Embodiment Construction

[0092] First, please refer to image 3 , which is a circuit diagram of a preferred embodiment of the present invention. As shown in the figure, the display of the present invention includes a plurality of unit pixels 10, a gate driving circuit 20, a data driving circuit 30, a timing controller 40 and a common voltage source V COM . The gate drive circuit 20 is coupled to a plurality of gate lines 60, and the data drive circuit 30 is coupled to a plurality of data lines 70, the gate lines 60 are arranged in columns, and the data lines 70 are arranged in rows and connected to the gates. The polar lines 60 cross each other to form the unit pixel 10 , and the unit pixel 10 forms a frame. Each unit pixel 10 includes a switch component 12 , a storage capacitor 14 and a liquid crystal capacitor 16 . The switch component 12 is used to control the display of the unit pixel 10 . The switch component 12 can be a transistor. The storage capacitor 14 and the liquid crystal capacitor 16 ...

Abstract

A driving method of display includes sending multiple grid signal to drive switch component, sending multiple data signal for providing pixel voltage to unit pixel to generate voltage difference, controlling voltage difference sum of each unit pixel at group time to be zero, displaying at least one group pixel in each driving unit time and containing multiple brightness grey level value in group pixel, making said brightness grey level value be consistency to an expected value for not only increasing visual angle of display but also avoiding ghost on display.

Description

technical field [0001] The invention relates to a driving method, in particular to a display driving method and a photoelectric device. Background technique [0002] With the advancement of current display research and development technology, various display manufacturers have successively launched various displays, such as Liquid Crystal Display (LCD), Plasma Display Panel (PDP) and Organic Light Emitting Diode (Organic Light Emitting Diode, OLED) displays, etc. Among current displays, whether it is Twisted Nematic LCD (TN-LCD), Multi-Domain Vertical Alignment LCD (MVA-LCD) or horizontal electric field switching LCD (In-Plane Switch LCD, IPS -LCD), the user will have color distortion when watching the picture at a large viewing angle. The color will be different from the color viewed at the front viewing angle, which will cause the user to watch the color screen with normal brightness only within a certain viewing angle. To the picture of distorted color, this makes the ...
