Background technology
Due to liquid crystal display have that external form is thin, lightweight, power consumption is low, radiation is low and can with the advantage such as semiconductor process techniques is compatible, therefore it is little by little widely used.
Under different Liquid Crystal Molecules Alignment states, optical characteristics during light penetration liquid crystal layer is also different, changes the ordered state of liquid crystal molecule by applying electric field, to control the amount of penetrating of light, and then produces the output light of varying strength.Namely liquid crystal display utilizes this characteristic to produce the redness of varying strength, green and blue light, to show image, and the brightness of the electric field that is applied in of the shades of colour composition of its each pixel and generation can represent by a pixel value, such as: (R, G, B) redness, green and blue component is wherein represented respectively, (0,0,0) representative complete dark (i.e. black), and (255,255,255) represent Quan Liang (i.e. white).
Because liquid crystal molecule first must change ordered state, could change and export the intensity of light, reaction velocity is comparatively slow, and when a pixel will convert a target pixel value to from a starting pixel value, having to pass through a period of time just can reach this target pixel value.Therefore, when user uses liquid crystal display to show high speed dynamic menu (such as: viewing DVD film or play computer game), display quality bad (such as: picture has ghost or discontinuous) can be felt.
Generally use the mode of too drastic (Overdrive) to reduce the liquid crystal reaction time.Such as: when a pixel will from a starting pixel value (40,40,40) target pixel value (80 is converted to, 80,80), time, liquid crystal is applied and a too drastic pixel value (120,120,120) corresponding electric field, reaches this target pixel value to make this pixel within the time of specifying; And when a pixel will from a starting pixel value (120,120,120) target pixel value (80 is converted to, 80,80), time, liquid crystal is applied and a too drastic pixel value (40,40,40) corresponding electric field, reaches this target pixel value to make this pixel within the time of specifying.
In order to obtain this too drastic pixel value efficiently, normally first setting up a too drastic table (OverdriveTable), then inquiring about this too drastic table according to this starting pixel value and this target pixel value, to export this too drastic pixel value.
But for each liquid crystal display, its too drastic table is fixing, cannot, by user from Row sum-equal matrix, the liquid crystal reaction time of its entirety can only be made to reach a fixed value preset.And the display effect that each user likes is not identical.When user feels have other spinoff to occur, or the liquid crystal reaction time is still fast not, when making display quality bad, can not carry out adjusting to reach satisfied state, cause user's adjustment finite elastic in use.
Moreover, the manufacturer of liquid crystal display is when producing, first can produce an original too drastic table according to the average characteristics of its product, this original too drastic table is finely tuned again for each product, to reach identical display effect, this makes manufacturer the expensive time must do the work of finely tuning, and then significantly increases production cost.
