Disclosed are a driving method and a driving device for improving a contrast of an OLED image. The driving method includes steps of dividing an OLED display panel into a plurality of partitions, calculating an average pixel level of one frame of image to be displayed corresponding to each partition, determining, based on the average pixel level, a preset value of a discharge reference voltage, and regulating the discharge reference voltage applied to pixel driving circuits in the partition to the preset value. The driving method can significantly improve the contrast of the OLED image during display.

Driving method and driving device for improving contrast of OLED image

The present invention discloses a display device, comprising a display panel, a data driving circuit, and a scan driving circuit, the data driving circuit being disposed on a side of the display panel in a first direction, the scan driving circuit being disposed on a side of the display panel in a second direction, the first direction being perpendicular to the second direction; both the data driving circuit and the scan driving circuit are connected to the display panel. The present invention can reduce a width of a non-display region of the display device under a premise of improving a display quality.

The present disclosure relates to the field of liquid crystal display, and particularly to a glass substrate for a display. The glass substrate is treated through a vapor deposition apparatus, and includes an optical compensation film. The optical compensation film has a relatively higher transmittance in a compensation area than in other areas, and the shape and position of the compensation area are configured to be consistent with a non-uniform heated area caused by the vapor deposition apparatus on the glass substrate. The present disclosure further relates to a corresponding method for manufacturing the glass substrate. According to the present disclosure, the defects of the glass substrate can be accurately overcome and the mura phenomenon of the display panel can be reduced.

Glass substrate for display and manufacturing method thereof

The present disclosure discloses a system of self-adaptively adjusting Multi-area common voltage, comprising a plurality of photosensitive devices, for sensing luminous quantity from the different areas so as to obtain and transmit flicker values corresponding to the different areas; a multiplexing element, connected with the plurality of photosensitive devices; a calculation and comparison unit, for continuously receiving the flicker values which are sensed by the plurality of photosensitive devices in a time sequence, calculating actual display condition, and comparing the actual display condition with an optimal display condition; and an common voltage adjusting and outputting unit, connected with the calculation and comparison unit, for adjusting the value of the current output common voltage if the optimal display condition is not met and remaining the value of the current output common voltage unchanged if the optimal display condition is met. The present disclosure can achieve automatically adjustment of the common voltage and thus increase the productivity.
