Have you ever been at the car wash in the late afternoon, struggling to read the instructions on the display at the pay kiosk? That may be because it was not a sunlight-readable<\/a> LCD<\/a> display.<\/p>\n

What Makes a Display Readable in Bright Light?<\/h3>\n

There are two ways to get sunlight readability: 1) is to work with the sun, and 2) is to overpower the sunlight.<\/p>\n

1) LCDs that Work With the Sun<\/h3>\n

Any character or graphic LCD (not TFT<\/a>, we will get to that in a bit) that is “positive mode” will be sunlight readable. Positive mode displays will have dark letters on a light background<\/em>.<\/p>\n

Examples of positive mode displays:<\/p>\n

With these modules, more<\/em> light gives better readability.<\/p>\n
