艾诺V6000HDS拆解
神秘高清芯片揭秘艾诺V6000HDS拆解!艾诺推出V6000HD系列高清MP4产品后，获得极大的市场反映，国内MP4市场全面进入高清时代。
而近期上市的V6000HDS更是在性能上进一步提高，实现了768P高清解码，同时具备更优秀的电源管理，据之前的宣传和内部人员透露，V6000HDS采用的解码芯片和之前的V6000HDM、V6000HDA、V6000HDG 都不同，究竟是何方神圣呢？我们带着各种疑问，决定将V6000HDS进行拆机，来一探究竟。
拆机行动正式开始，首先我们先得找个下手的地方，经过仔细观察，我们发现艾诺V6000HDS的正反两面都非常简洁，机身四周设计了案件和接口，但是并没有发现明显的螺丝，用指甲切入机身上下两侧的缝隙可以发现艾诺V6000HDS的机身结合得非常紧密，看来艾诺的工程师在外观设计方面还是下了不少心思。
经过仔细研究，我们发现机身两侧的网状的喇叭发音孔存在小小的破绽，我们用细尖刀撬开，果然发现其左右两端各设计了一个螺丝，中间则是长条形的发音孔。
网状的发音孔可以有效防止灰尘进入喇叭内部，从而导致杂音存在，同时也使得整机更为美观。
我们先把左右两侧共4颗粒螺丝卸下。
卸下螺丝后，我们用指甲掰开正反两面的外壳，在拆解的过程中，我们可以发现艾诺V6000HDS的外壳采用卡扣（咬合）设计，卡扣的数目较多，因此能够保证机子的密闭性良好。
将机身四周的卡扣分离后，我们便可以将机身的正面面板拆开，在拆解的过程中，我们还发现艾诺V6000HDS的外壳塑料韧性不错，不会出现拆解一次就断裂的情况，说明机子的整体质量还是非常可靠的。
将卡扣全部剥离后，我们就可以将整块前面板拆下。
可以看到机子的内部被5寸的屏幕覆盖，周围几乎没有空间。
而且屏幕的四周都设计了金属框架，有效地加强了屏幕的抗撞击性能，一定程度上减少机子意外跌落而导致屏幕破裂的几率。
屏幕和底板之间没有设置固定的螺丝，基本靠机身面板背面的塑料位卡稳。

Handling Precautions8.1 Mounting methodThe LCD panel of Daxian LCD module consists of two thin glass plates with polarizes which easily be damaged. And since the module in so constructed as to be fixed by utilizing fitting holes in the printed circuit board.Extreme care should be needed when handling the LCD modules.8.2 Caution of LCD handling and cleaningWhen cleaning the display surface, Use soft cloth with solvent[recommended below] and wipe lightlyIsopropyl alcoholEthyl alcoholDo not wipe the display surface with dry or hard materials that will damage the polarizer surface.Do not use the following solvent:WaterAromaticsDo not wipe ITO pad area with the dry or hard materials that will damage the ITO patternsDo not use the following solvent on the pad or prevent it from being contaminated:Soldering fluxChlorine (Cl) , Salfur (S)If goods were sent without being sili8con coated on the pad, ITO patterns could be damaged due to the corrosion as time goes on.If ITO corrosion happen by miss-handling or using some materials such as Chlorine (CI), Salfur (S) from customer, Responsibility is on customer.8.3 Caution against static chargeThe LCD module use C-MOS LSI drivers, so we recommended that you: Connect any unused input terminal to Vdd or Vss, do not input any signals before power is turned on, and ground your body, work/assembly areas, assembly equipment to protect against static electricity.8.4 packingModule employ LCD elements and must be treated as such.Avoid intense shock and falls from a height.To prevent modules from degradation, do not operate or store them exposed direct to sunshine or high temperature/humidity8.5 Caution for operationIt is an indispensable condition to drive LCD’s within the specified voltage limit since the higher voltage then the limit cause the shorter LCD life.An electrochemical reaction due to direct current causes LCD’s undesirable deterioration, so that the use of direct current drive should be avoided.Response time will be extremely delayed at lower temperature then the operating temperature range and on the other hand at higher temperature LCD’s how dark color in them. However those phenomena do not mean malfunction or out of order with LCD’s, which will come back in the specified operation temperature.If the display area is pushed hard during operation, some font will be abnormally displayed but it resumes normal condition after turning off once.A slight dew depositing on terminals is a cause for electro-chemical reactionresulting in terminal open circuit.Usage under the maximum operating temperature, 50%Rh or less is required.8.6 storageIn the case of storing for a long period of time for instance, for years for the purpose or replacement use, the following ways are recommended.Storage in a polyethylene bag with the opening sealed so as not to enter fresh air outside in it . And with no desiccant.Placing in a dark place where neither exposure to direct sunlight nor light’s keeping the storage temperature range.Storing with no touch on polarizer surface by the anything else.[It is recommended to store them as they have been contained in the inner container at the time of delivery from us8.7 SafetyIt is recommendable to crash damaged or unnecessary LCD’s into pieces andwash off liquid crystal by either of solvents such as acetone and ethanol, which should be burned up later.When any liquid leaked out of a damaged glass cell comes in contact with your hands, please wash it off well with soap and water9. Precaution for use9.1A limit sample should be provided by the both parties on an occasion when the both parties agreed its necessity. Judgment by a limit sample shall take effect after the limit sample has been established and confirmed by the both parties.9.2On the following occasions, the handing of problem should be decided through discussion and agreement between responsible of the both parties.When a question is arisen in this specificationWhen a new problem is arisen which is not specified in this specifications When an inspection specifications change or operating condition change in customer is reported to Daxian , and some problem is arisen in this specification due to the changeWhen a new problem is arisen at the customer’s operating set for sample evaluation in the customer site.10.

