7 Inch Display Guide: 800 × 480 vs 1024 × 600, RGB, LVDS or MIPI
A 7 inch display in an embedded product is usually a landscape TFT at 800 × 480 or 1024 × 600, with about 154 × 86 mm of active area in a module body near 165 × 100 mm. The interface is parallel RGB when the host is close and has an LCD controller, LVDS when the cable is long or the processor has an LVDS output, and MIPI DSI on newer processors. In our catalogue three 7-inch references share one 164.8 × 99.8 mm body: 800 × 480 RGB, 1024 × 600 RGB and 1024 × 600 LVDS. One enclosure opening can take any of them.
How big is a 7 inch display?
The 7 inches is the diagonal of the active area: 177.8 mm. What you have to fit is the module, which is bigger. On S700MI2XE-02 the active area is 154.21 × 85.92 mm. Pythagoras gives a diagonal of 176.5 mm, or 6.95 inches, so the nominal size is rounded up slightly, as it usually is.
| Item | Active or viewable area | Outline | Source |
|---|---|---|---|

| S700MIWN-18-W and S700MB1XH-09 | See drawing | 164.8 × 99.8 mm | Product JSON-LD |
| S700MIWE-28C0, touch assembly | See drawing | 164.9 × 100 mm | Product JSON-LD |
| Raspberry Pi Touch Display, 800 × 480 | 154.08 × 85.92 mm viewable | 192.96 × 110.76 mm with metal frame | Raspberry Pi documentation |
| Raspberry Pi Touch Display 2, 7-inch, 720 × 1280 | 87 × 154.5 mm active (portrait) | 120 × 189.5 × 15 mm | Raspberry Pi documentation |
Notice how much the finished accessories grow around the same glass. A bare module is the smallest thing you can design around; a boxed display with its own frame and driver board adds about 25–28 mm along the long side.
The 7-inch references
| Reference | Resolution | Interface | Touch | Body (W × H) |
|---|---|---|---|---|
| S700MIWN-18-W | 800 × 480 | RGB | None fitted | 164.8 × 99.8 mm |
| S700MI2XE-02 | 1024 × 600 | 24-bit RGB, 50-pin FPC at 0.50 mm pitch | None in the drawing | 164.8 × 99.8 mm, 5.50 mm thick |
| S700MB1XH-09 | 1024 × 600 | LVDS | None fitted | 164.8 × 99.8 mm |
| S700MIWE-28C0 | See drawing | See drawing | Capacitive | 164.9 × 100 mm |
| S700GG-42 | Touch panel only | I²C, GT911 controller | Capacitive | 164.4 × 99.5 mm |
The shared outline is the useful part. A product family can have an 800 × 480 entry model and a 1024 × 600 model in the same housing, and if the electronics later move to a processor with LVDS, the opening still fits. The FPCs and pin assignments differ, so the board connector changes; the mechanical design does not. S700GG-42 and S700GF2-05 are standalone 7-inch capacitive panels for when the touch sensor is bought separately from the display.
800 × 480 or 1024 × 600?
| 800 × 480 | 1024 × 600 | |
|---|---|---|
| Pixels | 384,000 | 614,400 (1.6 ×) |
| Frame buffer, 16-bit colour | 768,000 bytes | 1,228,800 bytes |
| Frame buffer, 24-bit colour | 1,152,000 bytes | 1,843,200 bytes |
| Typical timing at 60 Hz (published 7-inch datasheets) | 928 × 525 total, 29.2 MHz | 1344 × 635 total, 51.2 MHz |
| Usual host | Microcontroller with an LCD controller and external RAM, or a processor | Application processor, or a high-end microcontroller |
The timings come from Newhaven’s 7-inch 800 × 480 RGB and 1024 × 600 LVDS datasheets; use the ones in your own panel’s datasheet, and the pixel clock and bandwidth calculator for the sums. Going from 800 × 480 to 1024 × 600 costs 60 % more memory and about 75 % more pixel clock, because the larger panel’s blanking is longer too. If the interface is big tiles and numbers read from a metre away, 800 × 480 is enough. Text-heavy screens, trend graphs and maps are where 1024 × 600 earns its keep.
The pixels on a 7-inch 1024 × 600 panel are not square
This one catches software teams. Divide the S700MI2XE-02 active area by the pixel counts: 154.21 ÷ 1024 ≈ 0.1506 mm across and 85.92 ÷ 600 ≈ 0.1432 mm down. The pixels are about 5 % wider than they are tall.
