Problems solved by technology

[0005] In order to realize the compensation for the threshold voltage Vth shift of the T1 drive transistor, it is necessary to give the gate of the T1 drive transistor two different data signals Vdata (Vdata1, Vdata2). The frequency of lvds) is low. To satisfy the compensation function of the Vth of the T1 drive transistor, it is necessary to reduce the frame rate (frame rate) and then increase the Mini clk (within the specification of the drive chip) to compensate. This method Can not meet the needs of mass production

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a data-driven chip architecture and a timing controller architecture suitable for AMOLED compensation. Background technique [0002] Organic light-emitting diode (OLED) display devices have many advantages such as self-luminescence, low driving voltage, high luminous efficiency, short response time, and wide operating temperature range, and are recognized by the industry as the display device with the most development potential. [0003] The installation and driving methods of OLED display devices can be divided into two categories: passive matrix OLED (PMOLED) and active matrix OLED (AMOLED). Among them, AMOLED has sub-pixels arranged in an array, which belongs to the active display type. High, usually used for high-definition large-size display devices. [0004] see Figures 1 to 3 , figure 1 It is a schematic diagram of an existing OLED pixel structure, which is a 3T1...
