    Abstract: A pixel arrangement structure includes a plurality of pixel repeating units arranged in a matrix in a row direction and a column direction. Each of the plurality of pixel repeating units includes a first pixel unit and a second pixel unit sequentially arranged in the column direction. The first pixel unit includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel which are sequentially arranged in the row direction. The second pixel unit includes a third sub-pixel, a fourth sub-pixel, a first sub-pixel, and a second sub-pixel which are sequentially arranged in the row direction. Each column of sub-pixels is divided into a first subset of sub-pixels connected to a first data line and a second subset of sub-pixels connected to a second data line.

    Abstract: The embodiments of the present disclosure propose a device for inspecting a mask plate, a method for inspecting a mask plate, and a corresponding method for controlling light sources. The device includes: an image sensor configured to capture an image of the mask plate; and a plurality of light sources disposed on one side of the mask plate opposite to the image sensor, wherein at least one of the plurality of light sources is configure to emit light when the image sensor is capturing an image of a first region of the mask plate, and the at least one light source comprises light sources within a first range, wherein the first range corresponds to the first region and an orthographic projection of the image sensor on a light source plane falls within the first range. The method for controlling light sources includes: turning on at least one of a plurality of light sources disposed on one side of the mask plate opposite to an image sensor, which corresponds to a first region of the mask plate to be inspected, when the image sensor is moved to a position corresponding to the first region.

    Abstract: The present disclosure provides a display device. The display device includes a first substrate, the first substrate being provided with a first relief groove, a second substrate, the second substrate being provided with a second relief groove, and a sealant. The sealant is sandwiched between the first substrate and the second substrate so as to seal the first substrate and the second substrate. Furthermore, the sealant is spaced apart from outer edges of the first substrate and the second substrate. The first relief groove is located between the sealant and the outer edge of the first substrate, and the second relief groove is located between the sealant and the outer edge of the second substrate.

    Abstract: A pixel circuit and a display device are provided. The pixel circuit includes: a first inverter circuit having an input terminal connected to a first node and an output terminal connected to a second node; a second inverter circuit having an input terminal connected to the second node and an output terminal connected to a third node; a first switching circuit configured to disconnect a connection between the first node and the third node when a first scanning signal is at an active level; and a control circuit configured to control a level of at least one of the first node and the second node according to a level control signal when the first scanning signal is at an active level. Based on this, it can help to avoid the output signal abnormality of the latch inside the pixel and enhance the working stability of the pixel circuit.