Worked example: a round gauge. A circle drawn 300 pixels wide and 300 pixels tall comes out 300 × 0.1506 ≈ 45.2 mm wide and 300 × 0.1432 ≈ 43.0 mm tall. That is visibly oval on a dial, a logo or a round button. Scale the vertical size by 0.1506 ÷ 0.1432 ≈ 1.05 and draw it 300 pixels wide and about 315 tall. Photos and icons from designers working on square-pixel monitors need the same correction.
Run the same check on any 800 × 480 panel before the graphics are drawn. It takes a minute.
RGB, LVDS or a 7 inch MIPI display
RGB (S700MIWN-18-W, S700MI2XE-02) is the simple option for a host with a parallel LCD controller: up to 24 data lines plus clock, HSYNC, VSYNC and DE, 28 signals in all. At 51 MHz across a wide bus it radiates, so keep the FPC run short and the display next to the board.
LVDS (S700MB1XH-09) carries the same image on four differential data pairs and a clock pair. Use it when the display sits in a lid, a door or a separate panel, when EMC margins are tight, or when the processor already has an LVDS output.
A 7 inch MIPI display is a different animal. Many are portrait panels made for phones and tablets; the Raspberry Pi Touch Display 2, for example, is 720 × 1280 on DSI. We have no 7-inch MIPI reference in the catalogue today. If your processor has DSI and you want a landscape 7-inch module, a DSI-to-LVDS bridge in front of S700MB1XH-09 is one route: TI’s SN65DSI83 accepts one to four lanes at up to 1 Gbit/s each and drives single-link LVDS at 25–154 MHz, which covers a 51 MHz 1024 × 600 timing. The MIPI DSI interface guide explains how to check the lane budget.
7 inch HDMI and Raspberry Pi displays vs. a product display
A 7 inch HDMI display is a TFT panel with a driver board that receives HDMI and converts it to the panel’s RGB or LVDS timing. It is a good way to put a user interface on a bench in an afternoon. In a product, that board adds height, power and a second supply chain, and most embedded processors can drive the panel directly anyway.
Raspberry Pi’s own 7-inch displays are popular development screens. The original Touch Display is 800 × 480 with ten-point touch and connects over DSI. Touch Display 2 is 720 × 1280 with five-point touch, natively portrait. If you prototype on one and plan to build on a 1024 × 600 landscape module, the user interface has to be laid out again, not just scaled: different aspect ratio, different orientation and, as above, possibly non-square pixels.
Bezel opening and touch
The drawing of S700MI2XE-02 gives a bezel opening of 156.70 × 89.10 mm, about 1.2–1.6 mm larger than the active area on each side. That margin is there so the edge pixels stay visible at an angle. Cut the enclosure window to the active area exactly and the outer columns disappear behind the frame when someone looks from the side. With capacitive touch, the cover lens usually becomes the visible front, printed with a black border instead. For gloves or water on the glass, see capacitive touch with gloves, water and thick glass; for how the sensor is built, see capacitive touch panel structures.

7 Inch Display FAQs
How big is a 7 inch display?
The 7 inches is the diagonal of the active area, about 177.8 mm. A typical 7-inch 1024 × 600 module such as S700MI2XE-02 has an active area of 154.21 × 85.92 mm and a body of 164.8 × 99.8 mm, so allow for the module outline, not just the diagonal.
What resolution is a 7 inch display?
Most 7-inch modules for embedded products are 800 × 480 or 1024 × 600 landscape. Our references cover 800 × 480 RGB, 1024 × 600 RGB and 1024 × 600 LVDS in the same 164.8 × 99.8 mm body. Phone-style 7-inch MIPI panels are often portrait, such as 720 × 1280.
Should a 7 inch display use RGB or LVDS?
Use RGB when the display is close to a host with a parallel LCD controller. Use LVDS for longer cables, displays in lids or doors, EMC-sensitive products, or a processor with an LVDS output. At 1024 × 600 a 24-bit RGB bus runs at about 51 MHz on 28 lines, which is hard to keep quiet over a cable.
Can I use a 7 inch HDMI display in a product?
You can, but it brings a driver board that adds height, power and another part to keep in supply. Most embedded processors can drive an RGB, LVDS or MIPI panel directly, so HDMI displays are usually kept for prototypes and test benches.
