There is provided a charge transport material which can easily be coated to form a film, is less likely to be crystallized during or after film formation, has excellent charge transport capability, and high applicability to electronic devices. The array is fabricated by forming discrete and self-aligned vias in a first layer disposed over the array to form contacts to each of the source and drain junction in the array. If the required instrument driver for the selected instrument is missing from the application development environment, an embodiment of the present invention retrieves the instrument driver from a remote location and installs the instrument driver in the application development environment without the involvement of the user. The second conversion material has a wavelength excitation spectrum, and at least some light from the LEDs passes through the second conversion material and is converted. The method also comprises the step of establishing a second difference between the obtained second quality value of the second channel with a second quality target value of the second channel and generating a second correctness target value.
