Abstract: Provided are a display panel and an electronic terminal, including pixel units arranged along row and column directions. The pixel unit includes sub-pixels of different colors arranged along the row direction. In a first mode, two adjacent groups of pixel units are simultaneously turned on, and the sub-pixels of a same color in two adjacent columns of pixel units display a same gray scale. In a second mode, a plurality of rows of pixel units are turned on sequentially, and each sub-pixel in a plurality of columns of pixel units displays a corresponding gray scale. The refresh rate of the first mode is greater than that of the second mode, and the resolution of the first mode is smaller than that of the second mode. This shortens the time required for all rows of pixel units to be turned on, thereby increasing the refresh rate.

Abstract: A TFT array panel includes a primary display area and a slitting-edge display area. In the slitting-edge display area, a first metallic routing layer includes a first data line and a second metallic routing layer includes a first gate line. The first data line is connected to the second metallic routing layer through a hole in the interlayer dielectric layer so that the first data line overlaps the first gate line to form an overlapping capacitance to compensate for a gate line RC value.

Abstract: A demultiplexer and a display device are provided. The demultiplexer is connected with a scanning driving circuit, and the scanning driving circuit includes multiple scanning driving units connected sequentially. The demultiplexer includes a control signal unit for outputting a first group of control signals and a second group of control signals, and a switching unit including a first switching group and a second switching group. When odd rows of the scanning driving units output scanning signals, the first group of control signals controls the first switching group to be turned on to charge the pixel unit. When even rows of scanning driving units output scanning signals, the second group of control signals controls the second switching group to be turned on to charge the pixel unit in order to decrease a refresh rate of the first group of control signals and the second group of control signals.

Abstract: The present disclosure relates to an array substrate and the manufacturing method thereof. The array substrate includes a glass substrate. The shading metal layer and the buffering layer are formed on the glass substrate in sequence. The TFT layer is formed on the buffering layer, and the TFT is arranged above the shading metal layer. The insulation layer and the organic layer are formed on the TFT layer in sequence. In addition, the pixel electrode layer connects to the source/drain of the TFT via the first through hole. The touch electrode layer connects to the shading metal layer via the second through hole. The passivation layer is configured between the pixel electrode layer and the touch electrode layer. In this way, the manufacturing process is simplified, and the coupling capacitance between the touch electrode and the signal line may be effectively reduced.
