The embodiment of the invention disclose an array substrate and an electronic paper display device. The array substrate includes a plurality of data lines arranged in the first direction and extendingin the second direction, and a plurality of scan lines arranged in the second direction and extending in the first direction, wherein the first direction intersects with the second direction; in thefirst direction, the data lines are continuously divided into multiple sets of data line groups, the data lines in the same data line group are electrically connected to each other, each set of the data line group is electrically connected to a driving circuit located in a non-display area through a fan-out line, the data line groups are arranged in the direction from the middle of a display areato the two sides, the number of the data lines in the latter set of the data line group is less than or equal to the number of the data lines in the previous set of the data line group, and the numberof the data lines in at least one data line group is smaller than the number of the data lines in the adjacent data line group. The array substrate improves the problem of data line resistance mismatch, and achieves a narrow frame design of an ultra-long electronic paper.

The present invention relates to a conductive paste and a solar cell. The conductive paste contains a conductive powder, including at least a silver powder, a glass frit composed mainly of Te, Bi and Zn, and an organic vehicle. The total molar quantity of the three components of Te, Bi and Zn contained in the glass frit is, in terms of oxide, set at 95 mol% or more. Light-receiving surface electrodes (3) are formed by using the above-conductive paste. Thereby, a conductive paste suitable for forming solar cell electrodes is achieved, the conductive paste being capable of reducing both of the contact resistance between the electrodes and the semiconductor substrate, and the line resistance of the electrodes, while being lead free. Furthermore, a solar cell having high energy conversion efficiency and excellent battery characteristics is achieved as a result of using the conductive paste.

A power line resistance sensing device adapted to a lamp system with an LED module connected to a power supply between a supply line and a ground line. The power line resistance sensing device includes a control unit including a first pin connected to an LED switch to turn on or turn off the LED module; a second pin connected to a testing switch to fire a testing current from a testing current source into the lamp system before a full conduction of the lamp system; and a third pin used to receive a voltage drop induced by the testing current fired in the lamp system. The control unit is configured to compare the voltage drop with a predetermined safety voltage drop, thereby controlling the LED switch.
