    Abstract: A pixel circuit, an organic electroluminescent display panel and a display device in a reset and compensation phase, a charge control module of the pixel circuit makes a data signal end and the first input end of a reset control module switch on, and the reset control module resets the control end and a output end of a drive module and compensates reference voltage; in a data writing phase, the charge control module writes the data signal inputted by the data signal end to the first input end of the reset control module; in a light-emitting phase, a light-emitting control module makes the output end of the drive module and the input end of the light emitting device switch on and drives the light emitting device to emit light by integrating the data signal inputted into the drive module with the reference voltage signal compensated into the drive module, which realizes the effect that the drive current driving the light emitting device to emit light is irrelevant to the power supply voltage signal, eliminates the influence on luminous brightness of the light emitting device caused by IR drop of the power supply voltage signal inputted into the pixel circuits, and further guaranteeing the display effect of the display panel.

    Abstract: An OLED pixel circuit includes a charging control module (1), a resetting control module (2), and a driving transistor (3). The charging control module (1) is connected to a data signal line and the resetting control module (2). The resetting control module (2) is connected to the driving transistor (3) to reset and compensate the driving transistor (3) to set a control terminal of the driving transistor (3) at a first potential value. The driving transistor (3) is configured to generate a driving current being based on a difference between a potential of a source of the driving transistor and the first potential value, irrespective of a voltage signal at the source of the driving transistor and a threshold voltage of the driving transistor (3).

    Abstract: An array substrate and a display device are disclosed. The array substrate (01) comprises a gate electrode driving circuit (10), the gate electrode driving circuit (10) includes at least two stages of shift register units (SR1-SRn), and each stage of the shift register units (SR1-SRn) is connected with a row of gate lines (Gate1-Gaten). The shift register units (SR1-SRn) include driving modules (D1-Dn) and logical modules (L1-Ln); the driving modules (D1-Dn) include a portion located in a display region (100) of the array substrate. The array substrate can solve a problem that a larger size of a driving TFT in a gate driver on array (GOA) circuit is not conducive to a narrow frame design trend of a display panel.

    Abstract: A liquid crystal grating and a manufacturing method and a driving method therefor, and a spliced screen including a liquid crystal grating are disclosed. The liquid crystal grating includes: a first substrate and a second substrate arranged opposite to the first substrate; and liquid crystal molecules filled between the first substrate and the second substrate. The first substrate, the second substrate and the liquid crystal molecules are provided to define at least one grating unit. Each of the grating units includes: a display region; a frame region surrounding the display region; a first frame electrode located on the first substrate and arranged corresponding to the frame region; and a second frame electrode located on the second substrate and arranged corresponding to the frame region. The first frame electrode and the second frame electrode are configured for forming a voltage difference when displaying in the display region, so as to control deflection of the liquid crystal molecules in the frame region, such that light rays scattered into the frame region are emitted out from the frame region of the second substrate. The above liquid crystal grating enables a seam of a spliced screen to have a certain display brightness, thereby improving the display effect of the spliced screen.

    Abstract: The present disclosure relates to an information prompting bracelet and an information prompting system. The information prompting bracelet includes: a flexible substrate, a connecting portion, control portions, pressure levers and an elastic deformation portion. When the control portions receive promoting information, they will control the pressure levers to move towards the side facing the flexible substrate. With the movement of the pressure levers, the elastic deformation portion will be squeezed towards the middle region, so that the distance between the inner surface of the elastic deformation portion at the middle region and the inside of the flexible substrate after squeezing will be larger than the distance between the inner surfaces of the pressure levers and the inside of the flexible substrate when in an initial position. In this way, this will bring the wearer a sense of pressure to notify the wearer that there is a prompting signal needing to be received.
