| Abstract: | TFF-LCD screen is widely used in vehicle interactive system,which is mainly used to display navigation maps,vehicle status information and so on.This paper introduced the working principle of TFT-LCD screen and the causes of its hardware,and software display defect has be analyzed.A display optimization algorithm is proposed in this paper.The work flow of discrete cosine transform,wavelet domain transformation and two-dimensional character division of the optimization algorithm are introduced in detail.Theoretical simulation results show that the optimization algorithm has better saturation and contrast index,and the experimental results show that the optimization algorithm is better enough to achieve a better visual experience. |
