Embodiment

[0029] like figure 2 As shown, the packaging structure adopts a CSP structure, including a resin lens and a filter, and a protective glass for the photosensitive chip is provided. The resin lens, the filter 204 and the protective glass 205 for the photosensitive chip are arranged in sequence. The resin lens adopts a three-piece resin lens structure. The first resin lens 201 adopts a double-convex structure, the second resin lens 202 adopts a concave-convex structure, and the third resin lens 203 adopts a convex-concave structure. The third resin lens has an optimized inflection point at a position 0.7 above the center line of the lens. The 0.7 position is to divide the whole lens into 10 parts on average, and the 0.7 position is the seventh position above the center line of the lens; the first resin lens is made of resin APL5514, the second resin lens is made of resin OKP4, and the third resin lens APL5514 material is used; the aperture stop is placed on the object side of th...

Abstract

The invention relates to a three-lens five-mega-pixel front camera of a mobile phone. The three-lens five-mega-pixel front camera comprises resin lenses and an optical filter and is provided with light-sensitive chip protection glass. The resin lenses, the optical filter and the light-sensitive chip protection glass are sequentially arranged. The number of the resin lens is three. The first resin lens is of a biconvex structure, the second resin lens is of a concave-convex structure, and the third resin lens is of a convex-concave structure. The first resin lens is made of resin APL5514, the second resin lens is made of resin OKP4, and the third resin lens is made of APL5514 materials. An aperture diaphragm is placed on the face of the object space of the first lens. According to the three-lens five-mega-pixel front camera of the mobile phone, the chromatic aberration problem produced by an optical system can be well solved, the overall length is greatly reduced, a large number of costs are saved, many changes can be brought to system optimization, and advanced chromatic aberration caused by the large field angle can be better lowered.

Description

technical field [0001] The invention relates to a mobile phone front camera lens, in particular to a three-piece 5 million pixel mobile phone front camera lens. Background technique [0002] At present, with the rapid development of mobile terminal 3G / 4G services, the mobile phone industry has developed rapidly. As a very important part of the mobile phone industry, the camera function of mobile phones has driven the progress of the entire mobile phone lens industry. Due to the current high-order aspheric processing technology, the accuracy has been greatly improved, and the pixel size of the image sensor has also dropped below 1.1 microns, coupled with the emergence of new materials, these technological advances have promoted the manufacturing level of mobile phone lenses of continuous improvement. Therefore, mobile phone lenses with mid-to-low-end pixels are gradually being replaced by high-end lenses. The current development trend is: under the premise of higher and hig...
