The display device provided in the application detects the pixel voltages of the first to-be-detected sub-pixel and the second to-be-detected sub-pixel electrically connected to the same data line through the detection module. The first to-be-detected sub-pixel is a sub-pixel in which the first transistor electrically connected to the data line is turned on to write the data signal, and the second to-be-detected sub-pixel is a sub-pixel in which the second transistor electrically connected to the data line is turned on to write the data signal. The pixel voltage of the first to-be-detected sub-pixel is related to the turn-on degree of the first transistor, and the pixel voltage of the second to-be-detected sub-pixel is related to the turn-on degree of the second transistor. The compensation module provides a compensation signal to the clock signal control module according to the detection result of the detection module. The voltage value of the first clock signal for controlling the turn-on of the first transistor or the voltage value of the second clock signal for controlling the turn-on of the second transistor is compensated by the clock signal control module, so that the luminance of the sub-pixels on the same data line is consistent, and the brightness and darkness uniformity of the display picture is improved.

The invention relates to the technical field of light guide elements, in particular to a horse race lighting effect light guide plate which comprises an injection molding light guide plate, a reflecting film covering and attached to the bottom face of the injection molding light guide plate and a shading film partially covering and attached to the top face of the injection molding light guide plate. The area, located between the periphery of the injection molding light guide plate and the periphery of the shading film, of the injection molding light guide plate is a light emitting area, the outer side face of the injection molding light guide plate is obliquely arranged towards the center direction of the injection molding light guide plate from bottom to top, and the outer side face of the injection molding light guide plate and the top face of the injection molding light guide plate are arranged in a fillet mode. Light is smoothly transited to the corner between the outer side face of the injection molding light guide plate and the bottom face of the injection molding light guide plate and then is dispersed through the reflecting film, so that the phenomenon that a local area of a light emitting area is exploded and brightened due to the fact that a horse race luminous efficiency light source is too close to the light emitting area is effectively improved, the light emitting brightness of the light emitting area is balanced, and the light emitting effect is improved.

The invention discloses a pixel circuit, a driving method thereof and a display panel. The pixel circuit comprises a driving module, a threshold compensation module, a storage module, a light-emitting control module and a light-emitting module, the light-emitting module, the driving module and the light-emitting control module are sequentially connected in series between the first power supply and the second power supply; the storage module is connected with the first end of the driving module; the threshold compensation module is connected between the first power supply and the second end of the driving module, and the threshold compensation module is used for charging the storage module based on the first power supply in a compensation stage so as to transmit the threshold voltage of the driving module to the first end of the driving module. According to the technical scheme, the display performance of the display panel is improved.
