    Abstract: A pixel compensation method, pixel compensation apparatus and display device are provided. In the blanking section of (2n−1)th display frame, the detection line corresponding to the first sub-pixel column of the same color sub-pixels in the nth row is charged with an additional detection voltage, such that the detected voltage on this detection line is the sum of the detection voltage and a coupling voltage. The detection line corresponding to the second sub-pixel column of the same color sub-pixels is not charged with the additional detection voltage, such that the detected voltage on this detection line is the coupling voltage. The detection voltage corresponding to the first sub-pixel column is obtained according to the voltage on the detection line corresponding to each of the same color sub-pixels. Similarly, in the blanking section of (2n)th display frame, the detection voltage corresponding to the second sub-pixel column may be obtained.

    Abstract: Disclosed are a method for color complementation on a white organic light emitting diode (WOLED) display device, and a display device. The method comprises: (a) acquiring respective first chromaticity coordinates of each of red (R), green (G), blue (B), and white (W) sub-pixel units for a brightness outputted by the WOLED display device; (b) calculating a first complementary color ratio among the R, G, B, and W sub-pixel units; (c) determining a desired brightness of the W sub-pixel unit, and obtaining respective first complementary color brightnesses of each of the R, G, B, and W sub-pixel units, and in turn determining respective second chromaticity coordinates of each of the R, G, B, and W sub-pixel units corresponding to the respective first complementary color brightness of each of the R, G, B, W sub-pixel units; and (d) implementing in iterations steps (a), (b) and (c), so as to obtain a second complementary color ratio among the R, G, B, W sub-pixel units corresponding to the desired brightness of the W sub-pixel unit. Color complementation of the WOLED display device is carried out depending on the second complementary color ratio among the R, G, B, and W sub-pixel units when the brightness outputted by the WOLED display device reaches the desired brightness of W sub-pixel unit.

    Abstract: A pixel circuit is provided which includes a data writing module, a drive module, a control module and an electrochromic device. The data writing module provides a data signal to the control terminal of the drive module under the control of a first control signal. The drive module drives the electrochromic device for color development or color fading according to a power supply voltage signal under the control of the data signal. The control module controls the conduction between the drive module and the electrochromic device on the basis of a second control signal, and the control module controls the conduction so that the conduction is realized later than the change in the power supply voltage signal. The pixel circuit effectively removes interference of the power supply voltage signal, avoids display fluctuations caused by the change in the power supply voltage signal, and further improves the display effect.

    Abstract: The present invention relates to a heat sinking pad and a printed circuit board. The surface of the heat sinking pad on which electronic components are placed comprises a solder loading area and a solder non-loading area, wherein the solder loading area is used for being coated with solder; and the solder non-loading area comprises heat collection passages for collecting heat on the heat sinking pad and heat dissipation passages communicated with the heat collection passages. Openings of the heat dissipation passages are positioned at edges of the heat sinking pad so as to discharge the heat collected by the heat collection passages to the outside of the heat sinking pad. The heat dissipation to the edges of the heat sinking pad along the heat collection passages and the heat dissipation passages is faster than along the solder loading area, so the heat sinking pad has higher heat dissipation speed.
