Abstract: The present application relates to a pixel arrangement structure, including first sub-pixels, second sub-pixels, third sub-pixels, and fourth sub-pixels. Centers of two of the first sub-pixels arranged opposite to each other and centers of two of the second sub-pixels arranged opposite to each other are taken as vertices and are connected to form a virtual quadrilateral. The virtual quadrilateral includes two equal sides arranged opposite to each other, a short side and a long side arranged opposite to each other and connected to vertices of the equal sides. The short side of the virtual quadrilateral is not parallel to the long side of the virtual quadrilateral. One of the third sub-pixels or one of the fourth sub-pixels is arranged in the virtual quadrilateral, and the third sub-pixel and the fourth sub-pixel emits light in a same color.

Abstract: The application discloses an auxiliary method and device for one time programmable (OTP) adjustment of a display panel. The auxiliary method includes: crimping and conducting a flexible circuit board to a display panel bonded with a chip by means of pre-bonding, to lead a crimping impedance by the flexible circuit board; detecting the crimping impedance led by the flexible circuit board; and screening a detected crimping impedance value to determine whether the OTP adjustment is enabled, wherein when the crimping impedance value meets a preset condition, the OTP adjustment is enabled, and when the crimping impedance value does not meet the preset condition, the OTP adjustment is disabled.

Abstract: An evaporation mask, an organic light-emitting diode (OLED) panel and system, and an evaporation monitoring method. The evaporation mask includes a first functional region and a first peripheral region disposed outside of the first functional region. The first functional region has a first opening for forming a functional layer by evaporation, and the first peripheral region has a second opening for monitoring an evaporation effect of the first opening. A monitoring structure can be formed on an observation layer of the OLED panel by evaporation through the second opening of the evaporation mask, and the evaporation effect of the first opening of the evaporation mask can be monitored via the monitoring structure, so that the evaporation effect can be monitored in time to achieve real-time on-line monitoring.

Abstract: A pixel structure, an Organic Light-Emitting Diode (OLED) display device, and a driving method. The pixel structure includes a number of pixel units arranged in a matrix form. Each pixel unit includes two pixel subunits adjacently arranged along a first direction and includes three sub-pixels having different colors. The two pixel subunits constitute two pixels adjacently arranged along the second direction. A distance between centers of two sub-pixels having a same color in two pixels not adjacent in three consecutive pixels in the second direction is 2 or 2N/(N+1) times of a distance between the centers of two sub-pixels having the same color in two adjacent pixels in the first direction. N is an integer greater than or equal to 1.

Abstract: A display panel includes two first sub-pixels and two second sub-pixels which are connected as a first virtual quadrilateral. Each of the two first sub-pixels includes a first subordinate sub-pixel and a second subordinate sub-pixel facing to each other and spaced apart from each other. One of two first vertices of the first virtual quadrilateral being located between the first subordinate sub-pixel and the second subordinate sub-pixel of one of the two first sub-pixels, the other one of the two first vertices being located between the first subordinate sub-pixel and the second subordinate sub-pixel of another one of the two first sub-pixels. Two second sub-pixels are respectively located at two second vertices of the first virtual quadrilateral. The two first vertices and the two second vertices are alternately arranged and spaced apart from each other. The display panel includes a third sub-pixel located within the first virtual quadrilateral.
