Quick answer: Display panels come in several grades: original, original pulled or refurbished, OLED-type aftermarket, in-cell LCD and basic TFT. Each is a trade-off between picture quality, fit and cost. Junaid Telecom, Madrasa Banat Road, Chiniot, supplies Sunlong display panels for repair shops and technicians at wholesale rates.
Why is panel type so confusing?
Because the same word, “original”, means different things to different sellers. Two panels at very different prices might both be called “original” or “OLED” in a shop. The honest approach is to know the categories and ask what you are really getting. This guide is mainly for technicians and repair shops, but customers with a cracked screen can use it too.
What are the main display panel types?
| Type | What it is | Strengths | Limits |
|---|---|---|---|
| Original (new, genuine) | Made by or for the phone brand | Best match in colour, brightness and fit | Limited supply; not available for every model |
| Original pulled / refurbished | Genuine panel taken from a donor phone and reworked | Close to original quality | Condition varies; may have minor marks |
| OLED-type aftermarket | Third-party OLED-style panel | Deeper blacks and strong contrast | Quality differs between grades; power use and brightness may differ |
| In-cell LCD | LCD with touch layer integrated into the display stack | Thin, lower-cost replacement, wide availability | Black levels and colours usually weaker than OLED; may use more power |
| Basic TFT / IPS LCD | Simple LCD copy | Lowest cost | Weakest brightness and colour of the group |
Names and grades are not strictly standard across the industry, so always ask the supplier to explain their grade in plain words.
What is in-cell, exactly?
In an in-cell panel, the touch sensors are built into the LCD layers instead of sitting as a separate sheet. That allows a thinner display and lower manufacturing cost. As a replacement, in-cell panels are popular because they fit many models. The trade-off is that they are LCD-type, so blacks look greyer and contrast is lower than a true OLED, and some models lose features that rely on the original panel.
What should I know about OLED replacements?
OLED displays light each pixel individually, which gives deep blacks, strong contrast and often a thinner build. If your phone came with an OLED, an OLED-type replacement will feel closest to the original look. But quality varies widely between OLED grades in the aftermarket. Compare brightness, colour evenness and touch response, and be careful with extremely cheap OLED claims.
Phones with an in-display fingerprint sensor are an important case. These often depend on the original OLED stack, and a different panel type may reduce or remove the fingerprint feature. Ask before replacing.
How do I decide as a customer?
- Keep the same type if you can. If your phone has OLED, an OLED-type replacement is closest.
- Ask exactly what grade. Is it genuine, pulled, aftermarket or in-cell?
- Compare against your daily need. For a work phone, a lower-cost panel may be fine. For a flagship phone you love, spend more on quality.
- Check features. In-display fingerprint, high refresh rate and brightness may depend on the panel.
- Ask about the warranty. Warranty depends on the brand and the supplier; ask what is covered.
How should technicians test a panel?
Technicians should test before final assembly:
- Display test: look for lines, flicker, patches and dead pixels.
- Touch test: swipe edges and corners; look for ghost touch.
- Colour and brightness: compare against a known good panel.
- Face ID or fingerprint, proximity, rotation and auto-brightness sensors.
- Check for correct flex length and connector fit.
- Keep the original frame, adhesives and gaskets ready, and handle with ESD care.
What about Sunlong panels?
Sunlong (sunlongpk.com) is a mobile screen and display panel brand with an official authorized distributor in Pakistan. The brand promotes high brightness, vibrant colours and 120Hz panels. Junaid Telecom holds an official dealer letter from Sunlong and supplies Sunlong panels to repair shops and technicians. Which panel type is available for a given phone model changes, so WhatsApp the model name and ask exactly which grade you are getting before buying.
Why do repair shops buy panels wholesale?
Shops that repair many phones every week need steady supply and consistent grades. Buying wholesale from an authorized dealer gives:
- Predictable quality from one trusted source.
- Easy reordering for popular models.
- Support when a panel is found faulty, as per the brand’s warranty policy.
Technicians from Lalian, Bhowana, Jhang, Faisalabad and nearby towns can ask about stock and about sending it to their city.
Do I need a repair or just a protector?
A small crack on a screen with an intact display may only need a new tempered glass. A dead area, lines, ghost touch or bleeding colours usually means a panel replacement. The Repairing Lab on 0345 7599995 can inspect the phone and advise.
