TWI225562B - Liquid crystal display with function of digital photo frame - Google Patents

Abstract

There is provided a liquid crystal display with function of digital photo frame, which includes an image decoder, a control device, a scaler and a liquid crystal panel. A memory card is electrically connected to the image decoder via being inserted into the memory card socket of the liquid crystal display. After the memory card is inserted into the memory card socket, the compressed image data stored in the memory card can be fed into the image decoder for being decompressed into digital image signals. Next, a transmission circuit arranged in the image decoder transmits the digital image signals to a digital image processor in the scaler via a transmission interface. The scaler thus generates display signals required by the liquid crystal panel based on various parameters in the digital image signals, thereby enabling the liquid crystal panel to display the digital picture in the memory card based on the display signals. On the other hand, the image decoder is able to communicate with the scaler via control signals, so as to complete transmission of digital image signals, wherein the control signals can be generated by a control device, or the required control signals can be outputted by the scaler itself.

Description

1225562 V. Description of the invention (1) [Invention belongs to the present invention with digital phase [Previous technology] With the help of the branch, it is necessary to cut costs. Basic needs have also become a leisure result. Although the excellent footsteps of electricity breaks out and pushes the lighter look's momentum. Take pens and desktop notebook computers to listen to music, although pens play a mainstream role in mobility. The use of non-brain screen technology field] is about _ a kind of LCD with frame function] The technology industry is booming At present, personal computers ’multimedia resources. For many home entertainment centers, the brain has been brought to people but has not slowed down; smart, convenient and high-competitive notebook computers have the biggest dividing function of the brain. Computers are common among home users, and video and audio media are often common. Therefore, the way of browsing, the LCD display, not only can be expected, it shows that the consumer market is very specialized in performance. Research desktop type (referring to the probabilities that have not been made, the table body should be displayed digitally and gradually, and especially the relationship between them and the personal computer also meets the most logical or 3D computer games such as word processing and Internet access. And other applications, the room with a personal computer has become a must-have product for technology to enter life.

1225562 V. Description of the invention (2) It means that the memory card is inserted into the personal watch; or the digital camera is connected with the data, and the photos are discounted. Therefore, for the same operation as in the past. [Content of the invention] In view of this function, the LCD display directly benefits the display according to the present invention. After installing the digital phase element and the proportional memory card slot, the encoder is stored. Each of the image signals in the electrical proportional device in the decompressor makes the LCD panel on the one hand. When digital images are taken, most people are accustomed to using a card reader on a computer that stores the photos and then using the viewing software in the computer to view them. Data transmission cable (such as USB standard or IEEE 1 394 standard). No matter what kind of behavior is adopted, the computer needs to be turned on. But in this way, the convenience improves the convenience of operation. It is necessary to develop different ways to make technology more humane. 'The purpose of the indicator (LCD for liquid crystal display of the present invention is described briefly, such as the liquid function of the frame function, the liquid crystal surface and the image decoding are reduced to a digital shadow path in a memory card, and the data display signal can be generated using the parameters of the digital image. The purpose of the decoder and the comparison is to monitor: the display number of the display is proposed: the crystal display board, the electronic image transmission transmission device to display an example of a display memory serial miniature. Interface, than the crystal surface is not stored In order to provide a digital photo frame, you can take photos without the computer booting. LCD with digital photo frame function including video card is borrowed. Recording data Then, the digital example device board can be borrowed in the middle of the memory card The decoding can be fed by the LCD memory card, which can be fed into the image signal, and the required display digits can be sent by the controller and the control display to the memory card. The image decoding image decoding number is transmitted to the digital image signal and photo. Another 5 Tiger each other

Description of the invention (3) Communication is completed to complete the transmission of digital image signals; it utilizes control elements; i ^ Y controls 4 可 号 可 号. The control information required by the device or output by the proportional device itself understands the purpose, characteristics, and advantages of umii. It can be more easily understood, and the preferred embodiment is given.泮 Detailed description [Embodiment] The basic principle of a digital camera is to use a light sensing element or CMOS to capture the scene under the lens, and then through complicated calculation procedures such as signal conversion and 1 compress, convert the lens = to Compress image data and save it to a memory card. In other words, the film is stored in the memory card in the form of compressed image data. Depending on the compression ratio (comm rate), the digital phase also has different resolutions (resolution)- The higher the compression ratio, the worse the resolution. When viewing digital photos, it is necessary to decompress the compressed image & data in the memory card. The decompression can be achieved by using a video decoder (such as a J PEG decoder). After the compressed image data is decompressed into a digital image signal, the liquid crystal display can display digital photos as long as it is displayed according to the extracted digital image signal. The main point of the present invention is that digital photos can be played directly by using a liquid crystal display to improve the convenience of photo browsing. Please refer to FIG. 1 'which shows a first embodiment of the present invention.
