The invention provides a display panel. The display panel comprises a first gate line driving circuit and a second gate line driving circuit, which are respectively arranged on two sides of a display area, and controls the same pixel in the display area via a first gate line and a second gate line. The first gate line driving circuit is electrically coupled to the first gate line so as to provide a first control signal to the first gate line. The second gate line driving circuit is electrically coupled to the second gate line so as to provide a second control signal to the second gate line. In addition, the second gate line driving circuit is electrically coupled to a luminance control line so as to provide a luminance control signal to the luminance control line and control the same pixel to emit light at any time via the luminance control line. According to the invention, a gate control signal generator is divided into two areas, so uniformity of luminance of the display panel is better, and poor display effects caused by influences on normal operation of circuits due to errors in manufacturing technique are avoided.

The invention discloses a sunshine room roof leakage-proof method. Primary drainage channels and secondary drainage channels are formed in primary beams and secondary beams, and leakage holes are formed in the secondary drainage channels of the primary beams and communicated with the primary drainage channels. Drainage channel openings of the primary drainage channels of the secondary beams are higher than drainage channel openings of the primary drainage channels of the main beams, and a large amount of rainwater is freely drained from top to bottom. During second drainage, bearing bosses are formed on the outer side walls of the secondary drainage channels of the primary beams and the secondary beams, rubber channels are formed in bearing surfaces of the bosses, waterproof rubber is mounted in the rubber channels, glass is pressed on the waterproof rubber by the aid of weight, and the rainwater is stopped at the secondary drainage channels by the waterproof rubber and guided into the secondary drainage channels of the primary beams. The rainwater flows into the primary drainage channels through the leakage holes in the secondary drainage channels of the primary beams and is smoothly drained. The invention further discloses a sunshine room roof structure. Organized drainage is realized, roof leakage is effectively avoided, wires and pipes are distributed, the cost is low, and the heat insulation effect is fine.
