Field of the Invention

The present disclosure relates to a display field, and more particularly to an adjusting method of displaying images.


BACKGROUND OF THE INVENTION

In the display field, a cathode ray tube (CRT) has been gradually replaced by a flat display device like a liquid crystal display (LCD) or an organic light-emitting diode (OLED). The LCD has advantages of thin frame, low power, and low radiation, and has been widely used.


Most LCDs in the market are the type of backlight-LCDs that include LCD panels and backlight modules. The LCD panel includes a color filter (CF) substrate, a thin film transistor (TFT) substrate, a liquid crystal (LC) between the CF substrate and the TFT substrate, and a sealant. The operating principle of the LCD panel is that the liquid crystal molecules are disposed between two glasses being parallel with each other. A plurality of vertical and horizontal tiny wires are within two glass substrates. Voltages are applied to control the liquid crystal molecule to change orientation to refract the light of the backlight module to produce images.


The OLED usually includes: a substrate, an anode disposed on the substrate, a hole inject layer (HIL) disposed on the anode, a light emitting layer disposed on the HIL, an electron transport layer (ETL) disposed on the light emitting layer, an electron inject layer (EIL) disposed on the ETL, and a cathode disposed on the EIL. The operating principle of the LCD panel is that by applying the electric field to drive the semiconductor material and the organic light emitting layer, the charger carrier is injected in the composite material to emit light. Specifically, the OLED usually utilizes an ITO electrode and a metal electrode as the anode and the cathode, respectively. By applying a certain voltage, electrons and holes are injected into the ETL and the HTL, respectively. The electrons and the holes are transported to the light emitting layer via the ETL and the HTL, respectively, to form activators to activate light emitting molecules. The light emitting molecules emit the visible light by radiation relaxation.


With development of the displaying technology, large scale display panels are widely used by the customers. Due that the large scale display panels have large dimension, the consistence within the panel is poor, resulting in that the display panel has various mura and line defect. The solution to solve the mura of the display panel is demura. However, due of the precision, the issue about defects of vertical lines including a vertical poor-line and a vertical bright-line cannot be solved by the demura apparatus. The defect of the vertical poor-line is that a brightness of the pixels of one row is lower than a brightness of the pixels of two adjacent row, resulting in the vertical poor-line. The defect of the vertical bright-line is that a brightness of the pixels of one row is higher than a brightness of the pixels of two adjacent row, resulting in the vertical bright-line. The defect of the vertical lines highly affects the display quality.
