Dynamic image control device with homopolar black frame insertion signals

Abstract

The invention relates to a dynamic image control device with homopolar black frame insertion signals, comprising a time-sequence control unit, a data access unit, a buffer unit, a cache, a storage unit, a data output unit and a driving signal unit. The time-sequence control unit is used for controlling the time-sequence; the data access unit is connected with the time-sequence control unit for accessing data; the buffer unit is connected with the data access unit for temporarily storing the data; the cache is connected with the time-sequence control unit for temporarily storing time-sequence data; the storage unit is connected with the cache for storing set time-sequence data; the data output unit is connected with the time-sequence control unit and the data access unit for outputting the data; and the driving signal unit is connected with the time-sequence control unit and the cache to output related driving signals. Therefore, the black frame insertion signals can be in line with the 1+2 line inversion display way, and the polarity showed by a liquid crystal can be consistent during the data display and the black frame insertion display, thereby avoiding affecting the image response time due to different response speeds.

Description

technical field [0001] The present invention relates to a dynamic image control device with same-polarity black insertion signal, especially a dynamic image control device that can make the black insertion signal comply with 1+2 line inversion display mode. Background technique [0002] Generally speaking, blank insertion is often used to improve the animation quality of the panel, using the presentation of black data to eliminate the integration effect of the human eye on the image, and then make the animation afterimage of the LCD TV screen (LCD TV) Disappear to increase animation quality; but the current black insertion technology uses the method of writing the same polarity once, which cannot match the polarity when displayed, which may cause inconsistent response speeds of adjacent liquid crystals, resulting in inconsistent color display The right situation happens. [0003] The general black insertion technology is to continuously open several gate signal lines (Gate ...

Problems solved by technology

[0004] This method is relatively simple in timing controller (Timing controller; Tcon) design, but it may not be suitable for horizontal polarity, because this method turns on four gate signal lines at a time, and writes the same polarity at the same time. The signal is different from the way in which the 1+2 lines of the original display data are written in different polarities, which may affect the response speed of the liquid crystal.

Therefore, the general public cannot meet the needs of users in actual use
