Claim:
1. A quality test device for testing a display device having a plurality of thin film transistors TFTs, the display device configured to be disposed in a vehicle, the quality test device comprising: a color analyzer determining a color of an image displayed by the display device; and a quality inspection module controlling the display device to a predetermined display state and determining whether the TFTs are adequately disposed within the display device based on a performance threshold stored in a computer readable medium, wherein the color analyzer determines a color of the image displayed by the display device when the display device is controlled to the predetermined display state, the quality inspection module calculates performance data based on the color detected by the color analyzer and a test parameter associated with the performance threshold, the quality inspection module determines that the display device is defective when the performance data is outside of the performance threshold, and determines that the display device is normal when the performance data is within the performance threshold, the quality inspection module controls the display device to a first state and a second state, and the predetermined display state includes the first state and the second state, the color analyzer detects a first color of an image displayed by the display device when the display device is controlled to the first state and detects a second color of an image displayed by the display device when the display device is controlled to the second state, the quality inspection module calculates the performance data based on the first color, the second color, and the test parameter, the quality inspection module toggles the TFTs in an ON-OFF pattern to control the display device to the first state and toggles the TFTs in an OFF-ON pattern to control the display device to the second state, and wherein:
