Embodiment Construction

[0084] FIG. 2A is a block diagram of the LCOS display 200. The LCOS display 200 includes a PCB 210, an interface module 220, a first silicon chip 230, and a flat cable 270. The interface module 220 is located on the PCB 210 and is used to receive audiovisual signals. The first silicon chip 230 includes a display area 240, a processing area 250, and a metal layer 310 (illustrated in FIG. 2B). The display area 240 includes a pixel array 241 formed on the first silicon chip 230. The processing area 250 includes a processing unit 260 formed on the first silicon chip 230. The metal layer 310 is formed on the first silicon chip 230 to electrically connect the display area 240 and the processing area 250. The flat cable 270 electrically connects the interface module 220 and the processing unit 260. The flat cable 270 may be a flexible flat cable (FFC) or an FPC cable, but it is not used to limit the present invention.

[0085] For example, the interface module 220 may include a serial co...

Abstract

The present invention provides a LCOS display. The display comprises a first PCB, an interface module, a first silicon chip, and a flat cable. The interface module is disposed on the first PCB and used to receive an audio and video signal. The first silicon chip comprises a display area, a processing area, and a metal layer. The display area comprises a pixel array in a LCOS panel formed on the first silicon chip. The processing area comprises a processing unit formed on the first silicon chip. The metal layer is formed on the first silicon chip for electrically connecting the display area with the processing area. The flat cable is used to electrically connect the interface module with the processing unit.

Description

Technical field [0001] The invention relates to a liquid crystal display (LCD), and more particularly to a liquid crystal on silicon (LCOS) display and its packaging. Background technique [0002] Figure 1A The block diagram of the LCOS display 100 is shown. The LCOS display 100 includes an LCOS panel 103, an Audio and Video (A / V) system board 102, and an input / output (I / O) connection board 101. The I / O connection board 101 is electrically connected to the audio-visual system board 102 via a signal line 104, and the audio-visual system board 102 is electrically connected to the LCOS panel 103 via a flexible printed circuit cable (FPC cable) 105. The I / O connection board 101 is used to receive video and audio signals. The audio-visual system board 102 is used to perform audio-visual processing of audio-visual signals. The LCOS panel 103 is used to display the processed video and audio signals. [0003] FIG. 1B is a detailed block diagram of the LCOS display 100. The I / O board 101...
