Oppo Reno7 lineup’s LDI design process detailed ahead of February 4 global launch


Introduced in China in November, the Oppo Reno 7 series will begin its global journey on February 4, starting with India. The lineup is Reno7, Reno7 SE, Reno7 Pro. We know that the Pro model will be available in India, but the company hasn’t confirmed whether to bring both the vanilla and SE versions to Asian countries or skip one.

While waiting for more Reno 7 phones to be launched in India next week, Oppo elaborated on the LDI technology design process found in the global models of the Reno 7 series.

LDI, short for Laser Direct Imaging, is used in the aviation industry to design PCBs. Also, according to Oppo, engineers reused “aircraft grade” LDI for three years. It is used to create 1.2 million microetches with a width of 20 microns across the surface of the back panel of a smartphone.

This gives the back cover of the mobile phone the visual and textured illusion of a shooting star, which Oppo calls “aircraft-grade shooting star design.” In addition, micron-scale etching helps Oppo achieve a matte brush finish on top of the Oppo Glow layer. This is the rebranded Reno Glow design I saw on the Oppo Reno 6 Pro last year.

The first step in the LDI process is to coat the glass side facing the phone with a layer of UV protective ink to prevent it from being chemically etched in later steps. This protective layer also helps improve the accuracy of laser engraving due to its light absorption properties.

After this, the surface opposite the glass facing the user is coated with a photoresist layer to create the desired star trail pattern on the Reno 7 series. This gives you a “dynamic optical effect” when you look at the phone from different angles.

Oppo also tells us a bit about the camera module on the back panel of the phone. The island design is called the Twin Moon Camera Design, with the upper half decorated with metal and the lower half coated with ceramic, “providing a contrasting yet premium experience.”

The LDI design process for the Oppo Reno 7 lineup is detailed prior to its global launch on February 4th.

According to the phone maker, the Reno7 Pro features the company’s first zirconia color-ceramic plated lens bezel. Zirconia has a hardness of 8.5 compared to 5.5 in stainless steel and is coated with another harder, slightly protruding film to protect the surrounding lens, keeping it safe from scratches.

What’s more, the Reno7 Pro’s camera module has a breathing light around it, and Oppo uses bent 1mm diameter fibers to frame the camera area. This fiber emits a soft, pulsating light when your smartphone is charging or receiving a call or message.

Oppo has also confirmed that the international Reno 7 Pro will have a 4,500mAh battery similar to its Chinese counterpart. The smartphone also has an aluminum frame and has a 2.5D rounded design that fits comfortably in the hand. However, with these flat edges, we still don’t know how comfortable the Reno7 Pro can hold.

Oppo hasn’t elaborated on the global Reno 7 Pro spec sheet yet, but the company has already confirmed that it comes with a Dimensity 1200-MAX SoC, 65W charging, and Wireless PC Connect. The smartphone is 7.45 mm thick and is equipped with Sony’s IMX709 sensor and IMX766 sensor.

We look forward to more details on the Reno 7 series, which will be released worldwide next week, and this way you can see the detailed specifications of the Reno 7 lineup available in China.