Handling Precautions8.1 Mounting methodThe LCD panel of Daxian LCD module consists of two thin glass plates with polarizes which easily be damaged. And since the module in so constructed as to be fixed by utilizing fitting holes in the printed circuit board.Extreme care should be needed when handling the LCD modules.8.2 Caution of LCD handling and cleaningWhen cleaning the display surface, Use soft cloth with solvent[recommended below] and wipe lightlyIsopropyl alcoholEthyl alcoholDo not wipe the display surface with dry or hard materials that will damage the polarizer surface.Do not use the following solvent:WaterAromaticsDo not wipe ITO pad area with the dry or hard materials that will damage the ITO patternsDo not use the following solvent on the pad or prevent it from being contaminated:Soldering fluxChlorine (Cl) , Salfur (S)If goods were sent without being sili8con coated on the pad, ITO patterns could be damaged due to the corrosion as time goes on.If ITO corrosion happen by miss-handling or using some materials such as Chlorine (CI), Salfur (S) from customer, Responsibility is on customer.8.3 Caution against static chargeThe LCD module use C-MOS LSI drivers, so we recommended that you: Connect any unused input terminal to Vdd or Vss, do not input any signals before power is turned on, and ground your body, work/assembly areas, assembly equipment to protect against static electricity.8.4 packingModule employ LCD elements and must be treated as such.Avoid intense shock and falls from a height.To prevent modules from degradation, do not operate or store them exposed direct to sunshine or high temperature/humidity8.5 Caution for operationIt is an indispensable condition to drive LCD’s within the specified voltage limit since the higher voltage then the limit cause the shorter LCD life.An electrochemical reaction due to direct current causes LCD’s undesirable deterioration, so that the use of direct current drive should be avoided.Response time will be extremely delayed at lower temperature then the operating temperature range and on the other hand at higher temperature LCD’s how dark color in them. However those phenomena do not mean malfunction or out of order with LCD’s, which will come back in the specified operation temperature.If the display area is pushed hard during operation, some font will be abnormally displayed but it resumes normal condition after turning off once.A slight dew depositing on terminals is a cause for electro-chemical reactionresulting in terminal open circuit.Usage under the maximum operating temperature, 50%Rh or less is required.8.6 storageIn the case of storing for a long period of time for instance, for years for the purpose or replacement use, the following ways are recommended.Storage in a polyethylene bag with the opening sealed so as not to enter fresh air outside in it . And with no desiccant.Placing in a dark place where neither exposure to direct sunlight nor light’s keeping the storage temperature range.Storing with no touch on polarizer surface by the anything else.[It is recommended to store them as they have been contained in the inner container at the time of delivery from us8.7 SafetyIt is recommendable to crash damaged or unnecessary LCD’s into pieces andwash off liquid crystal by either of solvents such as acetone and ethanol, which should be burned up later.When any liquid leaked out of a damaged glass cell comes in contact with your hands, please wash it off well with soap and water9. Precaution for use9.1A limit sample should be provided by the both parties on an occasion when the both parties agreed its necessity. Judgment by a limit sample shall take effect after the limit sample has been established and confirmed by the both parties.9.2On the following occasions, the handing of problem should be decided through discussion and agreement between responsible of the both parties.When a question is arisen in this specificationWhen a new problem is arisen which is not specified in this specifications When an inspection specifications change or operating condition change in customer is reported to Daxian , and some problem is arisen in this specification due to the changeWhen a new problem is arisen at the customer’s operating set for sample evaluation in the customer site.10.
