    摘要: A backlight module and a display device having same are disclosed. The backlight module comprises a plurality of backplanes that are combined. A plurality of light emitting units are disposed on the backplane for emitting light under control of power source high potential signals and power source low potential signals. The light emitting units include first light emitting units that are located in a combining area of adjacent backplanes and second light emitting units that are located in other areas of the backplanes. On at least one of the backplanes, intensity of first power source high potential signals corresponding to the first light emitting units is greater than that of second power source high potential signals corresponding to the second light emitting units.

    摘要: The present disclosure discloses a backlight driving circuit and a display device. The backlight driving circuit includes a power supply chip, light-emitting diodes connected to the power supply chip, and a voltage protection sub-circuit connected to both the light-emitting diodes and the power supply chip. By adding the voltage protection sub-circuit, when a negative terminal voltage of the light-emitting diode is abnormal, the voltage protection sub-circuit will output a feedback signal to the power supply chip to stop the power supply chip from working, thereby improving reliability of the backlight driving circuit.

    摘要: A gate driving circuit and a display panel are provided. The gate driving circuit reduces the number of transistors through the inverter in the pull-down maintaining circuit such that the number of the signal output ends connected to the inverter is reduced. In this way, the number of the other transistors in the pull-down maintaining circuit is also reduced. Therefore, the number of the transistors and the number of the signal output ends of the pull-down maintaining circuit are both reduced. This means that the number of the transistors and the number of the signal output ends of the gate driving circuit are both reduced.

    摘要: A touch panel provided by the present invention includes light sensitive circuits and a touch circuit. The light sensitive circuits include a readout line disposed along a second direction. The touch circuit includes signal emitting lines disposed along a first direction and signal receiving lines disposed along a second direction. Wherein, the signal emitting line, a scanning line, and a gate electrode are disposed on a same layer, and the signal receiving line, a readout line, and a source/drain electrode layer are disposed on a same layer. No additional film layer is added, integrating the light sensitive circuits and the touch circuit in one touch panel.

    摘要: The present disclosure provides a display panel including gate lines and data lines disposed on a base substrate. The base substrate is further divided into pixel regions including transparent regions and pixel circuit regions having pixel circuits. The pixel circuit regions of at least two adjacent pixel regions are disposed next to each other and form a pixel circuit joining region, so that the pixel circuit regions of a same row or a same column of the pixel regions are arranged spaced apart from each other. Two adjacent pixel circuit joining regions are spaced apart by the transparent regions.
