP, patent cliffs and licensing renegotiations are a structural risk. Competition in emitter materials and alternative display technologies (such as microLED) could erode its position over the long term. The stock can be volatile around display-cycle and blue-emitter news.
