TM070JDHG30 TIANMA 7.0 inch 1280x800 WXGA TFT LCD Panel

TM070JDHG30 Overview

The TIANMA TM070JDHG30 is the series-level writing of the 7.0 inch 1280 x 800 module; the -00 suffix is added on purchase orders that record a revision. Design files often carry only the series code, which is why service departments and procurement systems still ask for it by this name.

Physically it is the same thin panel: 149.76 x 93.60 mm active area, 3.35 mm back, 40-pin single-channel LVDS, 400 cd/m2 and 800:1 contrast. Those figures make it a natural fit where a WVGA panel has run out of space for tables, waveforms or small icons but the window cannot grow.

Key Characteristics

• Series code for legacy documentation: matches drawings and bills of material written before revision suffixes were enforced

• 1280 x 800 resolution: four times the pixel count of QVGA and about double WVGA, so dense process screens stay readable

• 3.35 mm profile: fits flat front panels and hand-held housings without a spacer ring

• Single LVDS channel: one 40-pin connector, short cable, no dual-channel transmitter on the host

Technical Specifications

Typical Applications

• Panel PCs and front panels: machine terminals upgraded from WVGA without changing the window

• Portable test equipment: analysers and field instruments that need fine detail in a small housing

• Medical review terminals: compact monitors for waveform and image review

• Replacement stock: service kits where the original label reads TM070JDHG30 without a suffix

Integration Notes

Because the module has no scaler, the host must output 1280x800 at 60 Hz. A source set to 800x480 shows a cropped image or a black screen, which is often mistaken for a dead panel during commissioning.

Keep the 40-pin tail short and route the pairs as 100 ohm differential lines. The panel dissipates about 1.9 W, so in a sealed enclosure provide a metal or graphite path to the frame; the +70 degC limit is a cell temperature, not a room temperature, and is reached faster than most designers expect.

Quality Inspection

Screening is done at native resolution with fine-line patterns, then repeated after a short burn-in to catch driver IC faults that only appear warm. The tail is flexed once, the connector inspected, and the 3.35 mm outline checked against a gauge before packing.

Packing and Shipping

Modules are packed flat between foam sheets, forty per carton of 530 x 350 x 288 mm. Each bag carries the model code and the revision found on the label, and cartons are marked fragile with a stack-height limit.

FAQ

How do I know whether I need TM070JDHG30 or TM070JDHG30-00?
They are the same panel. Read the label on the module in the machine: if it shows the suffix, quote the full number; if only the series code is printed, either writing will supply the same build.

Does the module include a touch sensor?
No. It is display only; a separate overlay is needed for touch, and the 3.35 mm back leaves little room for an integrated sensor stack.

Which backlight driver is required?
The 21-LED string runs at 9.3 V and 140 mA and has no on-board driver, so an external constant-current supply is required. Fixed-voltage drive causes brightness drift and shortens LED life.

Is the panel suitable for portrait mounting?
The viewing cone is symmetrical at 88/88/88/88, so rotation is optically acceptable. Mechanically, confirm that the tail and connector stay clear of the new bottom edge.

Can you supply a matching LVDS cable?
We can quote a cable built to your pin-out and length. Send the host connector type and the distance inside the cabinet, and we will confirm the pair mapping before assembly.
