Abstract: A display device includes display panel component and a signal controller. The display panel components include a plurality of pixels arranged in a matrix, at least two data drivers, and data lines connecting to each of the data driver, and the pixels connect to the corresponding data line. The signal controller connects to the two data drivers to obtain two data voltages from data lines connecting to two adjacent data drivers when the pixels display mono-color images having the same grayscale. The signal controller adjusts gamma codes of the two adjacent data drivers in accordance with the obtained the data voltages until the data voltages of the data lines respectively connected to the two adjacent data drivers are the same. In view of the above, the screen split issue caused by adopting at least two data driver may be eliminated so as to enhance the display performance.

Abstract: The invention discloses a transparent OLED display and manufacturing method thereof. The present invention provides a manufacturing method of transparent OLED display, by preparing the cathode and the anode on two different substrates to effectively avoid the destruction of the light-emitting layer made of the organic light-emitting material caused by sputtering the anode at the top of OLED to improve yield rate. The use of the transparent conductive metal oxide to manufacture the cathode and the anode of the OLED display provides an effective solution to the manufacturing of transparent OLED display which requires high conductivity and high transparency for the electrode material. In addition, the two substrates can be manufactured the same time and then pressed to attach to achieve high manufacturing efficiency. The OLED display provided by the present invention is easy to manufacture and provides good performance.
